SUMMARY:The Hub Talks:  Carbon Mapper - Global distributions of super-emitting methane point sources as detected by satellites
DESCRIPTION:Speaker: Daniel Cusworth is the Science Director for Carbon Mapper. Carbon Mapper’s mission is to drive greenhouse gas emission reductions by making methane and carbon dioxide data accessible and actionable. Daniel oversees algorithm development\, validation\, analysis\, and applications of airborne and satellite greenhouse gas datasets. He was formerly a Data Scientist at the NASA Jet Propulsion Laboratory and a Research Scientist at University of Arizona and worked on quantification of anthropogenic carbon dioxide and methane emissions from regional to facility scales. He received his B.S. in Applied Math/Atmospheric Sciences at UCLA and Ph.D. in Atmospheric Chemistry at Harvard University. \n\n\n\n \n\n\n\nAbstract: Super-emitting (>100 kg/h) methane sources likely contribute significantly to total emissions across several oil&gas basins\, but the robust quantification and characterisation of these sources remains uncertain in absence of routine\, transparent\, and robust measurements. Solving this quantification gap is particularly important given international regulations and initiatives to require low methane intensities across the oil&gas supply chain by country and operator. The Tanager-1 satellite (launched August 2024) has shown capability of detection and quantification of the vast majority of methane super-emitters given adequate observing conditions and spatiotemporal coverage. Here we show Carbon Mapper’s progress in mapping super-emitter distributions and quantifying super-emitter intensities through intensive tasking of the Tanager-1 satellite of the majority of oil and gas infrastructure across key oil&gas producing countries. With 30-m spatial resolution of Tanager-1\, we attribute each detection to facility and equipment type\, allowing for better understanding of drivers of intensities and how those drivers vary across basins. Significant distributions of super-emitters are routinely detected in Tanager-1 across austere environments (e.g.\, high latitude\, snow-covered)\, allowing for increased transparency of emission sources in regions that have been typically under-observed. Building a more complete global picture of super-emitters with attribution to infrastructure will aid in constructing mitigation roadmaps for lower-intensity energy. \n\n\n\n\n\n\n\n\n\n\n\n\n\nMicrosoft Teams Need help? \n\n\n\nJoin the meeting now \n\n\n\nMeeting ID: 328 369 308 984 \n\n\n\nPasscode: fY6LQ6Le \n\n\n\n\n\n\n\nDial in by phone \n\n\n\n+39 02 0062 4740\,\,986432030# Italy\, Milan \n\n\n\nFind a local number \n\n\n\nPhone conference ID: 986 432 030# \n\n\n\nJoin on a video conferencing device \n\n\n\nTenant key: teams@meet.esa.int \n\n\n\nVideo ID: 125 398 688 0 \n\n\n\nMore info \n\n\n\nFor organizers: Meeting options | Reset dial-in PIN \n\n\n\n\n\n\n\nOrg help | Privacy and security

SUMMARY:The Marine Heat Waves from space: from detection to prediction workshop.
DESCRIPTION:Marine Heat Waves (MHWs) — periods of abnormally high sea surface temperatures lasting several days — are becoming more frequent and intense under climate change. Enhancing our capacity to monitor and predict them is now crucial — not only for science\, but also for society and ocean health. \n\n\n\n\n\n\n\nThe event gathers 25 experts from 11 countries to exchange insights and shape future research around four core objectives: improving MHW detection\, enhancing observability\, advancing predictability\, and assessing impacts. A major outcome will be a White Paper summarizing key challenges and opportunities and outlining a roadmap for future MHW-related activities. \n\n\n\nMore information on the workshop is available The Marine Heat Waves from space: from detection to prediction workshop.

SUMMARY:The Hub Talks: Cloud radiative imbalance in global 3D radiative transfer simulations
DESCRIPTION:Speaker: Giulia Roccetti is a visiting us in the Science Hub from 14th to 21st ofOctober. Giulia recently finished her PhD at the European Southern Observatoryand has started a research fellowship position at ESA/ESAC. There\, she will useEarthCARE data\, among other resources\, to study how 3D cloud structure affectstheir radiative effect.Abstract: We use 3D cloud fields from the ERA5 reanalysis product to model global-scale 3D radiative transfer in the Earth’s atmosphere. However\, strong biases emerge due to the coarse spatial resolution of the ERA5 cloud data. To address this limitation\, we have developed a 3D cloud generator capable of representing sub-grid cloud variability and heterogeneity within the ERA5 framework. Using this approach\, we find that the simulated cloud radiative effects converge at a horizontal resolution of approximately 6 km. Our next step is to validate this global 3D cloud generator using EarthCARE cloud products and to further investigate how horizontal resolution influences the modeled radiative effects of clouds. \n\n\n\n\n\n\n\n\n\nJoin the meeting now \n\n\n\nMeeting ID: 311 093 910 796 8 \n\n\n\nPasscode: Po2LV2WT \n\n\n\n\n\n\n\nDial in by phone \n\n\n\n+39 02 0062 4740\,\,773341781# Italy\, Milan \n\n\n\nFind a local number \n\n\n\nPhone conference ID: 773 341 781# \n\n\n\nJoin on a video conferencing device \n\n\n\nTenant key: teams@meet.esa.int \n\n\n\nVideo ID: 121 774 623 3 \n\n\n\nMore info \n\n\n\nFor organizers: Meeting options | Reset dial-in PIN \n\n\n\n\n\n\n\nOrg help | Privacy and security \n\n\n\n________________________________________________________________________________

SUMMARY:The Hub Talks: The Science and Technology behind Spaceborne Doppler velocity measurements
DESCRIPTION:Abstract: The Earth Cloud\, Aerosol\, and Radiation Explorer (EarthCARE) 94-GHz Cloud Profiling Radar (CPR)\, is the first spaceborne Doppler radar that provides coincident measurements of reflectivity and Doppler velocity\, opening the path to quantifying vertical air motions and hydrometeor sedimentation velocities from space. The coming decade will feature several additional space-borne missions including the NASA-Investigation of Convective Updrafts (INCUS) and the JAXA-NASA Atmosphere Observing System (AOS) Precipitation Measurement Mission (PMM) and the ESA Wind Velocity Radar Nephoscope (WIVERN) explorer mission. Despite being deployed hundreds of kilometers above the Earth’s surface\, these planned missions are expected to offer unprecedented measurement capabilities\, that in many ways will be superior to those available today from suborbital platforms. Furthermore\, the convection measurement capabilities from the different planned space missions are based on different measurement techniques and are applied at different resolutions and detection limits. As such\, they will provide highly complementary insights into the different parts and processes of the spectrum of convection. Here\, we will review the scientific importance these measurements in cloud and precipitation studies and the technical challenges and approaches utilized by the different missions. \n\n\n\nShort bio: Pavlos Kollias received the B.Sc. and M.Sc. degrees in Physics and Environmental Physics from the University of Athens\, Athens Greece in 1994 and 1996 respectively and the Ph.D degree in meteorology from the University of Miami\, Miami FL in 2000.

SUMMARY:The Hub Talks: Probing the urban atmosphere from ground: the BAQUNIN project
DESCRIPTION:Speaker: Stefano Casadio ESA \n\n\n\nThe Boundary-layer Air Quality analysis Using Network of INstruments (BAQUNIN) Atmospheric Composition monitoring and Cal/Val supersite (www.baqunin.eu)\, will be described with particular focus on the urban component. The BAQUNIN activities started on 2015 (ESA IDEAS+ WP)\, with increasing support from ESA and EUMETSAT in the following 10 years. The project consortium is composed by SERCO Italy\, Univ. Sapienza\, CNR-ISAC\, CNR-IIA\, ARPA Valle d’Aosta\, and Sardegna Clima. Fruitful collaborations have been established with space agencies such as NASA and JAXA\, and with research institutes\, e.g. the University of Thessaloniki (GR) and INOE (RO).The mandate of BAQUNIN is to operate state-of-art instrumentation devoted to atmospheric monitoring and satellite Cal/Val in different environments\, being the urban observatory in the centre of Rome the pivotal component. The data distribution policy is to grant free and open access to all products through the BAQUNIN website\,and through PGN\, AERONET\, COCCON\, EUBREWNET\, SKYNET international networks. Cal/Val data are made available through the ESA Validation Data Centre (EVDC).Starting from the main motivations that lead to the realisation of the project and continuing with the description of the current setup and instrumental suite of the urban observatory\, the following concrete examples will then be discussed:a) long-term data series in urban environment: 30 years NO2 vertical column from ground and spaceb) validation of satellite products: trace-gases\, GHG\, cloud top/bottom height\, aerosolsc) correction of “reference” data: the AERONET AOD at 440nm case \n\n\n\nFor more BAQUNIN details\, documents\, and open data access: http://www.baqunin.eu \n\n\n\n\n\n\n\n\n\nMicrosoft Teams meeting \n\n\n\nJoin: https://teams.microsoft.com/meet/32557833884145?p=xo3EO8Qt4ApyCoCO6I \n\n\n\nMeeting ID: 325 578 338 841 45 \n\n\n\nPasscode: ii7Xa7aC \n\n\n\nNeed help? | System reference \n\n\n\nDial in by phone \n\n\n\n+39 02 0062 4740\,\,172535451# Italy\, Milan \n\n\n\nFind a local number \n\n\n\nPhone conference ID: 172 535 451# \n\n\n\nJoin on a video conferencing device \n\n\n\nTenant key: teams@meet.esa.int \n\n\n\nVideo ID: 122 681 065 1 \n\n\n\nMore info \n\n\n\nFor organizers: Meeting options | Reset dial-in PIN \n\n\n\n\n\n\n\nOrg help | Privacy and security \n\n\n\n________________________________________________________________________________

SUMMARY:The Hub Talks: TANGO:  The Twin Anthropogenic Greenhouse Gas Observers Mission
DESCRIPTION:Speaker:  Dr Jochen Landgraf\, SRON\, Netherlands \n\n\n\nShort Bio: Jochen Landgraf is a senior scientist at SRON\, the Netherlands Institute for Space Research\, and a docent at the Institute for Environmental Physics of Heidelberg University. At SRON\, he leads a research group specializing in atmospheric remote sensing of trace gasses using observations from TANGO\, TROPOMI\, Sentinel‑5\, GOSAT (1 and 2) and GOSAT-GW. His group has developed algorithms and software for the operational retrieval and processing of CO and CH₄ data for the Sentinel‑5P and Sentinel‑5 missions. In multiple studies\, his team has demonstrated advanced retrieval applications of Sentinel‑5P CO and CH₄ data products and CO2 an CH4 retrieval from GOSAT\, OCO-2 and GOSAT-2 measurements. Currently\, he is involved in the Sentinel-5 data inspection during the commissioning phase of the mission. \n\n\n\nHe is a member of the Sentinel‑4/Sentinel‑5 and CO₂M mission advisory his primary scientific expertise lies in atmospheric radiative transfer and inverse modeling of atmospheric measurements and extends to the development of novel measurement concepts and the definition of instrument specifications. For instance\, he successfully proposed the Multi-Angle Polarimeter (MAP) as a payload instrument for the CO₂M mission. For SPEXone on NASA’s PACE mission\, he led the development of the Level‑1A to Level‑1C data processor\, providing him with detailed experience processing raw instrument data. In his role as Principal Investigator for the TANGO mission\, he has gained comprehensive insight into general mission-level challenges\, ground segment architectures\, end-to-end simulation analysis\, and the required trade-offs ‐ between mission constraints and scientific objectives\, including the use of flux inversion techniques for quantifying hotspot emission estimates. \n\n\n\n\nAbstract: \n\n\n\nThe Twin Anthropogenic Greenhouse Gas Observers (TANGO) mission is a small satellite mission to be launched in 2028\, under the ESA Scout Programme tapping into NewSpace to quickly deliver affordable and innovative science\, as part of ESA’s FutureEO Programme a schedule of three years from mission kick-off to launch. Designed to complement the Copernicus atmospheric monitoring missions Sentinel-5 Precursor\, Sentinel‑4/5\, and the CO2M carbon dioxide monitoring mission\, TANGO will observe carbon dioxide and methane emissions from human activities to support verification of the Paris Agreement. The mission is anticipated to generate >10\,000 emission estimates per year for major industrial facilities and power plants. The scientific community will be able to propose specific observation targets\, which will be incorporated into mission planning alongside routine observations aimed at enhancing current state-of-the-art point-source emission inventories. \n\n\n\nTwo agile CubeSat-class satellite buses\, each carrying an imaging spectrometer\, will operate in close formation with a temporal separation of less than 1 minute\, enabling near-sequential observations of the same target area. Platform agility is ensured by three-axis stabilized reaction wheel control\, which permits flexible spectrometer pointing with a roll capability of ±30° and forward motion compensation. This forward motion compensation increases the effective integration time by up to a factor of five\, thereby enhancing spatial coverage and improving the precision of the retrieved geophysical quantities. As part of the mission implementation\, a dedicated ground segment will be established to provide the scientific user community with open and freely accessible data products. These will include calibrated top-of-atmosphere radiance measurements (Level-1b)\, column-averaged dry air mole fractions of CO2 (XCO2) and CH4 (XCH4)\, as well as tropospheric NO2 column densities (Level-2)\, and corresponding emission estimates for CO2\, CH4\, and NO2 (Level-4). TANGO’s first satellite\, TANGO-Carbon\, will measure solar-reflected radiances in the 1.6 µm spectral region with a spectral resolution of 0.45 nm\, enabling the detection of moderate to strong CH4 emissions (≥ 5 kt yr⁻¹) and CO2 emissions (≥ 2.5 Mt yr⁻¹). The TANGO-Nitro instrument will provide collocated NO2 observations derived from radiance measurements in the visible spectral range with a spectral resolution ≤ 0.6 nm\, facilitating plume detection and the use of the NO2 for improved source characterization and emission quantification. In this contribution\, we describe the status of the TANGO mission\, the planned data products up to Level 4\, the associated scientific opportunities\, and the mechanisms for engagement of the scientific community in data exploitation. \n\n\n\nMicrosoft Teams meeting\n\n\n\n\n\n\n\nJoin: https://teams.microsoft.com/meet/32557833884145?p=xo3EO8Qt4ApyCoCO6I \n\n\n\nMeeting ID: 325 578 338 841 45 \n\n\n\nPasscode: ii7Xa7aC \n\n\n\n\n\n\n\nNeed help? | System reference \n\n\n\nDial in by phone \n\n\n\n+39 02 0062 4740\,\,172535451# Italy\, Milan \n\n\n\nFind a local number \n\n\n\nPhone conference ID: 172 535 451# \n\n\n\nJoin on a video conferencing device \n\n\n\nTenant key: teams@meet.esa.int \n\n\n\nVideo ID: 122 681 065 1 \n\n\n\nMore info \n\n\n\nFor organizers: Meeting options | Reset dial-in PIN \n\n\n\n\n\n\n\nOrg help | Privacy and security \n\n\n\n________________________________________________________________________________

SUMMARY:The Hub Talks Special Edition: Methane Emission Insights from MethaneSAT mission: Ritesh Gautam (EDF)
DESCRIPTION:Speaker: Dr. Ritesh Gautam\, Environmental Defense Fund (EDF) \n\n\n\nShort bio: Dr. Ritesh Gautam is a Lead Senior Scientist on MethaneSAT and MethaneAIR missions at Environmental Defense Fund (EDF). He oversees remote sensing projects at EDF in order to produce actionable data products and policy-relevant insights for quantifying and mitigating methane emissions\, leveraging the broader multi-satellite ecosystem. Dr. Gautam ensures EDF’s policy strategy to inform emission mitigation efforts are grounded in science-based observations and high-impact research. Prior to EDF\, he served as a tenured faculty member at the Indian Institute of Technology (IIT) Bombay\, and previously was a Research Scientist at NASA Goddard Space Flight Center. His research interests over the last two decades include remote sensing of methane\, aerosols\, clouds and cryosphere\, as well as developing improved understanding of pollution effects on air quality\, climate and monsoon. He has published over 80 papers including in PNAS\, Nature Communications\, Science Advances. Dr. Gautam is a recipient of the Scientific Leadership Award by NASA Goddard’s Earth Science Division. He serves as co-Chair of the ACAM program – a joint IGAC/APARC activity on Atmospheric Composition and Asian Monsoon (ACAM)\, focused on scientific workshops\, capacity building and field campaigns coordination. \n\n\n\nAbstract: \n\n\n\nThe past two and a half decades have witnessed a revolution in methane remote sensing techniques\, platforms and emission quantification approaches. Successive satellite missions starting from SCIAMACHY followed by GOSAT and TROPOMI missions have provided high-quality scientific data on methane at the global scale. This talk will focus on MethaneSAT which was designed to directly provide policy-relevant data on emissions for monitoring and mitigation\, with unprecedented science requirements to obtain the highest possible precision from space. MethaneSAT made observations during 2024-2025 and the analysis of emissions data focused on the oil and gas sector\, with select agricultural regions around the world. The specific emission data products include total regional methane emissions\, diffuse area emissions and high-emitting point sources. With a swath width of 220 km at nadir\, extendable to greater than 400 km mapping due to the satellite’s pointing capability\, MethaneSAT acquired high-resolution images that mapped oil and gas basins around the world. The underlying data are spatially resolved at 110 m x 400 m\, with a column integrated methane retrieval precision of ~3 ppb aggregated to 2 km x 2 km. The high-precision measurements were an integral requirement of the satellite mission detecting fine-scale enhancements\, thus providing robust quantification of regional emissions and revealing individual emission hotspots. Methane fluxes are produced\, using atmospheric inversion techniques\, as spatially gridded data products of 4 km x 4 km resolution covering oil and gas basins and agricultural regions. In addition to MethaneSAT\, it’s airborne version MethaneAIR has flown across the contiguous USA and collects similar high-precision and higher-resolution data providing an independent assessment of regional methane emissions. We will present a comprehensive synthesis of emissions data from major oil/gas basins around the world. The data are publicly available via Google Earth Engine and Google Cloud\, with further information available at methanesat.org. \n\n\n\n \n\n\n\n________________________________________________________________________________ \n\n\n\nMicrosoft Teams meeting \n\n\n\n\n\n\n\nJoin: https://teams.microsoft.com/meet/324629278100396?p=n7lwR4cvbKqdn69ZkL \n\n\n\nMeeting ID: 324 629 278 100 396 \n\n\n\nPasscode: hK9M5tH2 \n\n\n\n \n\n\n\nNeed help? | System reference \n\n\n\nDial in by phone \n\n\n\n+39 02 0062 4740\,\,314746147 Italy\, Milan \n\n\n\nFind a local number \n\n\n\nPhone conference ID: 314 746 147# \n\n\n\nJoin on a video conferencing device \n\n\n\nTenant key: teams@meet.esa.int \n\n\n\nVideo ID: 128 256 400 8 \n\n\n\nMore info \n\n\n\nFor organizers: Meeting options | Reset dial-in PIN \n\n\n\n\n\n\n\nOrg help | Privacy and security
