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________________________________________________________________________________
