Attending the International Radiation Symposium 2024 (IRS2024) at Hangzhou (China)
Jaume Ruiz de Morales, PhD Student of the University of Girona involved in the NUBESOL-2 project has presented some results at the IRS 2024 (17 June - 21 June), a quadrennial congress that took place in Hangzhou, China. Jaume Ruiz de Morales at IRS2024, at Hangzhou (China) The IRS2024 was organized by the Zhejiang University (ZJU), along with the International Radiation Commission (IRC) of the International Association of Meteorology and Atmospheric Sciences (IAMAS). The meeting offered a multicultural ambience, where researchers from all over the world shared their latest findings on atmospheric radiation science. Jaume Ruiz de Morales [...]
Cloud-Aerosol Transition Zone: longwave radiative effect based on CERES observations
By Babak Jahani, Hendrik Andersen, Josep Calbó, Josep-Abel González and Jan Cermak. Publication: https://doi.org/10.5194/acp-22-1483-2022 The study presents an approach for quantification of cloud-aerosol transition zone broadband longwave radiative effects at the top of the atmosphere (TOA) during daytime over the ocean, based on satellite observations and radiative transfer simulation. The authors used several products from MODIS (Moderate Resolution Imaging Spectroradiometer) and CERES (Clouds and the Earth’s Radiant Energy System) sensors for the identification and selection of CERES footprints with horizontally homogeneous transition zone and clear-sky conditions. For the selected transition zone footprints, radiative effect was calculated as the difference between [...]
Quantifying Transition Zone Radiative Effects in Longwave Radiation Parameterizations
The change in the state of sky from cloudy to cloudless (or vice versa) comprises an additional phase called “transition zone,” in which the characteristics of the particle suspension lay between those corresponding to a pure cloud and those of atmospheric aerosols. This phase, however, is usually considered, in atmospheric monitoring and modeling, as an area containing either aerosol or thin clouds. This study quantifies the uncertainties that this binary assumption may introduce to the estimation of longwave radiative effects at the top and bottom of the atmosphere by using the Fu‐Liou‐Gu (FLG), NewGoddard, and Rapid Radiative Transfer Model for [...]
