2023年4月23-28日，欧洲地学联盟( European Geosciences Union ,简称EGU) 年会在奥地利维也纳召开。mgm美高梅79906秦凯教授、Jason Cohen教授、时洪涛讲师、博士生何秦、博士生蒋兴兴、博士生刘哲文、博士生陆凌霄、硕士生胡玮参加了本次会议。本届年会是近年来规模最大、人数最多的一次地学盛会。它涵盖地球科学的多个分支方向，共有18831名注册参会者，其中来自107个国家的15453名线下参会者。

会议期间，秦凯教授在“Satellite observations of tropospheric composition and pollution, analyses with models and applications”专题张贴了题为“A high spatial and temporal coverage global gridded tropospheric NO2 dataset (2007-2021) based on OMI and GOME-2”的学术海报；

Jason Cohen教授在“Composition-Climate Interactions including regional aerosol impacts”专题张贴了题为“Top-Down Model-Free Computed Emissions, Size, Mixing State, and Radiative Forcing of BC, CO, and NOx: Increased Emissions and Less Negative Radiative Forcing in Rural Areas Coupled with Reduced Emissions and More Variable Radiative Forcing in Urban Areas”；

时洪涛讲师在“Remote Sensing of Soil Moistur”专题作了题为“Soil Moisture Estimation over Crop Fields Combined with Fully Polarimetric SAR and Passive Microwave Products Data”的口头报告；

博士生何秦在“Satellite observations of tropospheric composition and pollution, analyses with models and applications”专题作了题为“Exploring the utility of global high-resolution NO2 columns from TROPOMI for investigating the diurnal variability and downscaling historical measurements”的口头报告；

博士生蒋兴兴和博士生刘哲文在“Remote Sensing of Clouds and Aerosols: Techniques and Applications”专题分别作了题为“Retrieval of aerosol single scattering albedo over land using geostationary satellite data”和“Characterizing Emissions from Energy Sources Using Aerosol Properties Over Multiple-Wavelengths”的PICO报告；

博士生陆凌霄在“Atmospheric composition variability and trends”专题作了题为“Computing Daily NOx Inversion over Energy Consuming and Urbanized Regions Using TROPOMI Data – A Novel Model Free Approach”的PICO报告；

博士生胡玮同学在“Quantification of anthropogenic methane sources through atmospheric measurement studies: Finding targets for mitigation worldwide”专题张贴了题为“Chinese Coal Mines Methane Emissions Constrained by High-Frequency Measurements”的学术海报。
