Reconstruction of Three-Dimensional Cloud Structures Using FY-4B AGRI Observations and CMA-MESO Forecasts

Accurate observation of cloud parameters is critical for weather forecasting, climate model improvement, and extreme-weather warning, yet the reconstruction of three-dimensional cloud structures remains a major challenge. In this study, geostationary infrared observations from FY-4B AGRI are combined with CMA-MESO ba...

Direct Assimilation of Satellite Visible and Near‐Infrared Radiances to Improve Aerosol Simulations

Existing satellite‐based aerosol data assimilation approaches mostly rely on assimilating retrieved aerosol products, which suffer from inconsistencies between retrieval assumptions and model representations, as well as uncertainties in the retrieved aerosol parameters. Here we develop a direct shortwave radiance assim...
