An Improved Aerosol Retrieval Algorithm for FY-4A/AGRI Data Based on the GRASP Framework

IEEE Transactions on Geoscience and Remote Sensing
Accurate satellite-derived aerosol optical depth (AOD) with high temporal resolution is crucial for monitoring diurnal aerosol variations and understanding their impacts on atmospheric processes and air quality.

Investigating SST diurnal variation and its response to the MJO in the North Indian Ocean using FY-4A data

Frontiers in Marine Science
Sea surface temperature (SST) diurnal variation is an important part of air-sea energy exchange, and its response to the Madden–Julian Oscillation (MJO) also helps in studying the development mechanism of the MJO.

Collaborative Estimation and Downscaling-Based Validation of Hemispherically Integrated Surface Upward Longwave Radiation From FY-4A AGRI and Himawari-8 AHI Sensors

IEEE Geoscience and Remote Sensing Letters
Thermal radiation directionality (TRD) describes the anisotropic signature in the thermal infrared domain, leading to significant uncertainties in current land surface temperature (LST) and surface upward longwave radiation (SULR) products.
