Significant Topographic Impacts on Moderate-Resolution Satellite Products: Evidence From Both Geostationary and Polar-Orbiting Satellites and Model Simulations

Congratulations to Dr. Yichuan Ma on publishing a research article on IEEE Transactions on Geoscience and Remote Sensing. The title of the article is “Significant Topographic Impacts on Moderate-Resolution Satellite Products: Evidence From Both Geostationary and Polar-Orbiting Satellites and Model Simulations” and it is now available at https://doi.org/10.1109/TGRS.2025.3572685

This study investigated how topography-induced deviations propagate through moderate-resolution satellite observations, product generation, and downstream applications. Specifically, three tasks were conducted: 1) examined the topographic effects on geostationary satellite data using GOES-16 and GOES-17 satellite data; 2) examined the impact of topography on polar-orbiting satellite products using MODIS-Terra and MODIS-Aqua data; 3) employed radiative transfer models to gain insights into how topography influences satellite data across different terrain conditions. The findings underscore the importance of integrating topographic considerations into high-level satellite products over mountainous regions.
