[A-CG52] Terrestrial monitoring using geostationary satellites

Wed. May 27, 2026 9:00 AM - 10:30 AM 106 (International Conference Hall, Makuhari Messe)

Chairperson:Yamamoto Yuhei(Center for Environmental Remote Sensing, Chiba University), Miura Tomoaki(Univ Hawaii)

The launch of 3rd-generation geostationary satellites (Himawari-8/9, GOES-R, MTG, Fengyun-4, GeoKompsat-2A) has begun a new era in Earth observation. These satellites carry advanced sensors with spectral bands similar to those on polar-orbiting satellites, enabling high-frequency (e.g., 10-minute) monitoring of key land parameters like surface temperature, albedo, vegetation indices, evapotranspiration, and photosynthetic activity.

Integrating data from these geostationary (GEO) satellites with polar-orbiting (LEO) sensors (e.g., MODIS, VIIRS, SGLI) allows for consistent, global land monitoring. This session invites presentations on methods for estimating land parameters using combined GEO and LEO data, including their inter-calibration, cross-validation, and in-situ validation. We also welcome studies on novel applications of these datasets for monitoring phenomena such as heatwaves, droughts, and long-term climate change impacts. Furthermore, studies on the influence of atmospheric factors (e.g., clouds, aerosols) on land surface conditions are highly encouraged.
