The International Earth Surface Working Group (IESWG) was established to help gather requirements specific to surface observations and to enhance both our understanding and ability to monitor the components of the Earth system including land, vegetation, snow, ice, and coastal and open waters.  The IESWG plenary sessions will be focused on preparing our recommendations and input to the CGMS WGII. Below the draft program.program.

Topics of particular focus included Earth Observations research & operational applications involving:

•     Snow, ice, and cryosphere-atmosphere interactions
•     Vegetation and land-atmosphere fluxes
•     Soil moisture, river-discharge, and water cycle

IESWG 2023 Co-Chairs: Dr. Ben Ruston (JCSDA) and Dr. Gianpaolo Balsamo (ECMWF).

Newly-elected IESWG Co-Chairs: Dr. Clara Draper (NOAA) and Dr. Gianpaolo Balsamo (ECMWF). Newly-elected Rapporteur to CGMS: Dr. Ben Ruston (JCSDA).
