The mission geosynchronous – continental land atmosphere sensing system (G-CLASS) is designed to study thediurnal water cycle, using geosynchronous radar. Although the water cycle is vital to human society, processes on timescalesless than a day are very poorly observed from space. G-CLASS, using C-band geosynchronous radar, could transform this. Itsscience objectives address intense storms and high resolution weather prediction, and significant diurnal processes such assnow melt and soil moisture change, with societal impacts including agriculture, water resource management, flooding, andlandslides. Secondary objectives relate to ground motion observations for earthquake, volcano, and subsidence monitoring. Theorbit chosen for G-CLASS is designed to avoid the geosynchronous protected region and enables integration times of minutesto an hour to achieve resolutions down to ~20 m. Geosynchronous orbit (GEO) enables high temporal resolution imaging (up toseveral images per hour), rapid response, and very flexible imaging modes which can provide much improved coverage at lowlatitudes. The G-CLASS system design is based on a standard small geosynchronous satellite and meets the requirements ofESA's Earth Explorer 10 call.
