This paper presents the ongoing development of a demonstrator for the Geostationary Atmospheric Sounder (GAS) instrument. GAS utilizes synthetic aperture radiometry to obtain desired spatial (30 km) and temporal (nowcasting) resolution for measurement of atmospheric temperature and humidity profiles under all weather conditions. These parameters are decisively important to meteorological and climate models at all time scales. The instrument development project includes on-ground demonstration of both the imaging performance and the mechanical concept.
