In-Situ Sounding Facility (ISF) “Developing and deploying in-situ (and profiling) sensors and systems supporting a broad range of atmospheric research”
In-Situ Sounding Facility (ISF) Airborne Sounding group: Dropsondes, Driftsonde, Reference Radiosonde - extending the envelope of atmospheric profiling capabilities. Integrated Sounding System (ISS) and Rawinsonde Group Wind profiling technology (radar and sodar) combined with surface met and radiosondes for a virtual tall tower of capabilities. Integrated Surface Flux Facility (ISFF): Tower based and distributed sensors to study exchange processes between the atmosphere and Earth's surface.
