The In-Situ Sensing Facility (ISF) provides measurements made directly in the environment as well as profiling measurements of the lower atmosphere. Measurements are made in-situ at the earth's surface, on towers, on balloons, and on packages dropped from aircraft. Profiling measurements are made using vertically pointing radar, lidar and acoustic sensors.  

We aim to serve the advanced observational needs of the atmospheric science community by providing a flexible, state-of-the-art backbone measurement capability applicable to a wide range of experimental needs - emphasizing advanced sensor capabilities, sensor integration, system mobility, and the ability to deploy to remote or difficult locations. ISF is divided into three groups:

The Surface Group

The Surface Group focuses on systems to measure the surface layer, surface energy budget and surface properties. This group deploys the ISFS (Integrated Surface Flux System) and CentNet facilities, and operates the EOL calibration lab.

The Sounding Group

The Sounding Group focuses on sensors dropped from aircraft and balloons, as well as their associated data systems. This group deploys the AVAPS (Airborne Vertical Atmospheric Profiling System), Dropsonde and Driftsonde facilities.

The Atmospheric Profiling Group

The Atmospheric Profiling Group focuses on instruments to profile the atmosphere, particularly radar wind profilers and radiosonde soundings. This group deploys the ISS (Integrated Sounding System) and GAUS (GPS Advanced Upper-Air Sounding system) facilities.
