Mission

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. Remote 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:

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 Laboratory.

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 Dropsonde System on HIAPER and the C-130 aircraft at RAF. The group also developed and deployed the high latitude long duration balloon based Driftsonde system.

Atmospheric Profiling Group

The Atmospheric Profiling Group focuses on instruments to profile the atmosphere, particularly radar wind profilers, radiosonde soundings and basic surface measurements . This group deploys the ISS (Integrated Sounding System).
