Cold Land Processes Experiment

The Campaign

The Cold Land Processes Experiment (CLPX) was a NASA field campaign focused on enhancing understanding of cold land processes to improve satellite measurements and develop new observation methods. CLPX included two phases: CLPX-I and CLPX-II. CLPX-I took place during the boreal spring and winter of 2002 to 2003 across the Central Rocky Mountains in Colorado. Remote sensing instruments like the Airborne Synthetic Aperture Radar (AIRSAR), Polarimetric Scanning Radiometer, and Polarimetric Ku-Band Scatterometer (PolSCAT) were used to gather data on snow properties and land features. Ground-based measurements of soil moisture, snow depth, and meteorological conditions were also collected. CLPX-II aimed to acquire Ku-band radar data of snow water equivalent (SWE) for satellite validation with the PolSCAT instrument. It occurred during the boreal winter of 2006 to 2007 in Colorado and 2007 to 2008 in Alaska. The project was funded by NASA’s Terrestrial Hydrology Program.
