Cold Land Processes Experiment

The Campaign

The Cold Land Processes Experiment (CLPX) was a NASA field campaign that aimed to better understand cold land processes to improve spaceborne measurements and develop new observing capabilities. CLPX consisted of two deployments: CLPX-I and CLPX-II. CLPX-I occurred during the boreal spring and winter of 2002 to 2003 across the Central Rocky Mountains in Colorado. Airborne remote sensors, such as the Airborne Synthetic Aperture Radar (AIRSAR), Polarimetric Scanning Radiometer, and Polarimetric Ku-Band Scatterometer (PolSCAT), were used to collect measurements of snow properties and land characteristics. Ground-based observations of soil moisture, snow depth, and meteorological parameters were also collected. CLPX-II focused on collecting Ku-band radar retrievals of snow water equivalent (SWE) for satellite validation using the PolSCAT instrument. CLPX-II occurred during the boreal winter of 2006 to 2007 in Colorado and the boreal winter of 2007 to 2008 over Alaska. CLPX was funded through NASA’s Terrestrial Hydrology Program.
