CLPX Airborne Gamma Snow and Soil Moisture Surveys, Version 1
Data set id:
NSIDC-0158
DOI: 10.5067/38UW2772KQER
This is the most recent version of these data.
Overview
Airborne gamma surveys were conducted over each of the three Cold Land Processes Field Experiment (CLPX) Meso-cell Study Areas (MSAs) in northern Colorado, USA, during September 2001 and 2002, and during the three Intensive Observation Periods (IOPs) in February 2002 (IOP1), February 2003 (IOP3) and March 2003 (IOP4). Data collected in September 2001 and 2002 provided background gamma radiation measurements necessary to calculate measurements of snow water equivalent (SWE) and soil moisture during subsequent winters.
