Comprehensive CLPX Ground Radiometer Data During Intensive Field Campaigns

This dataset consists of high-resolution ground radiometer measurements gathered during the Intensive Field Campaign (IFC) related to the CLPX project. It includes 30-minute intervals of Stokes' brightness temperatures across various frequencies (1.4, 6.9, 19, and 37 GHz) in both V- and H-polarizations, as well as thermal infrared brightness temperatures. Ground temperature, moisture, and heat flow data to -1m depth, along with snow temperature profiles, are also provided. Measurements are recorded at different times of day and vary from 0° to 1800° nadir angles, supporting comprehensive environmental analysis.
