Summary

Description

This data set presents more than 400 sub-canopy digital thermograms collected at the Fraser Experimental Forest (Fraser, Colorado, USA) using an Infrared Solutions IR SnapShot™ thermoelectric thermal infrared (IR) imaging radiometer that was cold-weather modified. To view the data it is necessary to have the Infrared Solutions SnapView™ software, which is available from Infrared Solutions. The NASA Cold Land Processes Field Experiment (CLPX) is a multi-sensor, multi-scale experiment that focuses on extending a local-scale understanding of water fluxes, storage, and transformations to regional and global scales. Within a framework of nested study areas in the central Rocky Mountains of the western United States, ranging from 1 ha to 160,000 km2, intensive ground, airborne, and spaceborne observations are collected. Data collection focuses on two seasons: mid-winter, when conditions are generally frozen and dry, and early spring, a transitional period when both frozen and thawed, dry and wet conditions are widespread.
