General Overview
The Ground Radiation (GNDRAD) collection of radiometers provides the TWP, NSA, and AMFs with continuous measurements of broadband shortwave (solar) and longwave (infrared) irradiances for upwelling components. These 1-minute data are collected to help determine the total radiative energy exchange at each specific research site location.
NOTE: See ARM Pyrgeometer Calibrations & Field Measurements: Information Regarding the Data Restriction Notice (PowerPoint presentation).
