gndrad > Ground Radiometers on Stand for Upwelling RadiationInstrument Type(s) > Baseline

The Ground Radiation (GNDRAD) collection of radiometers provides continuous measurements of broadband reflected shortwave (solar) and longwave (infrared) irradiances for upwelling components. These 1-minute data are collected to help determine the total radiative energy exchange at a research site.

At GNDRAD sites, collocated downwelling shortwave and longwave irradiances are also normally measured (see SKYRAD).
