BSRN (Baseline Surface Radiation Network) is a project of the World Climate Research Programme (WCRP) and the Global Energy and Water Experiment (GEWEX). This project aims at detecting changes in the Earth’s radiation field at the Earth’s surface that may be related to climate change. The data are of primary importance for the validation and evaluation of satellite and model estimates of radiative quantities. At a small number of stations (currently about 40) in contrasting climatic zones, covering a latitude range from 80°N to 90°S, solar and atmospheric radiation is measured with instruments of the highest available accuracy and with high time resolution (1 to 3 minutes). Early 2004 BSRN was designated as the global baseline network for surface radiation for the Global Climate Observing System (GCOS).
The radiation site in Cabauw (51.97°N, 4.93°E) is part of BSRN since 2005. The key quantities measured in Cabauw are:
