- The Baseline Surface Radiation Network (BSRN) is a project of the
World Climate Research Programme (WCRP) aimed at detecting important
changes in the earth's radiation field which may cause climate
changes. At a small number of stations (fewer than 40) in contrasting
climatic zones, covering a latitude range from 80N to 90S (see station
maps), solar and atmospheric radiation is measured with instruments of
the highest available accuracy and at a very high frequency (minutes).
The radiation data are stored together with collocated surface and
upper-air observations and station `metadata' in an integrated
database at the WRMC. High accuracy BSRN radiation measurements are
already used to validate the radiation schemes in climate models and
to calibrate satellite algorithms.
