The KNMI HATPRO radiometer is installed at the Cabauw Observatory and operated since May 2006. The brightness temperatures provided are the values as measured by the radiometer without any post-processing applied. The radiometer is calibrated with liquid nitrogen at half yearly intervals. Meteo variables measured with the sensors attached to the radiometer are included, as well as a quality flag.
Limitations: data not reliable during rainfall
Provenance: CESAR ( http://www.cesar-database.nl )
