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 the radiometer rainflag. The KNMI HATPRO is not equipped with an IR-sensor.
