Microwave Radiometer Type: HATPRO (Humidity and Temperature PROfiler) Generation 4, manufactored by Radiometer Physics GmbH, Meckenheim, Germany. The HATPRO has seven K band (22.235-31.4 GHz) channels as well as seven V band channels (51.2-58.0 GHz). The brightness temperature measurements in these bands are sensitive for the humidity profile, the vertically integrated amount of cloud liquid water and the temperature profile, respectively. The files contain 14 brightness temperatures as a function of measurement time, elevation and azimuth angle observing direction. Additionally included are temperature, pressure and humidity at the instrument location as well quality flags characterizing the instrument performance. Note, that brightness temperature values are given for all available times so that it is up to the user to decide whether or not to use the values if quality flags are set. Provided uncertainties describe the expected random error of the brightness temperature channels (variance) for each measurement in addition to the covariances among the different channels. Also included is the expected systematic uncertainty for brightness temperature when carying out a absolute calibration (Maschwitz et al., 2012 in Atmospheric Measurement Techniques).
