The used microwave radiometer HATPRO has seven K band (22.235-31.4 GHz) channels that are sensitive to the humidity profile (hua), the path integrated amount of cloud liquid water (clwvi) and the path integrated amount of water vapor (prw). These files contain hua profiles as a function of measurement time, height above ground, elevation and azimuth angle observing direction. The hua profile is based on multi-variate regression retrievals. Provided uncertainties describe the expected standard error of hua at each height. Note, that hua 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. Additionally included are temperature, pressure and humidity at the instrument location as well quality flags characterizing the instrument and retrieval performance.
