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 clwvi as a function of measurement time, elevation and azimuth angle observing direction. clwvi is based on multi-variate regression retrievals. Provided uncertainties describe the expected standard error of prw. Note, that clwvi 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.
Limitations: none
Provenance: none
Comments: clwvi errors are given as a function of retrieval elevation angle. Note, observations may occur at different angles (interpolation).
