Description

The used microwave radiometer TOPHAT has seven V band (51.8-58.8 GHz) channels that are sensitive to atmospheric temperature (ta). These files contain ta as a function of measurement time, height above ground, elevation and azimuth angle observing direction. The retrieved ta profile is based on multi-variate regression retrievals. Provided uncertainties describe the expected standard error of ta as a function of height above ground. Note, that ta 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. For details on TOPHAT at the JOYCE supersite please refer to http://gop.meteo.uni-koeln.de/ag_crewell/doku.php?id=instruments:tophat:tophat. TOPHAT was installed at JOYCE on 22.7.2010 as has been measuring in a 24/7 mode since then.
