From 2005-02-26 to 2005-03-19 a total of 158 radiosondes were launched from RV Celtic Explorer at intervalls of about 3 hours. Measured parameters are temperature, pressure and humidity. Wind direction and speed are calculated from GPS positioning. The dataset consists of one archive file (.tar) which contains 158 data files, one for each sounding. The file format is 'ascii-text', the representation of measured parameters is described in a 'readme'-file inside the .tar-archive and in the 'additional_info' entry (LOFZY2005_celtic_rs_info).

The data has been quality checked. Obviously wrong measurements have been sorted out. For details on sensor type, sensor accuracy, launching procedure, ground check etc. see the 'additional_info' entry (LOFZY2005_celtic_rs_info).

Consistency report
Few dates may be missing due to equipment failure or severe weather. Some sounding may contain data gaps due to transmission errors. Wind data shortly after launch may be intermittent due to GPS problems.
