From 1992-05-28 to 1992-06-21 a total of 156 radiosondes were launched from RV Valdivia at intervalls of about 3 hours. Measured parameters are temperature, pressure and humidity. Wind direction and speed are determined by OMEGA navigation system. The dataset consists of one archive file (.tar) which contains 156 data files, one for each sounding. The file format is 'ascii-text', the representation of the measured parameters is described in the 'readme'-file inside the .tar-archive and in the 'additional_info' entry (ASTEX1992_valdivia_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 'additional_info' entry (ASTEX1992_valdivia_rs_info).
Few dates may be missing due to equipment failure or severe weather. Some sounding may contain data gaps due to transmission errors.
