BASIS1998_umea_rs: 6-hourly radiosoundings, launched at station Umea, 66 soundings
From 1998-02-17 to 1998-03-06 a total of 66 radiosondes were launched at station Umea at intervalls of about 6 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 66 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 (BASIS1998_umea_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 (BASIS1998_umea_rs_info).
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.
