| Abstract: | This paper describes an intercomparison between the Väisälä, VIZ and Swiss (used at upper-air station 06610) radiosondes. The field experiment was supported by a series of carefully implemented laboratory tests. The results show that the temperature sensor data from the SMI and VIZ sondes both require additional radiation compensation for daylight ascents whilst the Swiss sonde's pressure sensor has particularly large errors in the 200–100 mb region. New correction parameters have been determined for the SMI and VIZ sondes and these have now been built into the systems' software. |
