FASTEX soundings from ASAP ship Irena Arctica

Summary

This dataset consists of sounding data from the Danish ASAP ship the Irena Arctica which was operated by the Danish Meteorological Institute. Soundings were taken four times per day (00, 06, 12, and 18 UTC) while the ship was within the FASTEX domain. These data were processed through the automated and visual quality control. This dataset includes pressure, temperature, dew point, relative humidity, wind speed, wind direction, and altitude taken at 10 second vertical intervals. Refer to the station README for details.
