Raw meteorological measurements from the Arctic century expedition in August/September 2021

A Vaisala MAWS240 meteorological station measured air temperature, relative humidity, dew point temperature and air pressure at a temporal resolution of 30sec and wind speed and wind direction at 3sec resolution. Measurements were conducted on starboard and port side at 20 m above sea level.

These measurements need to be post-processed before further usage to remove calibration periods and wind flow distortion effects due to the ship’s superstructure. A post-processed dataset is available with the following doi: doi.org/10.3929/ethz-b-000693692. The data are provided by the Arctic Century Expedition, a joint initiative led by the Swiss Polar Institute (SPI), the Antarctic and Arctic Research Institute (AARI) and GEOMAR Helmholtz Centre for Ocean Research Kiel (GEOMAR) and funded by the Swiss Polar Foundation and AARI, Federal scientific and technological program for ecological development (Agreement № 169-03-2024-072).
