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

Abstract

This data set contains raw meteorological observations from the Arctic century expedition on the R/V Akademik Tryoshnikov in August and September 2021 in the Barents, Laptev and Kara Sea. 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: https://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).
