Eddy-covariance measurements collected during two austral summers in the Schirmacher oasis, East Antarctica.
The data set includes eddy-covariance measurements collected during two field campaigns (2017–2018 and 2019–2020) carried out in the Schirmacher oasis, East Antarctica (70° 45′ S, 11° 44′ E). During the campaigns, the integrated CO2 and H2O open-path gas analyzer and 3-D sonic anemometer Irgason by...

| Summary: | The data set includes eddy-covariance measurements collected during two field campaigns (2017–2018 and 2019–2020) carried out in the Schirmacher oasis, East Antarctica (70° 45′ S, 11° 44′ E). During the campaigns, the integrated CO2 and H2O open-path gas analyzer and 3-D sonic anemometer Irgason by Campbell Scientific (the serial number 1243) was operated on the shore of two glacial lakes. In the first experiment, the Irgason was deployed on the north-west shore of Lake Zub/Priyadarshini at a distance of 10 m from the coast used from 01.01.2018 to 07.02.2018. The instrument was placed on the aluminium tripod on the height of 2 m, and its sensor was directed toward 137° south-eastwards (SE). The second experiment lasted from 07.12.2019 to 13.01.2020; the Irgason was deployed at a distance of 10 m from the shore of Lake Glubokoe at a height of 1.8 m and the sensor was directed toward 144° south-eastwards (SE). The data are stored in the datafiles with the format given in Irgason_output.pdf; the raw data are packed into the *.dat files (one per day) and then compressed (bz2). The calibration of the Irgason was done 21.08.2017 and 13.11.2019 in the lab of the Finnish Meteorological Institute with standard zero-and-span procedure, and then the instrument was adjusted accordingly. The Irgason joined the inter-calibration campaign carried out in October 2018 in Lake Alqueva (Portugal). The work has received financial support from the Academy of Finland (contract number 304345, PI Timo Vihma); the logistic support of the field campaigns provided by the Finnish Antarctic Research Program and the Russian Antarctic Expedition. |
