Description
Summary:Dataset abstract This data set includes the calibrated data of stable water vapour isotope (δ18O, δ2H, deuterium excess) and water vapour mixing ratio measurements at approximately 13.5 m a.s.l. taken around the Southern Ocean during the Antarctic Circumnavigation Expedition (ACE) from November 2016 to April 2017 using a Picarro laser spectrometer L2130. The data provides continuous timelines of atmospheric water vapour properties in the marine boundary layer for studies of the atmospheric water cycle. The raw data from which this calibrated dataset originates has been published separately (Thurnherr and Aemisegger, 2019; DOI 10.5281/zenodo.3664177). Two other calibrated stable water isotope measurement datasets were also collected during ACE. They differ by the location of measurement on the ship: 8 m a.s.l on the starboard (DOI:10.5281/zenodo.3739335) and port sides (DOI:10.5281/zenodo.3739354). Dataset contents ACE_watervapour_isotopes_SWI13_1h.csv, data file, comma-separated values ACE_watervapour_isotopes_SWI13_5min.csv, data file, comma-separated values cal_runs_SWI13.csv, metadata, comma-separated values data_file_header.txt, metadata, text format README.txt, metadata, text format NaN values denote missing values which occur because of e.g., maintenance, instrument calibration, large cavity variations.
