Calibrated data of stable water isotope measurements in water vapour at 8 m a.s.l. on the port side of the ship, made in the austral summer of 2016/2017 around the Southern Ocean during the Antarctic Circumnavigation Expedition.
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 8 m a.s.l. on the port of the ship, taken around the Southern Ocean during the Antarctic Circumnavigation Expedition (A...

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 8 m a.s.l. on the port of the ship, taken around the Southern Ocean during the Antarctic Circumnavigation Expedition (ACE) from November 2016 to April 2017 using a Picarro laser spectrometers L2120. The data provide 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 (Kozachek, 2020; DOI 10.5281/zenodo.3667535). 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 side (DOI:10.5281/zenodo.3739335) and 13.5 m a.s.l (DOI:10.5281/zenodo.3250790). Dataset contents Measurements on portside: ACE_watervapour_isotopes_SWI8-ps_1h.csv, data file, comma-separated values ACE_watervapour_isotopes_SWI8-ps_5min.csv, data file, comma-separated values cal_runs_SWI8-ps.csv, metadata, comma-separated values cal_flag_times_SWI8-ps.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.
