Description

Dataset abstract

ERA-5 fields at 1-hour temporal and grid size of 0.25° x 0.25° (0.5° x 0.5° for wave variables) have been downloaded from https://cds.climate.copernicus.eu/api/v2/resources/reanalysis-era5-single-levels.

The data are interpolated using two methods:

'nearest': the value of the nearest ERA-5 grid cell is use;

'linear': the values from the nearest grid cells in space and time are linearly interpolated to the [date_time, latitude, longitude] coordinate of the ship

providing a number of atmospheric, land and oceanic climate variables interpolated along the five-minute cruise track.

Notes

The Antarctic Circumnavigation Expedition was made possible by funding from the Swiss Polar Institute and Ferring Pharmaceuticals. SL received funding from the Swiss Data Science Center project c17-02. This dataset was created as part of the ACE-DATA project (Swiss Data Science Center project c17-02) and contains modified Copernicus Climate Change Service information [2020].
