Dataset abstract This dataset contains a mask for the identification of cold and warm temperature advection along the Antarctic Circumnavigation Expedition (ACE) track based on a simple method using the difference between the sea surface and air temperature. This mask is a combination of measured air temperature during ACE and sea surface temperature fields from ECMWF operational analysis data.
