Antarctic Daily Mesoscale Air Temperature Dataset Derived from Remotely Sensed Land and Ice Surface Temperature – AntAir ICE
AntAir ICE is an air temperature dataset for terrestrial Antarctica, the ice shelves, and the seasonal sea ice around Antarctica in a 1km2 spatial grid resolution and a daily temporal resolution available from 2003-2021. AntAir ICE was produced by modelling air temperature from MODIS ice surface temperature and land surface temperature using linear models. In-situ measurements of air temperature from 117 Automatic Weather Stations were used as the response variable. Each day has a bricked spatial raster with two layers, saved as a GeoTIFF format and in the Antarctic Polar Stereographic projection (EPSG 3031). The first layer is the predicted near surface air temperature for that day in degree Celsius * 10 and the second layer is the number of available MODIS scenes for that day ranging from 0 to 4. Areas with cloud contamination or without sea ice are marked with no data. Files for each year (2003-2021) are compressed with a ZIP files for each quarter.
Python 3.8 was used for conversion of the MODIS products from HDF files to raster and all data handling and processing was thereafter done in R version 4.0.0. All data processing and modelling procedures are available as R scripts on a public Github repository: https://github.com/evabendix/AntAir-ICE. Using this code it is possible to download new available MODIS LST and IST scenes and apply the model to continue the near-surface air temperature dataset.

- Supplemental Information
- The dataset is in a GeoTIFF format and in the Antarctic Polar Stereographic projection (EPSG 3031) with one file per day. Each day is a bricked spatial raster with two layers; the first layer is the predicted near surface air temperature for that day in degree Celsius using a scaling factor of 0.1, the second layer is the number of available MODIS scenes for each grid cell for that day ranging from 0 to 4. Areas with cloud contamination or without sea ice are marked with no data. The files are names AntAir_ICE_<YYYY>_<DOY>.tif, where <YYYY> represents the year and <DOY> represents the day of year. Files for each year (2003-2021) are divided into quarters with January, February, March as 1, April, May, June as 2, July, August, September as 3 and October, November, December as 4 and compressed to ZIP files.
