The 2-m air temperature anomalies at monthly intervals for 1958-2022 over Antarctica at 60 km grid spacing are reconstructed based on the methodology of Nicolas and Bromwich (2014; doi: 10.1175/JCLI-D-13-00733.1). The ERA5 global reanalysis provides the weights to spatially extrapolate the monthly mean temperature anomalies (1981-2010) from 15 fixed stations. 14 stations used by Nicolas and Bromwich are employed along with Belgrano that replaces Halley.
Complete descriptions of the variables can be found in the attached recon_readme.txt file.
