For months with available temperature observations from Byrd, the monthly mean temperature values are calculated from 6-hourly observations and—to a lesser extent and only for the 1957-1975—from daily minimum/maximum temperatures.

The sources of the observations are as follows: - For 1957-1975, the 6-hourly data are taken from the Integrated Surface Hourly Data set (DS 3505), and the daily minima/maxima are taken from the Global Historical Climatology Network-Daily Data Set (GHCN-Daily). - From 1980 onward (the Byrd AWS era), the observations are originally from the Antarctic Meteorological Research Center (AMRC) at the University of Wisconsin-Madison, responsible for running the Antarctic AWS Program.

For our dataset, we use the monthly mean temperatures computed by the Antarctic READER project from the observations provided by the AMRC.
