The downwelling shortwave radiative fluxes were measured by an upward-looking pyranometer at the Chilean Antarctic Research Station, Professor Julio Escudero, on King George Island. The research platform at Escudero is supported by the Instituto Antártico Chileno (INACH). Yearly directories from...

These files contain hourly and daily observational data that have been quality controlled. Daily observations are from a composite of manual observations made four times per day from 01 April 1989 to 30 November 2001, adjusted 2-minute automated weather station observations from 01 December 2001...

Extreme cold temperatures were observed in July and August 2023, coinciding with the WINFLY (winter fly-in) period of mid to late August into September 2023, meaning aircraft operations into McMurdo Station and Phoenix Airfield were adversely impacted. Specifically, with temperatures below −50°C,...

The 30-year-long bias-corrected monthly mean surface air temperature data from historical automatic weather stations (AWSs) at Mizuho, Relay Station, and Dome Fuji, is available online at https://doi.org/10.17592/002.2025010413. Nonetheless, these data are not continuous records and some months...

This is a map and data of all known Automatic Weather Stations operating in the Antarctic. Information for these maps and data are voluntarily provided by the operators. Collaborative sites are denoted in the legend.
