The downwelling longwave radiative fluxes were measured by an upward-looking pyrgeometer 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 2017/12/14 – 2023/08/17 contain monthly comma separated variable (csv) files that start at 03:01 UTC on the first of each month.

File name: esc_lwdYYMMDD_HHmm.csv, where esc stands for Escudero, and lwd stands for longwave downwelling.

Columns, which are given in the file headers, are: Date (YYYY-MM-DD), Time (HH:mm:SS), number of samples (#Samples), Status (generally blank), Radiation in W m-2, Temperature in K, and Power.
