The Reader three-hourly observation data are composed of the nearest valid instantaneous observation within 40 minutes of the synoptic reporting times (i.e., 00, 03, 06, 09, 12, 15, 18, and 21). These data are uncorrected for the years 1980-1990, gross error checked for 1991-2000, and quality...

These files contain monthly text-based observational data that is made available by automatic weather stations (AWS) maintained by the McMurdo Weather Office at McMurdo Station, Ross Island, Antarctica.. The files contain a three-line header with the name of the AWS, its ID number, Location...

These files contain instantaneous observations at ten-minute intervals, with either six or eight columns. The data have been taken directly from the originally transmitted hexadecimal data with only gross error checking during the processing. There will still be bad data points that are within...

Radiosonde data is available from Amundsen-Scott South Pole Station. The following files are ASCII text with slight variations in their convention over the record: aYYMM.1st (1977-1990) MMYY.aud (1991-2004) MMDDTTTT.dat/DAT (1993-2004) MMDDTTTT.gps/dat, and a few MMYY.aud (2002-2004)...

Each data file follows the naming convention YYMMDDTHHMMSS.txt where YY = Year MM = Month DD = Day T = Tide HH = Hour (UTC) MM = Minute SS = Second There are few times over the history of this data where order of the columns change. These correspond with when instruments were changed out for the...

Each yearly directory contains monthly CLIMAT messages in ASCII text format. Wind speeds and gusts had to be corrected between 2/28/2019 17:56 UTC - 11/20/2019 16:17 UTC due to the wrong propeller being installed on the BASE wind sensor. All files with "_fix" appended to them have been corrected....

These data should not be used for scientific analyses. The pump system that carries seawater to the waterwall instrument has had multiple intakes at different depths which can cause unexpected variations in the data that are not representative of the environment. These issues are under evaluation...

Through 2016, all Snowstake measurements were made from a single Snowstake located between the Aquariums and the Pump House. A measurement was made once a day. Due to the location near the decking, snow may have been shoveled onto the Snowstake. A had rail on the deck was used to determine New...
