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)...

South Pole Station's one-minute surface observations that contain wind direction, wind speed, temperature, dew point, altimeter reading, and sea level pressure data. These are produced on a minute by minute basis. The file naming scheme is OMO MM-DD-YY.txt where OMO denotes one-minute...

These files contain monthly observational data that have been quality-controlled using semi-automated computer programs as well as oversight by our staff. The filenames are prefixed with a label identifying one of three different observation intervals - ten minute (10min), one hour (1hr), and...

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...

Monthly 3 hourly (.prn) (1957-2006) and daily 1 hourly data (.csv) (1957-2007) are available. The column labels are: Station ID (Station_ID), Date and time (Date_Obs), temperature (T;DegC), maximum temperature (Tmax;DegC), minimum temperature (Tmin;DegC), Sea level pressure (PPPP), Station...

Synoptic observations were made at Amundsen-Scott South Pole Station. A document referencing cloud and observation formats in synoptic messages is included. The following files are ASCII text with slight variations in their convention over the record: MMDD.SYN (1992-1999) MMDD.syn (1999-present)

Each yearly directory contains monthly CLIMAT messages in ASCII text format. File name conventions: MMM YYY UA CLIMAT.txt (2004-2009) MMM YYY UA CLIMAT.TXT (2004-2009) MMM_YYYY_UA_CLIMAT.txt (2009-present)

An automated system (currently FMQ-23) is utilized, but all of the visual observation elements (visibility, present weather/precipitation, and sky cover) are taken manually. All automatic data from the two FMQ towers, located at the skiway and the Clean Air Sector, is received via Mesotech’s...

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...

AnnualWeatherSumYY.docx (2022-present) A text document with a written summary of each month throughout the year noting any particular monthly records, trends, and general overview of the month’s weather

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...

File name convention: NZSPMMYY.txt (2001-present), NZIRMMYY.txt (2002-2003) The column labels are: Day Time Temperature (Temp;DegC) Pressure (Pres; mb) Altimeter (Alt;inHg) Sea level pressure (Sea;mb) Wind speed (Speed;kts) Wind direction (Dir;T) Wind gust (Gust;kts) Peak wind (Peak;kts) Minimum...

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...

These files are CLIMAT surface messages, created from a subset of AWS sites from the UW-Madison AWS network. The filenames are named [III]-[YYYY]-[MM].txt, where III is the three-letter code to indicate the station, YYYY is the year, and MM is the month. These files are formatted per the World...
