Global Upper Archives was introduced by Weather Graphics as the single largest collection of WMO TEMP-formatted upper air weather data in existence. This easy-to-use collection of upper-air data imports directly into programs like Digital Atmosphere, RAOB, and any other package that accepts standard "TTAA/TTBB" upper air data. Plot historical upper-air charts and soundings for almost anywhere in the world during the past several decades!

As with Global Surface Archives, you don't get cryptic XML or JSON records, a database, or some other proprietary file. All data is in plaintext ASCII and is in TEMP (TTAA/TTBB/PPBB) which is by far the most widely used upper air format in existence. This means the data can be easily plotted by Digital Atmosphere and RAOB, and works in off-the-shelf programs like GEMPAK.


Period of record: January 1945 to April 1, 2019
Frequency: Four times daily (00, 06, 12, 18Z) / Hourly starting August 2013
Formats: TEMP (WMO FM-35) upper air data ordered by date-time and collected into monthly ZIP files
Displayable as maps?: Yes - Digital Atmosphere, RAOB, GEMPAK, other programs which read upper air collectives.
Dataset size: 7 GB compressed (apprx 20 GB uncompressed)
Inventory: Listings by station and year: 1945-1972, 1973-2013 (more recent years not yet inventoried).
Data samples: 1976-01-03 1200 UTC, 1982-01-20 0000 UTC.
Documentation: For further information, see the technical manual here (PDF).
Special notes: Coverage before 1973 is limited primarily to world stations that are associated with U.S. agencies. Please check the inventory file for further info.
