Your source for forecasting tools, software, and books since 1993

"Thank you for actually penning these books. They are a wonderful review of the concepts without the excessive (but necessary) amount of math behind them. I wish they had been recommended as supplements in both my undergrad and graduate years."

— Josh Tobias, 2017

"I have used Digital Atmosphere for quite sometime and consider it to be one of the most straightforward, comprehensive, and operationally useful programs on my server. I have found it to be invaluable for my day-to-day analyses and forecasting as well as my ongoing research. Tim is also extremely helpful and absolutely indispensable when it comes to locating scripts, the best datasets, and even professional contacts to help make any organization as productive as possible."

Chris Robbins, iWeatherNet

"The quality of your products is second to none."

— C. Brian Batey

"Thanks Tim for your quick response (we like that at FedEx) about our Professional Versions! As we're a 24/7 operation, we're look forward to augmenting our present weather system with Digital Atmosphere."

— Mel Bradley, FedEx Operations

"Wow. Your books are incredibly technical and useful. I consider myself a very amateur weather watcher and feel that I am already ahead of the curve. Thank you."

— Terry W. Taylor

"The NEXRAD support is truly awesome and easy to use - and the other feature just really tops it off. This is about my sixth email tonight - the other five being to other spotters in the area telling them they just have to download Digital Atmosphere and give it a serious going over."

— David Cashion

"I'm really looking forward to the next phase of Digital Atmosphere Workstation. I'm sure it will be as excellent as all your other products."

— Simon Keeling

"I run and manage a number of festival type events and Digital Atmosphere is able to produce charts that I can use for normal weather forecasting with a fair degree of accuracy and in particular wind speed and direction that is crucial to many of events."

— Robert Connolly, GI7IVX

"The archive data arrived today. WOW! What an amazing set of data! Thanks again for all the extras that you included as well!"

— Bryan Bollman, IA

"We do run GEMPAK and all the Unidata software also, but your package has numerous advantages, the biggest being Windows."

— Anonymous

"I am very impressed with what you have done. I have already shown several people at work your site. I plan on talking to our MIC [Meteorologist In Charge] soon to see if we can get Digital Atmosphere in the office to complement/supplement AWIPS."

— Ken Simosko, NWS, Pocatello

"This new version is even better than the older version which was awesome! Your programming skills and met knowledge amaze me!"

— Chris Kincaid

Global Upper Archives

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.
