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

Upgrade Page

If you are simply looking to upgrade from STANDARD to PROFESSIONAL version and your Standard registration is still valid, you may do that for the difference in price. Click the link below to do so.

Replace your Standard version with the Professional version
If you own a current Standard version, just click this link to upgrade. We will email you the download information when we process your order (please allow 2 business days).

As Weather Graphics is a very small business serving a niche market, we rely on upgrade pricing to help fund continued development work. The registration for all Digital Atmosphere customers is considered to be either current or expired. To find out what your status is, either contact us or check your receipt from your last paid upgrade or last paid registration. If it was purchased within the last four years then your status is current. Otherwise your status is expired, even if you obtained a free upgrade recently.

Which services are you entitled to? This depends on your registration status.

  • Registration is current. If your registration is current, you will receive the full range of service and support. If new versions of Digital Atmosphere are released after your most recent paid registration, you may obtain a provisional upgrade. This is a complimentary upgrade beyond the version you originally purchased, under the condition that we will provide it and support it only if your registration is current.

  • Registration is expired. Keys will be provided to you for the version you obtained during your last paid registration or last paid upgrade. Your provisional upgrades become void and no further keys can be provided for them. Support will be provided to the best extent that we can, though we may be unable to answer questions about old versions since the programming may have changed significantly and the older versions cannot be tested or diagnosed.

By purchasing an upgrade, your registration will be renewed and you will be entitled to full service and support another four years.
