CUSTOMER COMMENTS

"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
Weather Consultancy Services, UK

"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



Storm Forecast Simulator

Forecast trainer & severe weather data archive

Can you get your chasers to the storm?


Incredibly detailed charts going back as far as 1979!


If you don't want a random case, select from the dropdown list of events.


There's upper level charts for 250, 500, 700, and 850 mb.


And there's the all-critical SKEW-T diagrams.


At least 50 storm chasers will be trying to figure out whether to head out the door or stay home, and a lot of it will hinge on the outlooks and products you release.


Don't issue a tornado watch on a bust day, or the chasers will be pretty ticked off!


All storm dates contain a narrative summary and forecast discussion so you can compare notes.

Storm Forecast Simulator is a forecast training system containing 232 of the biggest chase days in severe weather history! Watch the day unfold, issue an SPC risk area and a severe weather watch if warranted, and as the day continues you'll see 50 simulated chasers react and target the forecast area. Graphics for all days have been equalized to a common format so that it's difficult even for an experienced forecaster to tell whether a case date is for 1983 or 2003!

Storm Forecast Simulator features
* 18,700 graphic products for 232 storm dates in 1979-2009. Any of them may be printed, exported, or copied to the clipboard. Best of all they're in GIF and JPG format so you don't even need to install Forecast Simulator -- just browse them with your favorite graphics viewer!
* Full 1 km high-resolution visible satellite imagery, every hour, for ALL chase days. It doesn't matter if it's 1979 or 2009 -- you have crisp, high-resolution satellite imagery! Much of this data came from NCDC data recovery delivered to us on IBM Ultrium cartridges and has never been viewed since the original storm date!
* Hourly surface charts, 12Z and 00Z upper air charts, and 12Z and 00Z soundings are provided for all case dates to help you work on your diagnostic skills.
* Surface and satellite data can be easily animated to see how conditions are changing over time.
* Time progression system ensures that you progress through a chase day hour by hour, limited only to those products available at that hour. There's no way to "sneak a peek" ahead at future hours until you're ready.
* Chaser success is evaluated continuously using hourly SPC plots of severe weather. See whether your chasers are missing the action or capturing great photographs.
* Hidden date feature, if turned on, ensures that you begin a new case without the slightest idea of what you're looking at. All dates are obscured, and we've even gone through pains to obfuscate the position of upper air sites that relocated in the 1990s (a clue experienced forecasters often are well-aware of). You can even narrow the random case selection down by weather regime type, significance, and range of years.
* If you don't want to run the Storm Forecast Simulator, you don't have to! All images are in standard GIF and JPG format, sorted by date, for viewing with your favorite graphics program.
* Significant storm dates are limited to the Great Plains. Sorry, no coverage of New York supercells or Michigan tornadoes, though we may release an expansion set at a future date.
