"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."
"The quality of your products is second to none."
— C. Brian Batey

"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."

— 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."
"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!"
