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 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."
