"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
"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."
"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!"

Effective 19 Apr 2021 we have released Digital Atmosphere V3.32, which contains bug fixes and improvements for the IAC/FLEET code plotting module. To get it head to our download page.
Digital Atmosphere is a full-featured Windows software package that allows you to plot detailed surface
and upper air maps, soundings, and radar charts anywhere in the world.
This software program has been under development since 1992 and is used by hundreds of hobbyists, companies, and weather agencies.
See it in action at:
MeteoCenter Russia, and
Since it can construct ultra-high resolution weather maps, it is used for graphics content in
IFR Magazine magazines.

Professional Version: $199 | Info | Buy
There's no risk getting the Standard Version, as it is upgradable at any time to the Professional Version for the difference in price.
Our popular forecast storm chase simulation was rewritten and updated in late 2014 and offers a choice of either chase simulator mode
or single-point forecasting, with extensive verification metrics.
This package lets you try your hand at forecasting on hundreds of spring days spanning 2010 to 2014 --
including big outbreaks, ordinary scenarios, and null events.
You never quite know what you'll get!
Start out perusing the morning charts. You get 140 of them each day, including SPC diagnostics and even SPC outlooks if you want to peek.
After you looked at the charts, you need to pick a starting point for your chasemobile.
Then start it on its way towards the target!
As severe weather unfolds, you'll see text reports stream in from locations close to your chasemobile. A karma rating keeps
track of how well or disappointing your chase is doing, comparing your own success and what's going on just over the horizon.
A thorough set of SPC summaries tracks how you're doing.

Do you have what it takes to get storm chasers to the target?
This educational forecasting simulation draws from 250 major chase days between 1979 and 2009, presenting users with the morning
analysis charts and high-resolution hourly satellite images.
Page forward hour by hour and refine the forecast, then once storms develop, compare how well you did with the locations of
actual tornadoes, hail, and wind.

WX-SIM is a dynamic forecast model operating at one location, forecasting the weather for that spot. WX-SIM exploits observed conditions and
centralized forecast data from NOAA and combines it with its own sophisticated physics model of the local atmosphere.
The result? A singularly accurate forecast for the location of your choice. This makes it the tool of choice for the
agricultural industry, aviation forecasters, and sporting venues.
WX-SIM Standard: $129.00 | Info | Buy
WX-SIM Professional: $249.00 | Info | Buy
We recommend the Standard version for most users. For those who would like to upgrade later, the Professional version is available for the difference in price.
We are the sole publisher of the Forecaster's Handbook Series, written by Tim Vasquez, an actual operational forecaster with 10 years
in Air Force weather and 15 years in private practice.
These are not school textbooks or scholarly works -- they are guidebooks and references for practicing meteorologists and are
perfect for not only professionals but hobbyists, broadcast meteorologists, storm chasers, pilots, flight dispatchers,
and anyone who deals with forecasting on a regular basis.
The technical level spans the entire range of intermediate to advanced in an easy-to-understand format.
Excessive introductory content and complicated math are omitted, and the concepts and examples focus squarely on actual forecast considerations,
real life cases, and those rare bits of wisdom that make or break a forecast.
And for university students, the experience distilled in these books contains valuable insight into the forecast process that simply isn't
conveyed by courses filled with emphasis on dynamics and physics.
