CUSTOMER COMMENTS

"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

Weather Map Handbook
a guide to the Internet, modern forecasting, and weather technology

SECOND EDITION

by Tim Vasquez
2008 / 169 pp. / $29.95 / ISBN 0-9706840-7-X
8 x 10" / True bound / Offset print / Glossy color cover


It's the meteorology handbook that forecasters have been waiting for. It brings a focus on graphics, not on concepts and obscure equations. It's the type of book designed to get beaten up and torn with frequent use at your analysis desk. The Weather Map Handbook explains nearly every chart used in meteorology. It's designed for the Internet, showing where the "pros" go to get their charts. It has a complete listing of weather map symbols, iconographs, and decoding information. It's the perfect companion to our other major title, Weather Forecasting Handbook.

The science of forecasting has not changed, but the Internet and new marvels of technology have completely redefined the process. It is not a rare thing for weather hobbyists and National Weather Service forecasters to get a product from the very same site. With more and more charts and tools appearing on the Internet by the week, how do you make sense of the avalanche of weather imagery and data?

Using a double-page format, the Weather Map Handbook demonstrates nearly every type of weather map, image, and product in common use. An overview of each item’s origin, purpose, shortfalls, and tips are outlined. Standards for analysis symbology and chart markings are summarized. The surface, 850 mb, 700 mb, 500 mb, and 300-200 mb charts get two pages each, complete with philosophy, objectives, and techniques for each chart. Thickness, isentropic, and Q vector products get their own sections.

The WSR-88D Doppler Radar, in use by the United States weather services, has played a vast part in the weather information revolution. In the Weather Map Handbook, it gets thirty pages packed with the fundamentals and algorithms of the WSR-88D. Much of this information is obscure and nearly impossible to find. From the workings of the Composite Reflectivity product to the exact process used by the Mesocyclone Detection Algorithm to deconstruct a radar scan, any NEXRAD radar product on the Internet can be understood. There is even a range-height nomogram for each volume coverage pattern.

From the Eta to the MM5, from the GFS to the GEM, each numerical forecast model is revealed in incredible detail. Ensemble forecasts are highlighted. The satellite chapter explains visible, infrared, and water vapor imagery, how it is created, and how to interpret it. Even the METAR, TAF, SYNOP, and radiosonde formats get their own sections, complete with decoding instructions.

Topping off the book is an appendix with surface and upper-level station plot models, a vast technical glossary compiled from the depths of the NWS, SPC, and NCEP, and much more! Whether you are a hobbyist, private forecaster, a professional, or a student, the Weather Map Handbook is the book you can’t be without.
