"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

"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

Frontal bulletins fix

On July 10, 2018, NOAA Weather Prediction Center changed the URL (internet address) for the NCEP frontal bulletin from http to https. Digital Atmosphere will not handle https sources until we complete internal modifications to the ingest code.

Weather Graphics has begun permanently mirroring the frontal bulletin products at a standard http address, ensuring permanent compatibility with all versions of Digital Atmosphere. To use data from this new source, there are two ways to fix any version of Digital Atmosphere, as follows:

Method #1 (for all users; takes a few minutes of manual work)

1. Run Digital Atmosphere.

2. Go to Data > Retrieve Data. NOTE: Do NOT use "Update Internet table"; this code is not active at this time.

3. In the list, scroll down to "High-res frontal bulletins" and highlight it.

4. Click "Edit Site".

5. Under "Enter URL for this site" change:

6. Click OK.

7. In the list, scroll down to "Low-res frontal bulletins" and highlight it.

8. Click "Edit Site".

9. Under "Enter URL for this site" change:

10. Click OK.

11. Click Exit. All updates are complete.

Method #2 (for advanced users; provides a perfect replacement)

1. Determine your Digital Atmosphere working directory. This can be found in Help > About.

2. Right-click on this link: digatmos.urx and choose "Save link as". Save the file to the Digital Atmosphere working directory, ensuring it overwrites the old file.

3. If you were not prompted to overwrite the file, this may mean it was saved in the wrong location, or the browser was set to ignore overwrites, or the browser is adjusting the link name without your permission (some browsers like Chrome, IE, and Edge are known to do this). Test Digital Atmosphere frontal bulletin plotting for proper function and if it still doesn't work, try again or proceed to Method #1.

These changes will be incorporated into the next updates starting with V3.07. No date has been scheduled yet for the release of V3.07.
