What’s Happening Now

A great big thanks to all the State staff who joined us for the NESCAUM-sponsored AERMOD training in Albany last month. The weather was cold, but the hospitality was really warm!

2018 Holiday Quiz Answers

Thanks to everyone who participated in our 2018 Holiday Quiz. We hope you enjoyed it, and maybe laughed at some of the wrong answers. With no further ado, here are the answers:

1. Much was discussed over the last couple of years regarding EPA’s updating Appendix W to 40 CFR 51. A commonly used acronym for this document is GAQM. What does GAQM stand for?

c. Guideline on Air Quality Models

2. The best air quality modeling software is

e. C and D

(either answer is acceptable ☺)

3. What capability does AERSCREEN have that AERMOD does not?

b. Fumigation calculations

4. BeestXpress is Providence/Oris’ high-speed AERMOD modeling system. How does BeestXpress speed up your AERMOD run?

c. The large DTA file is partitioned into a user-defined number of smaller DTA files, each of which runs on its own core/processor

5. AERMOD Wizard is a brand new software product being released by Providence/Oris. If you read our July – November newsletters, you’ll know that AERMOD Wizard can do these tasks:

f. All of the above (yes, all of the above!)

Congratulations to the winners, who will be receiving their very own Go BEEST Mode t-shirt!

EPA News

With the Federal Government (and consequently US EPA) being shut down for most of January, we have no new EPA news items to share with you.

As we mentioned in December, EPA has come up with a workaround regarding obtaining land cover data and NED data in GeoTIFF format. See We presented a webinar about obtaining NED data on January 31. Click here to view the video for the webinar.

Simply the Best!


BEEST 11.13 is out! This new version includes:

  • Ability to Find “Other” objects within Show Current Data Graphically
  • An updated Import KML tool
  • Displays a message when a met station’s profile base elevation is not in the EPA database
  • Several bug fixes

*AND* BEEST 11.13 includes our new Lidar Calculator, a tool that helps you obtain heights for buildings and tanks based on airborne downward-looking Lidar data.

We presented a webinar on January 29 about the new features found in BEEST 11.13 *and* our new Lidar Calculator. Click here to view the video for the webinar.

As always, users in maintenance can download the most recent version of BEEST from Support → Software Updates.

“Go BEEST Mode!” — What? You still don’t have your own “Go BEEST Mode” t-shirt? Don’t worry, we’ve got plenty left – so email your request to and receive your very own “Go BEEST Mode” T-shirt! You’ll be the envy of modelers everywhere!

AerScreen for Windows

Since AerScreen for Windows uses both AERMOD and AERMAP, we released AerScreen for Windows 3.06 on May 31, 2018. This new version fully supports AERMOD 18081 and AERMAP 18081.

Users in maintenance can download the most recent version of AerScreen for Windows from Support → Software Updates.

Professional CalPuff

Our most recent version of Professional CalPuff (4.00) was released August 26, 2016 and is available to all registered users with current maintenance.

Users in maintenance can download the most recent version of Professional CalPuff from Support → Software Updates.


AERMOD Wizard 1.00 is here! We think that this handy tool will be a game changer and so will you! Imagine being able to download ambient data and creating a temporally varying AERMOD-ready background file with just a few clicks! Or what about being able to do multiple Q/D analyses with just a few clicks? Or building wind roses and/or pollutant roses and be able to export them to Google Earth – also with just a few clicks? That’s not all this amazing tool can do, so go here to get your own copy of AERMOD Wizard.

We presented our AERMOD Wizard kick-off webinar on February 5. We demonstrated all the current features of this awesome new utility. If you missed it, click here to view the video for the webinar.

*We’re off to see the Wizard!*

If you have suggestions for an enhancement to any of our modeling software products, please let us know and we’ll do our best to incorporate it into the software ASAP!

AERMOD Modeling for Permits

Our first scheduled AERMOD Modeling for Permits class for 2019 will be February 26‑27 in Austin, Texas. Register today and plan to join us in the Live Music Capital of the World! Click here to register!

Advanced AERMOD

Similarly, our first scheduled Advanced AERMOD class of 2019 is going to be February 28‑March 1, also in Austin.

Advanced AERMOD covers those topics that are near and dear to modelers, such as:

  • NAAQS modeling for 1-hour NO2, 1-hour SO2 and 24-hour PM2.5 (including MaxDCont Viewer)
  • Meteorological data processing with AERMET / AERMINUTE / AERSURFACE
  • Changes related to the new Appendix W (Guideline on Air Quality Models)
  • MAXIFILE and ARRAY2 processing
  • AERMOD alpha options, such as PSDCREDIT
  • AERMOD Wizard and its uses

AERMOD Modeling for Permits August 20 – 21 Austin, TX
Advanced AERMOD August 22 – 23 Austin, TX
AERMOD Modeling for Permits December 3 – 4 Austin, TX

**Don’t forget, if our schedule of classes doesn’t mesh with your schedule, or if you have several people that need to be trained at once, contact us about setting up an on-site class. Have laptop, will travel!**


**BeestXpress has been upgraded to run AERMOD 18081**

In addition, BeestXpress users have some great system enhancements to work with:

  • The “Job Details” webpage now displays the pollutant being modeled;
  • The “Job Details” webpage now displays run progress for MAXDCONT calculations;
  • Modeling runs with multiple partitions now include a combined AERMOD input file (*.DTA) in the output .ZIP file;
  • Added an option to the “Submit Job” webpage that affects modeling runs with multiple partitions: the intermediate output files created by each partition can be omitted from the output .ZIP file
  • The “Job Search” webpage now includes the option to search by project number
  • Users have access to up to 50 partitions per AERMOD run

To date, BeestXpress has processed over 300,000 AERMOD runs. Wow!

If you’ve never used BeestXpress, or it has been a while since you did, you may want to log on at to take advantage of our AERMOD “force multiplier”. That AERMOD run that might have taken a day to run on your desktop computer can finish in an hour or less on BeestXpress. When time is money, BeestXpress is the best modeling return on investment there is!

Meteorological Data Processing Services

Do you need AERMOD-ready or CalPuff-ready meteorological data? If so, we can help! Whether it’s running the AERMET / AERMINUTE system or a full CalMet run, Providence has the background, know-how, and experience to have your data processed and ready for you ASAP. Need on-site data processed? We do that, too! If you’d like more information, contact us at or

Consulting Solutions

One thing that we’re very proud of is the depth and range of our modeling experience and expertise. The kinds of air quality models we’ve used include all types, ranging from simple screening tools like SCREEN3 and AERSCREEN to plume models like ISC and AERMOD to CalPuff to CAMx. The types of analyses included basic Significant Impact Level, NAAQS, PSD increment consumption, Class I analyses, air toxics, and SIP attainment demonstrations. Most recently, we have begun conducting nonattainment permit inter-pollutant trading (NOx for VOC) modeling using CAMx. So, we’ve seen it all. To that end, should you or your clients need additional modeling assistance or just a second set of eyes to QA or peer review your modeling (ranging from initial protocol up to final submission), we stand ready to help.
