What’s Happening Now

Major shout-out to all of our NESCAUM friends who attended last month’s Advanced AERMOD class! We had a great time and hope you did, too.

EPA News

12th Conference on Air Quality Models – EPA has posted the presentations from this triennial conference and they can be found here. The comment period for the conference will remain open until November 4, 2019.

New BPIP-Prime – As we mentioned last month, EPA released a new *draft* version of the Building Profile Input Program for PRIME (BPIP-Prime), called 19191_DRFT. This version is released for testing and evaluation and may not be used for regulatory purposes. 19191_DRFT was released to facilitate testing and evaluation of the ALPHA options associated with building downwash that were incorporated into AERMOD version 19191 (AWMADWNW and ORD_DWNW). EPA is asking the user community to submit any informal written comments to the agency (Clint Tillerson) by November 4, 2019.

Conferences and Workshops

**HOT** CAPCA Fall Technical Workshop and Forum – The Carolinas Air Pollution Control Association’s (CAPCA’s) Fall Technical Workshop and Forum will be held October 23‑25, 2019 at the Hilton Myrtle Beach Resort in Myrtle Beach, SC. For more information on this event, including registration, click here.

**HOT** AWMA Pacific Northwest International Section Annual Conference – The 59th Annual Conference of the Pacific Northwest International Section of the Air & Waste Management Association is scheduled for October 23-25, 2019, at Fairmont Hot Springs Resort, which is located near Butte, Montana. Click here for more information.

100th Annual Meeting of the American Meteorological Society – This centennial meeting of the AMS will be held January 12-16, 2020 in Boston, MA. Of special interest to us in the modeling business is the 21st Joint Conference on the Applications of Air Pollution Meteorology with the A&WMA, which is being held as one of the conferences during the annual meeting. Topics of interest in this joint conference include Advancements and Needs in Dispersion Modeling, Modeling and Monitoring of Air Pollution in the Urban Environment, Measurements and Standards in Air Pollution Meteorology, Modeling of Other Complex Air Pollution Meteorological Phenomena, and more! For more information on the annual meeting click here and for more information of the 21st joint conference with AWMA click here.

If your company, organization, agency, State, etc. has an upcoming modeling or air quality-related event and you’d like it publicized in Providence/Oris Notes, please send that information to us at, and we’ll be happy to include it.

Simply the Best!


BEEST 12.00 is now out and includes these updates:

  • AERMOD 19191 and AERMET 19191
  • Updated website link for downloading terrain data

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

Look for BEEST 12.01 to be released within the next month.

"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 AERMOD, we will be releasing AerScreen for Windows 4.00 later this month. Version 4.00 will fully support AERMOD 19191 and will also include an updated website link for downloading terrain data.

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 on 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 1.02 is now here! It includes these enhancements:

  • Support for downloading EPA ambient data published in May 2019
  • Ability to generate forward and backward trajectories from AERMET-generated SFC data
  • Support for processing monitoring data for 3-hour SO2, annual NO2 and annual PM2.5
  • Full support for AERMET 19191

We will be presenting a free webinar on AERMOD Wizard 1.02 on October 22, 2019 at 3 pm CDT. Click here to sign up for the webinar.

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

Check AERMOD Wizard out here and get your own copy.

*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 last scheduled AERMOD Modeling for Permits class for 2019 will be December 3‑4 in Austin, TX. Register today and plan to join us in the Live Music Capital of the World. Click here to register!

Advanced AERMOD

Similarly, our last scheduled Advanced AERMOD class for 2019 is going to be December 5‑6, 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

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 350,000 AERMOD runs.

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!

BeestXpress has been updated to run AERMOD 19191.

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.
