What’s Happening Now

EPA News

New AERSURFACE – EPA has released a new version of AERSURFACE (20060). This version has the ability to read and process 2001, 2006, 2011, and 2016 National Land Cover Database files. It can also supplement this with impervious cover and tree canopy cover, where available. You can read more about it on SCRAM.

On June 15, 2020 EPA held a stakeholder webinar on AERSURFACE 20060. If you missed it, you can see the webinar slides here.

Our next version of BEEST (12.04) includes AERSURFACE 20060.

Conferences and Workshops

Here’s the latest on conferences and workshops…

As you might imagine, face to face meetings and conferences are going to be rare, if not non-existent, for the near future. In addition, given the somewhat fluid nature of the times we live in, we encourage you to check organizations’ websites to find out the latest on upcoming conferences and workshops.

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 info@providenceoris.com, and we’ll be happy to include it.

Simply the Best!

"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 info@providenceoris.com and receive your very own "Go BEEST Mode" T-shirt! You’ll be the envy of modelers everywhere!

Who knows – maybe you could turn a "Go BEEST Mode" t-shirt into a nifty "Go BEEST Mode" face mask?

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!

“Our expertise is contagious. Catch it!”

Beginning with our September 2020 AERMOD classes, a new course fee pricing structure goes into effect. If a student registers more than one month before the start of class, the course fee is still $995. If a student registers less than one month prior to the start of class, the fee is $1,095 per student. As before, if more than one student from an office/company registers for a class, each registered student has a $100 discount applied to the course fee. Other discounts, such as those for government air agency staff, are still available.

AERMOD Modeling for Permits

Our next scheduled AERMOD Modeling for Permits class will be September 15-16, 2020 and is an on-line class. Sign up today and plan to join us in the virtual world. If you want to register, click here.

Advanced AERMOD

Similarly, our next scheduled Advanced AERMOD class will be September 17-18, 2020 and is also on-line.

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

2020 Class Schedule

The rest of our scheduled classes for 2020 are:

Class Dates
AERMOD Modeling for Permits December 1-2, 2020
Advanced AERMOD December 3-4, 2020



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 400,000 AERMOD runs.

If you’ve never used BeestXpress, or it has been a while since you did, you may want to log on at www.beestxpress.com 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 info@providenceoris.com or jamesred@providenceeng.com.

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. Feel free to contact us at (512) 258-8855 or info@providenceoris.com.
