aqmis header

AQMIS SaaS is the next generation air quality management solution that enables you to immediately begin analyzing, visualizing, and reporting your ambient air monitoring data.

Why develop an ambient air monitoring software application from scratch when you can simply import your monitoring data into our proven AQMIS SaaS solution?


  1. Automated import of EPAs ambient air monitoring network
  2. Begin analyzing ambient air quality data today
  3. Automated comparison of modeled versus measured
  4. Pollution rose to help identify contributing sources
  5. Automated exceedance detection of ambient air quality standards
  6. Forecast air quality including Air Quality Indicators (AQI) using AI – Deep Neural Networks (DNN)

Together, these benefits result in significant time and cost savings!

AQMIS SaaS is used by regulatory agencies, industry, consultants, environmental interest groups, and the public.

Guideline on Air Quality Models” Conference Wrap-Up

A&WMA logo  

Lakes Environmental was proud to be a gold sponsor of the recent Air & Waste Management Specialty Conference “Guideline on Air Quality Models: Developing the Future” planned by the Atmospheric Modeling and Meteorology Committee (APM) of the A&WMA Technical Council. The conference was held September 13-15, 2022, at the Sheraton Imperial Hotel in Raleigh, North Carolina. Approximately 100 people attended the conference, and we enjoyed meeting many of the attendees!

Nearly 40 presentations were given with topics covering AERMOD evaluation and validation, NO2 modeling techniques, building downwash updates, innovative modeling techniques, use of prognostic meteorology, and other modeling topics. The conference also featured a Keynote session devoted to presentations by EPA’s Office Air Quality Planning and Standards (OAQPS) Air Quality Modeling Group.

Our own Michael Hammer was the general conference chair and also presented, “Sensitivity Study of the CALPUFF Modeling System to Data Resolution in the Weather Research & Forecasting (WRF) Model”, a paper he co-wrote with Dr. Jesse Thé and members of the British Columbia Ministry of Environment and Climate Change Strategy. The presentation looked at the impacts of changing model resolution in the WRF meteorological model and CALPUFF modeling system.

File Changes with AERMET 22112

Lakes Environmental recently released the new AERMOD View Version 11.0 which includes support for the latest U.S. EPA model releases dated 22112 for the AERMOD & AERMET dispersion modeling components. The AERMET 22112 update debuts an entirely new code-base for the regulatory meteorological preprocessor. As illustrated below, the new AERMET has been changed from a three-stage to a two-stage process.

With internal routines reconfigured for extracting data, performing quality assurance, and calculating boundary layer parameters, AERMET View Version 11.0 includes some file formatting changes. When running AERMET 22112 in AERMET View Version 11.0, look for the following:

  • Instead of 3 separate input files (*.IN1, *.IN2, *.IN3), the application will create a single combined-stage input file with extension *.INP.
  • Message and Report files are similarly contained in single stage outputs files. Messages will be written to the *.MG file while Report output will be written to the *.RP file.
  • The model still produces the same surface (*.SFC) and profile (*.PFL) output files for use in AERMOD.

The image below shows how files appear in the new Tutorial project that accompanies AERMET View (found in the C:\Lakes\AERMOD View\Tutorial\AERMET\ file folder).

Of course, AERMET View remains backwards-compatible with all previous releases dating back to 12345 (December 2012). Simply go to the File | Preferences settings and choose a different version of AERMET form the drop-down menu.
