EPA AERMOD · in your browser
Run the full EPA chain (AERMET, AERMAP, AERSURFACE, BPIPPRM, and AERMOD) from any browser, on any laptop. No workstation to buy or maintain, no dongle. Big NAAQS runs split across the cloud and finish in minutes, several at once, and every result is byte-for-byte identical to EPA’s reference model.
A real PM₂.₅ NAAQS run, start to finish; no install, nothing to configure by hand.
Don’t take our word for it. Every EPA test case runs on the platform and matches the published reference output: design values and every receptor. Read the AERMOD 26135 validation report →
13 source types, 5 criteria pollutants plus HAPs, NO₂ chemistry (ARM2 / OLM / PVMRM / GRSM / TTRM), flat and complex terrain, building downwash; all of it, with nothing to install and always the current EPA version.
Runs entirely in the cloud, opened from any browser on any laptop; no modeling machine to buy or keep patched, and no license dongle. Your computer does nothing but show the results.
A five-year NAAQS run over a thousand receptors is split across dozens of machines and finishes in minutes. Start several projects at once; they run side by side, and keep going even if you close the tab.
We rank the nearest surface stations by distance and flag each Defensible or Requires-justification, already processed through AERMET, with terrain and downwash handled for you. No chasing raw data, no preprocessing by hand.
Concentration contours on a real basemap, an instant NAAQS pass/fail, and source culpability; then one click produces the submission ZIP: the EPA-allowlisted files, sha256 checksums, and version pins, exactly what you attach to the application.
Export everything: inputs, outputs, the raw .inp. No lock-in.
Every number on the results page is parsed from the run’s actual output, not re-derived.
Each account’s projects and runs are sealed off, verified end to end.
Every project is pinned to its AERMOD version (26135 current); a re-run today matches the run of record.
