AERMOD modelling support
Practical, auditable, regulator-ready assistance
Focused exclusively on the U.S. EPA AERMOD modelling system and its companions (AERMET, AERMAP, BPIPPRM). We offer targeted engagement - run-ready inputs, independent peer review, short troubleshooting sessions and confidential technical backup on request.
Our support approach
Envitrans is software-first. We publish environmental modelling software and model-ready datasets - and provide targeted technical support to help teams use those tools effectively. Our role is to enable your team, not replace it. We work behind the scenes, on request, to clear technical hurdles, ensure data integrity and deliver auditable, regulator-ready outputs.
Practical expertise
We build the tools and apply them in projects - so our guidance is pragmatic, tested and immediately usable.
Targeted support
We step in where you need help - troubleshooting, input-file review, run-ready setups and smoke tests.
Data integrity first
Clean meteorological and GIS inputs reduce rework and speed regulator acceptance.
Transparent handover
Deliverables include versioned files, documentation and clear change logs - so your team retains ownership.

Why Envitrans
Publisher + practitioner
We build the software and also apply it in real projects. That combination means faster setup, fewer mistakes, and practical outputs your team can run with.
Targeted support
Not every project needs full outsourcing. We step in where it matters most - troubleshooting, input-file reviews, run-ready setups, and smoke tests. You stay in control; we clear the hurdles.
Data-driven delivery
Robust meteorological and GIS data pipelines are at the core of our work. By keeping inputs clean from the start, we reduce rework and keep projects moving.
Auditable and defensible
Every handover includes documentation, version control, and clear change logs - so your team has confidence in what's delivered and how it was built.
FAQ
Do you provide regulator sign-off?
No. Regulator engagement or authorised signatory services are out of scope unless separately agreed. We prepare submission-ready outputs but do not act as the authorised signatory by default.
Do you supply met datasets?
We process client-supplied meteorology and can provide model-ready datasets. Provision of third-party raw data is available by separate agreement.
Can you remain behind the scenes?
Yes. We routinely provide discreet, behind-the-scenes technical support so your team retains client-facing control.
