Why Cumulus

Built for real regulatory modeling workflows

Cumulus brings cloud-based speed, simpler project management, and report generation to the AERMOD process while preserving the trust and rigor engineers need.

Why teams switch

Finalize projects faster

Cumulus removes the setup and reporting overhead around air dispersion modeling so your team can focus on project decisions and delivery.

Cloud processing No software installs, no dedicated modeling PC
Faster iteration Run, refine, and compare scenarios without long local runtimes
Automated reporting Generate polished, submission-ready EPA reports in a repeatable workflow

No setup burden

Start modeling without installing software, maintaining machines, or coordinating local project files across your team.

Faster iteration

Refine scenarios quickly and keep project momentum moving instead of waiting on long local runtimes and manual handoffs.

Submission-ready output

Produce reporting aligned with common EPA and state submission expectations through a consistent, automated workflow.
