EPA AERMOD · cloud-native

Air-dispersion modeling, minus the infrastructure.

Breeze runs EPA AERMOD on elastic Azure compute. Upload your input package, submit a run, and download regulatory-grade results — no local install, no cluster to babysit.

  • EPA-published AERMOD
  • Runs on Azure Batch
  • Reproducible run manifests

Everything a modeling run needs

A focused workflow around the parts that actually matter — inputs, compute, status, and defensible outputs.

No install, no infrastructure

Skip the local AERMOD setup and cloud plumbing. Sign in from a browser and start modeling immediately.

Elastic compute

From single-core to 128-core parallel (MPI) for large receptor grids. Choose the tier per run; nodes scale from zero.

Live run tracking

Business-level statuses — queued, running, postprocessing — with queue position estimates and live timing.

Regulatory-grade & reproducible

Every run pins the AERMOD version and records an input hash and run manifest for regulatory defensibility.

Team workspaces

Organization → group → user. Switch your active workspace; projects, isolation, and billing live per group.

Secure by design

Per-tenant isolation, short-lived signed URLs for every file transfer, and audited administrative actions.

How it works

From input package to results in four steps

01

Upload inputs

Add your AERMOD input package to a project. Files are stored per workspace.

02

Submit a run

Pick an input file and a compute tier, then submit. Idempotent — safe to retry.

03

Track progress

Watch the run move through the queue and compute with live status and timing.

04

Download results

Grab individual outputs and logs, or the full results bundle as a single zip.

Compute

Scale cores to the job

Single-core is the default and covers most runs. Parallel tiers run AERMOD via MPI and pay off on large receptor grids — enabled per contract.
