Cumulus - AERMOD Workflow Platform

Build compliance-ready AERMOD projects with less rework.

Map-first inputs, requirement gates, and cloud execution in one controlled workspace.

Cumulus keeps pollutants, sources, receptors, buildings, meteorology, terrain, and downwash aligned so teams can iterate fast, verify readiness, and deliver reproducible regulatory packages.

Use Modeling for rapid iteration and Regulatory for submission-grade execution.

Sources Receptors Buildings Met Data Terrain Regulatory Packaging

Project readiness snapshot

Every run is anchored to a clear project state and a complete input chain.

Pollutant setup and averaging periods

Source, receptor, boundary, and building completeness

Meteorology, terrain, and downwash preprocessing status

Versioned runs with reproducible outputs

Control Panels

Project, Met Data, Terrain, Modeling, and Regulatory in one map workflow.

Execution Modes

Fast technical iteration plus formal regulatory runs with tracked status.

Deliverables

AERMOD inputs, supporting files, and organized output bundles for review.

Operational workflow

A focused sequence that keeps teams aligned from first geometry edit to final package export.

Define project scope

Set project metadata, pollutants, and standards once so every downstream check uses the same assumptions.

Build domain on map

Add boundaries, sources, receptors, and buildings with context-menu actions and immediate visual QA.

Prepare required inputs

Load meteorology and run terrain/downwash preprocessing before launching dispersion workflows.

Run, review, package

Iterate in Modeling, then execute Regulatory to produce compliance-ready and audit-friendly deliverables.

What Cumulus gives your team

Professional controls for data quality, execution consistency, and regulatory confidence.

Structured setup

Project metadata, pollutant settings, and dependencies stay organized and validated from day one.

Precision map editing

Build and refine the modeling domain directly on map layers with immediate visual feedback.

Batch import workflows

Use CSV templates and import modals to scale source and building setup across large projects.

Cloud execution controls

Launch preprocessing and modeling runs with tracked status, reproducible settings, and clear run history.

Review-ready outputs

Generate consistent AERMOD inputs and supporting assets for internal QA and client-facing reporting.

Audit-friendly governance

Maintain a clean record of project changes, model assumptions, and execution outcomes.

Designed for disciplined project teams

Cumulus reduces handoff friction between modelers, reviewers, and compliance stakeholders.

Consistency

Single source of truth for pollutants, geometry, and preprocessing state across collaborators.

Traceability

Every major run is linked to an explicit project snapshot for easier QA and decision logging.

Delivery

Move from scoped setup to submission-grade packages without fragmented tools or manual drift.
