Getting started
Create a project, add a facility (site), and add emission sources. Few fields are required — official details can be completed later. The source display number is assigned automatically.
Choosing a method
The facility type determines the applicable methodics: the system suggests suitable options, and each methodic’s status is visible in the catalog. A methodic without an "available" status does not offer a calculation.
Guided calculation
Questions are asked one at a time, with units and examples. Table coefficients are selected automatically: you can see the table, the row, and the source. When you change an answer, dependent values refresh and affected results are marked stale.
Maps
Enter the facility and source coordinates to get an overview map and advisory dispersion contours. This is a screening estimate, not a compliance conclusion.
Review and report
The review section shows what is missing: data, materials, stale results. A draft report is available immediately; the final export opens after the findings are resolved.
Term definitions are collected in the glossary.
