The OML model is an atmospheric dispersion model. The current version is version  6.0 from 2014.

OML is a modern Gaussian plume model intended to be used for distances up to about 20 km from the source. The source is typically one or more stacks, and possibly also area sources. Typically, the OML model is applied for regulatory purposes. In particular, it is the recommended model to be used for environmental impact assessments when new industrial sources are planned in Denmark. The model can be used for both high and low sources; it is not suitable for complex terrain conditions.
