| Pollutant Data | 62 | Binary (EDX/EDT) |
**PollutantData**
Contains the pollutant data within the model area for every simulation output. Note that the pollutant data is only written if the model area includes sources.
The pollutant data files are produced each main output interval (default: 60 min) and represent the general state and distribution of the pollutants at the given model time.
If Water Spray is used, although modelled through a pollutant source, the outputs for the spray are stored in the [[filereference:output:atmosphere|Atmosphere data (_AT_) file]]
