Written only when dispersion is enabled. The first block repeats the basic flow and air variables (as in Atmosphere); the pollutant-specific values follow.
Objects / Flow u, v, w / Wind Speed / Wind Speed Change / Wind Direction
As in the Atmosphere output; the wind field carrying the pollutant.
Pot. Temperature (K)
Air temperature (in Kelvin here).
Spec. Humidity (g/kg) / Relative Humidity (%)
Air humidity.
Vertical / Horizontal Exchange Coef. Impuls (m²/s)
How vigorously the air mixes (and therefore dilutes the pollutant) vertically and horizontally.
For each pollutant you defined, five fields are written (the name in front is your species name, e.g. "NO2"):
… Concentration (µg/m3)
How much of the pollutant is in the air — the headline air-quality number.
… Source (µg/s)
How much is being emitted at that cell.
… Deposition velocity (mm/s)
How fast it settles out of the air onto surfaces.
… Total Deposed Mass (µg/m2)
How much has accumulated on surfaces so far.
… Reaction Term ( )
How much is gained/lost through chemical reactions.
NOx / PM10 combined totals
If you model several species at once, ENVI-met also writes combined NOx and PM10 totals (concentration, source, deposited mass) for convenience.
