All Norwegian stations 4 day forecast (25 m) based on CAMS (~15km)

Calculations based on the 4 day forecast from EMEP used in CAMS. Includes downscaling of traffic and shipping emissions. Two different methods are shown. The first replaces EMEP local source contribution with independent emission and dispersion calculations made on the subgrid (25m). The second desegregates the EMEP gridded emissions to the subgrid and then applies dispersion calculations. These two methods would give equivalent results if the EMEP grid and uEMEP subgrid emissions were consistent, which they are not.
