Work planned
-use emep birch map (David)
-implement other pollen types
Work done
The Pollen module has been implemented to the emep model.
-The heatsum is now calculated every meteorological timestep (3 hrs).
-The birch fraction has been reduced over 60 degrees north, the same way forest is reduced in land use (lat_fac). However seems that the new numbers are a bit to low, especially at Trondheim av Bodø.
