+===== 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.
