 +===== 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.
