    918918c   Initialization:
    919       scav_ratio_dust = 100 !1 !10 !100 !1000
    920       scav_ratio_wice = scav_ratio_dust
     919      scav_ratio_dust = 20 !1 !10 !100 !1000 ! the scavenging ratio value of 20 is a good compromise to remove the dust in the polar night
     920      scav_ratio_wice = scav_ratio_dust      ! while not drying up the water cycle (which occurs at scav_ratio_wice values above 50 at least)
    921921      pdq_scav(:,:,:)=0.
    922922      pdqsc(:,:)=0.
