FLDS: downwelling longwave flux at surface
A measure of the amount of radiation being radiated downward from the atmosphere. FLDS will be highly positive in the case of black carbon being heated up and re-radiating down back towards the surface. However, FLDS can be positive if the lower atmosphere is warmer than usual.




FLNS: net longwave flux at surface.
A measure of incoming IR - outgoing IR. During the first few winters, incoming IR and outgoing IR just about balance each other out at very high latitudes.
