A new, more accurate formula for calculating the net longwave radiation flux LW ?? has been devised for the Baltic Sea region. To this end, the following sets of simultaneously measured data regarding the longwave radiation of the sea and the atmosphere were used: the temperatures of the sea surface and its contiguous air layer, the water vapour pressure in the air above the water, and the cloud cover. These data were gathered during numerous research cruises in the Baltic in 2000-03 and were supplemented by satellite data from Karlsson (2001) characterising the cloud cover over the whole Baltic. The formula established for LW ?? can be written in the form of three alternative equations, differing with respect to their cloud cover functions: [formula]
