Moisture Fluxes Derived from EOS Aqua Satellite Data for the North Water Polynya Over 2003-2009
Satellite data were applied to calculate the moisture flux from the North Water polynya during a series of events spanning 2003-2009. The fluxes were calculated using bulk aerodynamic formulas with the stability effects according to the Monin-Obukhov similarity theory. Input parameters were taken fr...

Satellite data were applied to calculate the moisture flux from the North Water polynya during a series of events spanning 2003-2009.
