ARCTIC RADIATION BUDGET CHANGES
interannual and decadal variations for the Arctic region in July. The satellite record of Earth radiation budget demonstrates that the effect of melting ice on the Arctic Ocean has increased the net radiation of the region from 72.5oN to the North Pole from 2 +/-3 W-m-2 to 9 +/-3 W-m-2 during the tw...
