flux between snow-free and snow-covered regions, under clear shies, are of the same magni-
tude as differences between overcast and clear-sky conditions over the same surface type. At
around noon, across the southern edge of Vatnajökull on 27 July, and across the northern edge
on 3 August, for example, the net shortwave radiation flux increases from 300 W m 2 over the
