Measurements of cloud radiative effect across the Southern Ocean (43 S-79 S, 63 E-158 W)
The surface radiation environment over the Southern Ocean within the region bound by 42.8 S to 78.7 S and 62.6 E to 157.7 W is summarised for three austral summers. This is done using ship-based measurements with the combination of downwelling radiation sensors and a cloud imager. We focus on charac...
