Location of surface radiation sites

What, where, when… 1-minute data available.

Wanted: Clear Skies!!! SW O FOV LW – “effective” –High, cold cirrus OK

Flux Analysis With LWdn –Continuous estimated clear-sky LWdn –LW cloud effect (clear-measured LW) –LW “effective” sky cover (low and mid) –LW cloud field radiating temperature With SWdn total and diffuse –Identified clear-sky periods –Continuous estimated clear-sky SWdn –SW cloud effect (clear-measured SW) –Total sky cover –For overcast, effective vis optical depth

Flux Analysis With upwelling SW and LW –Continuous estimated clear-sky upwelling SW & LW –Upwelling cloud effect –Complete surface radiative cloud forcing
