2011-04-16: Radiative closure achieved for cloudy skies over Cabauw
The cloudy cases are selected to be overcast, single-layer, homogeneous, nonprecipitating water clouds. The Doubling-Adding KNMI (DAK) code is used to simulate global irradiances. The mean difference between simulated global irradiances and BSRN measurements is 6 W/m2 (5%), with a standard deviation of 14 W/m2 (13%). This difference is within the uncertainties of the model input parameters and measurement errors. The correlation coefficient between the measured and simulated global irradiances is 0.95.
