Short summary

Significant efforts are required to estimate the direct radiative effects of aerosols above clouds (DARE_cloudy). We have used a combination of passive and active A-Train satellite sensors and derive mainly positive global and regional DARE_cloudy values (e.g., global seasonal values between 0.13 and 0.26 W m^-2). Despite differences in methods and sensors, the DARE_cloudy values in this study are generally higher than previously reported. We discuss the primary reasons for these higher estimates.
