Short summary

The frequency of occurrence and shortwave direct radiative effects (DRE) of above-cloud aerosols (ACAs) over global oceans are investigated using 8 years of collocated CALIOP and MODIS observations. We estimated that ACAs have a global ocean annual mean diurnally averaged cloudy-sky DRE of 0.015 W m⁻² (range of −0.03 to 0.06 W m⁻²) at TOA. The DREs at surface and within atmosphere are −0.15 W m⁻² (range of −0.09 to −0.21 W m⁻²), and 0.17 W m⁻² (range of 0.11 to 0.24 W m⁻²), respectively.
