Abstract
An updated version of Dong et al. (1998, hereinafter referred to as D98) parameterization is developed from a total of 40 hours of data with a broad range of surface albedos (0.1–0.8) during the 2000–2002 winter seasons at the DOE ARM SGP site. The updated parameterization includes the impact of surface albedo on the retrievals of stratus cloud microphysical and radiative properties, and has a significant improvement over D98 when surface albedo is high. Comparing the retrievals, the cloud‐droplet effective radii (re) calculated from the updated parameterization have a higher correlation coefficient (0.733) and lower Root‐Mean‐Square (RMS) error (1.74 μm or 17.4%) than those (0.602, 4.0 μm or 40%) from the D98. The cloud albedos also have a much higher correlation coefficient (0.983) and lower RMS (3%) than those (0.465, 26%) from the D98. The upper limit of surface albedo is 0.3 in applying the D98.
