Retrieving vertical profiles of water-cloud droplet effective radius: Algorithm modification and preliminary application
[1] Chang and Li [2002] proposed a new cloud microphysics retrieval technique that can estimate the vertical profile of droplet effective radius (DER) for water clouds using multispectral near-infrared (NIR) measurements. The underlying principle of the retrieval technique is that radiance measurements at distinct multi-NIR wavelengths possess different penetration depths inside the cloud and t...
متن کاملEstimating the vertical variation of cloud droplet effective radius using multispectral near-infrared satellite measurements
[1] This paper presents a satellite-based retrieval method for inferring the vertical variation of cloud droplet effective radius (DER) by utilizing multispectral near-infrared (NIR) measurements at 1.25, 1.65, 2.15, and 3.75 mm, available from the Moderate Resolution Imaging Spectrometer (MODIS) satellite observations. The method is based on the principle that these multispectral NIR measureme...
متن کاملParameterization of Cloud Droplet Effective Radius: Effects of Spectral Dispersion and Skewness of Cloud Droplet Size Distributions
Effective radius re (defined as the ratio of the third to the second moment of a droplet size distribution) is one of the crucial variables that determine the radiative properties of liquid water clouds (Hansen and Travis 1974). The inclusion and parameterization of re in climate models has proven to be critical for assessing global climate change (Slingo 1990; Dandin et al. 1997). There has be...
متن کاملStudying the vertical variation of cloud droplet effective radius using ship and space-borne remote sensing data
[1] The albedo of marine stratocumuli depends upon cloud liquid water content, droplet effective radius (re), and how these parameters vary with height. Using satellite data and shipborne data from the East Pacific Investigation of Climate (EPIC) Stratocumulus Study, this study investigates the cloud re vertical variation for drizzling and nondrizzling clouds. Visible/near-infrared retrievals f...
