Retrieval of ice cloud properties using an optimal estimation algorithm and MODIS infrared observations: 1. Forward model, error analysis, and information content
An optimal estimation (OE) retrieval method is developed to infer three ice cloud properties simultaneously: optical thickness (τ), effective radius (r ₑ𝒻𝒻 ), and cloud top height (h). This method is based on a fast ...
Retrieval of ice cloud properties using an optimal estimation algorithm and MODIS infrared observations: 2. Retrieval evaluation
An infrared-based optimal estimation ( OE-IR) algorithm for retrieving ice cloud properties is evaluated. Speciﬁcally, the implementation of the algorithm with MODerate resolution Imaging Spectroradiometer (MODIS) observations ...
A framework for quantifying the impacts of sub-pixel reflectance variance and covariance on cloud optical thickness and effective radius retrievals based on the bispectral method
(American Institute of Physics (AIP), 2017-02-22)
The so-called bi-spectral method retrieves cloud optical thickness (τ) and cloud droplet effective radius (rₑ) simultaneously from a pair of cloud reflectance observations, one in a visible or near infrared (VIS/NIR) band ...
Frequency and causes of failed MODIS cloud property retrievals for liquid phase clouds over global oceans
(American Geophysical Union (AGU), 2015-04-09)
Moderate Resolution Imaging Spectroradiometer (MODIS) retrieves cloud droplet effective radius (rₑ) and optical thickness (τ) by projecting observed cloud reflectances onto a precomputed look‐up table (LUT). When observations ...
Shortwave direct radiative effects of above-cloud aerosols over global oceans derived from 8 years of CALIOP and MODIS observations
(Copernicus Publications on behalf of the European Geosciences Union, 2016-03-04)
In this paper, we studied the frequency of occurrence and shortwave direct radiative effects (DREs) of above-cloud aerosols (ACAs) over global oceans using 8 years (2007–2014) of collocated CALIOP and MODIS observations. ...
