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 ...
Comparisons of bispectral and polarimetric retrievals of marine boundary layer cloud microphysics: case studies using a LES–satellite retrieval simulator
(Copernicus Publications, 2018-06-26)
Many passive remote-sensing techniques have been developed to retrieve cloud microphysical properties from satellite-based sensors, with the most common approaches being the bispectral and polarimetric techniques. These ...
The impact of cloud vertical profile on liquid water path retrieval based on the bispectral method: A theoretical study based on large‐eddy simulations of shallow marine boundary layer clouds
Passive optical retrievals of cloud liquid water path (LWP), like those implemented for Moderate Resolution Imaging Spectroradiometer (MODIS), rely on cloud vertical profile assumptions to relate optical thickness (τ) and ...
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. ...
