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 ...
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. ...
An Assessment of the Impacts of Cloud Vertical Heterogeneity on Global Ice Cloud Data Records From Passive Satellite Retrievals
(AGU Pubication, 2019-02-02)
Spaceborne passive instruments are widely used to infer long‐term ice cloud properties due to their large temporal and spatial coverage. Although observations from active instruments demonstrate ice particle variability ...
