Rapid Daytime Estimation of Cloud Properties over a Large Area from Radiance Distributions
Publisher: American Meteorological Society
Abstract: An algorithm is developed to rapidly estimate cloud properties for a large area from daytime imager data. In this context, a large area refers to a grid cell composed of many imager pixels. The algorithm assumes a gamma ...
Implementation of the Daytime Cloud Optical and Microphysical Properties Algorithm (DCOMP) in PATMOS-x
Publisher: American Meteorological Society
Abstract: his paper describes the daytime cloud optical and microphysical properties (DCOMP) retrieval for the Pathfinder Atmosphere?s Extended (PATMOS-x) climate dataset. Within PATMOS-x, DCOMP is applied to observations from the ...
Finite-Cloud Effects in Longwave Radiative Transfer
Publisher: American Meteorological Society
Abstract: As numerical weather and climate prediction models demand more accurate treatment of clouds, the role of finite-cloud effects in longwave radiative transfer clearly warrants further study. In this research, finite-cloud ...
Gazing at Cirrus Clouds for 25 Years through a Split Window. Part I: Methodology
Publisher: American Meteorological Society
Abstract: This paper demonstrates that the split-window approach for estimating cloud properties can improve upon the methods commonly used for generating cloud temperature and emissivity climatologies from satellite imagers. Because ...
Molecular Line Absorption in a Scattering Atmosphere. Part II: Application to Remote Sensing in the O2 A band
Publisher: American Meteorological Society
Abstract: This paper explores the feasibility of using O2 A-band reflectance spectra in the retrieval of cloud optical and physical properties. Analyses demonstrate that these reflection spectra are sensitive to optical properties ...
Global Daytime Distribution of Overlapping Cirrus Cloud from NOAA’s Advanced Very High Resolution Radiometer
Publisher: American Meteorological Society
Abstract: Data from the National Oceanic and Atmospheric Administration?s (NOAA?s) Advanced Very High Resolution Radiometer (AVHRR) instrument are used to provide the mean July and January global daytime distributions of multilayer ...
Molecular Line Absorption in a Scattering Atmosphere. Part III: Pathlength Characteristics and Effects of Spatially Heterogeneous Clouds
Publisher: American Meteorological Society
Abstract: The paper analyzes the influence of horizontal variability of clouds on sunlight reflected in a narrow portion of the solar spectrum and how this influence affects the ability to estimate cloud properties from measurements ...
Daytime Cloud Overlap Detection from AVHRR and VIIRS
Publisher: American Meteorological Society
Abstract: Two algorithms for detecting multilayered cloud systems with satellite data are presented. The first algorithm utilizes data in the 0.65-, 11-, and 12-?m regions of the spectrum that are available on the Advanced Very High ...
The Successive-Order-of-Interaction Radiative Transfer Model. Part I: Model Development
Publisher: American Meteorological Society
Abstract: This study, the first part of a two-part series, develops the method of ?successive orders of interaction? (SOI) for a computationally efficient and accurate solution for radiative transfer in the microwave spectral region. ...
Daytime Global Cloud Typing from AVHRR and VIIRS: Algorithm Description, Validation, and Comparisons
Publisher: American Meteorological Society
Abstract: Three multispectral algorithms for determining the cloud type of previously identified cloudy pixels during the daytime, using satellite imager data, are presented. Two algorithms were developed for use with 0.65-, 1.6-/3.75-, ...
