Cloud Inhomogeneity from MODIS
Publisher: American Meteorological Society
Abstract: Two full months (July 2003 and January 2004) of Moderate Resolution Imaging Spectroradiometer (MODIS) Atmosphere Level-3 data from the Terra and Aqua satellites are analyzed in order to characterize the horizontal variability ...
Predictability in a Solvable Stochastic Climate Model
Publisher: American Meteorological Society
Abstract: We Present a simple Budyko-Sellers type climate model which is forced by a heating term whose time dependence is white noise and whose space-separated autocorrelation is independent of position and orientation on the sphere ...
Interannual Variability and Climatic Noise in Satellite-Observed Outgoing Longwave Radiation
Publisher: American Meteorological Society
Abstract: The interannual variability (IAV) in monthly averaged outgoing infrared radiation (IR, from the NOAA polar orbiting satellites) is observed to be larger during summer than during winter over the north Pacific Ocean. A ...
Fractal Statistics of Cloud Fields
Publisher: American Meteorological Society
Abstract: Landsat Multispectral Scanner (MSS) and Thematic Mapper (TM) data, with 80 and 30 m spatial resolution, respectively, have been employed to study the spatial structure of boundary-layer and intertropical convergence zone ...
A Stability Theorem for Energy-Balance Climate Models
Publisher: American Meteorological Society
Abstract: This paper treats the stability of steady-state solutions of some simple, latitude-dependent, energy-balance climate models. For north-south symmetric solutions of models with an ice-cap-type albedo feed-back, and for the ...
The Plane-Parallel Albedo Bias of Liquid Clouds from MODIS Observations
Publisher: American Meteorological Society
Abstract: The authors present the global plane-parallel shortwave albedo bias of liquid clouds for two months, July 2003 and January 2004. The cloud optical properties necessary to perform the bias calculations come from the operational ...
Nearest Neighbor Spacing of Fair Weather Cumulus Clouds
Publisher: American Meteorological Society
Abstract: Histograms of nearest neighbor spacings of fair weather cumulus at 15 locations Over the world's oceans are presented based on the analysis of high resolution LANDSAT 3 Multispectral Scanner images for amounts of cloud ...
Liquid Water Path and Plane-Parallel Albedo Bias during ASTEX
Publisher: American Meteorological Society
Abstract: Inhomogeneous distributions of liquid water like those observed in real clouds generally reflect less solar radiation than idealized uniform distributions assumed in plane-parallel theory. Here the authors determine cloud ...
Windowed and Wavelet Analysis of Marine Stratocumulus Cloud Inhomogeneity
Publisher: American Meteorological Society
Abstract: To improve radiative transfer calculations for inhomogeneous clouds, a consistent means of modeling inhomogeneity is needed. One current method of modeling cloud inhomogeneity is through the use of fractal parameters. This ...
A New Normalized Difference Cloud Retrieval Technique Applied to Landsat Radiances over the Oklahoma ARM Site
Publisher: American Meteorological Society
Abstract: The authors propose a new cloud property retrieval technique that accounts for cloud side illumination and shadowing effects present at high solar zenith angles. The technique uses the normalized difference of nadir ...
