Reflected Fluxes for Broken Clouds over a Lambertian Surface
Publisher: American Meteorological Society
Abstract: Reflected fluxes are calculated for broken cloudiness (i.e., nonplane parallel) as a function of cloud cover, cloud optical depth, solar zenith angle and surface albedo. These calculations extend previous results for broken ...
The Stratocumulus Nature of Fog
Publisher: American Meteorological Society
Abstract: Landsat Multispectral Scanner (MSS) and Thematic Mapper (TM) digital data are used to remotely sense fog properties. These include fog cell size distribution, cell aspect ratio (the ratio of the length of the major and ...
Cumulus Cloud Properties Derived Using Landsat Satellite Data
Publisher: American Meteorological Society
Abstract: Landsat Multispectral Scanner (MSS) digital data are used to remotely sense cumulus cloud properties such as cloud fraction and cloud reflectance, along with the distribution of cloud number and cloud fraction as a function ...
Estimation of Shortwave Direct Radiative Forcing of Biomass-Burning Aerosols Using New Angular Models
Publisher: American Meteorological Society
Abstract: Using a new angular distribution model (ADM) for smoke aerosols, the instantaneous top-of-atmosphere (TOA) shortwave aerosol radiative forcing (SWARF) is calculated for selected days over biomass-burning regions in South ...
Implicit Differencing of Predictive Equations of the Boundary Layer
Publisher: American Meteorological Society
Abstract: The Crank-Nicholson method may not give useful results in detailed prediction of the thermal planetary boundary layer unless tune steps on the order of 10 s are used. In similar problems, lower order time differencing ...
One-Dimensional Numerical Simulation of the Effects of Air Pollution on the Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: A dynamic-numerical model is utilized to study the impact of air pollution on the temperature and wind distributions of the planetary boundary layer. The mathematical model uses a rather complete radiative treatment which ...
Automated Cloud Classification of Global AVHRR Data Using a Fuzzy Logic Approach
Publisher: American Meteorological Society
Abstract: A fuzzy logic classification (FLC) methodology is proposed to achieve the two goals of this paper: 1) to discriminate between clear sky and clouds in a 32 ? 32 pixel array, or sample, of 1.1-km Advanced Very High Resolution ...
Global Survey of the Relationships of Cloud Albedo and Liquid Water Path with Droplet Size Using ISCCP
Publisher: American Meteorological Society
Abstract: The most common approach used to model the aerosol indirect effect on clouds holds the cloud liquid water path constant. In this case, increasing aerosol concentration increases cloud droplet concentration, decreases cloud ...
The 1985 Biomass Burning Season in South America: Satellite Remote Sensing of Fires, Smoke, and Regional Radiative Energy Budgets
Publisher: American Meteorological Society
Abstract: Using satellite imagery, more than five million square kilometers of the forest and cerrado regions over South America are extensively studied to monitor fires and smoke during the 1985 biomass burning season. The results ...
Estimation of Surface and Top-of-Atmosphere Shortwave Irradiance in Biomass-Burning Regions during SCAR-B
Publisher: American Meteorological Society
Abstract: Using in situ measurements of aerosol optical properties and ground-based measurements of aerosol optical thickness (τs) during the Smoke, Clouds and Radiation?Brazil (SCAR-B) experiment, a four-stream broadband radiative ...
