Nocturnal Aerosol Optical Depth Measurements with a Small-Aperture Automated Photometer Using the Moon as a Light Source

Source: Journal of Atmospheric and Oceanic Technology:;2011:;volume( 028 ):;issue: 010:;page 1297

Author(s): Berkoff, Timothy A.; Sorokin, Mikail; Stone, Tom; Eck, Thomas F.; Hoff, Raymond; Welton, Ellsworth; Holben, Brent

Publisher: American Meteorological Society

Abstract: method is described that enables the use of lunar irradiance to obtain nighttime aerosol optical depth (AOD) measurements using a small-aperture photometer. In this approach, the U.S. Geological Survey lunar calibration ...

Estimation of Surface and Top-of-Atmosphere Shortwave Irradiance in Biomass-Burning Regions during SCAR-B

Author(s): Christopher, Sundar A.; Li, Xiang; Welch, Ronald M.; Reid, Jeffrey S.; Hobbs, Peter V.; Eck, Thomas F.; Holben, Brent

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 ...

Optical Properties of Atmospheric Aerosol in Maritime Environments

Source: Journal of the Atmospheric Sciences:;2002:;Volume( 059 ):;issue: 003:;page 501

Author(s): Smirnov, Alexander; Holben, Brent N.; Kaufman, Yoram J.; Dubovik, Oleg; Eck, Thomas F.; Slutsker, Ilya; Pietras, Christophe; Halthore, Rangasayi N.

Publisher: American Meteorological Society

Abstract: Systematic characterization of aerosol over the oceans is needed to understand the aerosol effect on climate and on transport of pollutants between continents. Reported are the results of a comprehensive optical and physical ...

Variability of Absorption and Optical Properties of Key Aerosol Types Observed in Worldwide Locations

Source: Journal of the Atmospheric Sciences:;2002:;Volume( 059 ):;issue: 003:;page 590

Author(s): Dubovik, Oleg; Holben, Brent; Eck, Thomas F.; Smirnov, Alexander; Kaufman, Yoram J.; King, Michael D.; Tanré, Didier; Slutsker, Ilya

Publisher: American Meteorological Society

Abstract: Aerosol radiative forcing is a critical, though variable and uncertain, component of the global climate. Yet climate models rely on sparse information of the aerosol optical properties. In situ measurements, though important ...

Atmospheric Aerosol Optical Properties in the Persian Gulf

Source: Journal of the Atmospheric Sciences:;2002:;Volume( 059 ):;issue: 003:;page 620

Author(s): Smirnov, Alexander; Holben, Brent N.; Dubovik, Oleg; O'Neill, Norm T.; Eck, Thomas F.; Westphal, Douglas L.; Goroch, Andreas K.; Pietras, Christophe; Slutsker, Ilya

Publisher: American Meteorological Society

Abstract: Aerosol optical depth measurements over Bahrain acquired through the ground-based Aerosol Robotic Network (AERONET) are analyzed. Optical depths obtained from ground-based sun/sky radiometers showed a pronounced temporal ...

Nimbus-7 Global Cloud Climatology. Part II: First Year Results

Source: Journal of Climate:;1989:;volume( 002 ):;issue: 007:;page 671

Author(s): Stowe, Larry L.; Yeh, H. Y. Michael; Eck, Thomas F.; Wellemeyer, Charlie G.; Kyle, H. Lee; The Nimbus-7 Cloud Data Processing Team

Publisher: American Meteorological Society

Abstract: Regional and seasonal variations in global cloud cover observed by the Nimbus-7 satellite over 1 year are analyzed by examining the 4 midseason months?April, July and October 1979 and January 1980. The Nimbus-7 data set ...
