RISA Long-Term Record of Aerosol Optical Depth from TOMS Observations and Comparison to AERONET Measurements
Publisher: American Meteorological Society
Abstract: Observations of backscattered near-ultraviolet radiation from the Total Ozone Mapping Spectrometer (TOMS) on board the Nimbus-7 (1979?92) and the Earth Probe (mid-1996 to present) satellites have been used to derive a ...
A Study of Global Aerosol Optical Climatology with Two-Channel AVHRR Remote Sensing
Publisher: American Meteorological Society
Abstract: Global distributions of the aerosol optical thickness and Ångström exponent are estimated from National Oceanic and Atmospheric Administration Advanced Very High Resolution Radiometer channel-1 and -2 radiances for four ...
Nocturnal Aerosol Optical Depth Measurements with a Small-Aperture Automated Photometer Using the Moon as a Light Source
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 ...
Single-Scattering Albedo and Radiative Forcing of Various Aerosol Species with a Global Three-Dimensional Model
Publisher: American Meteorological Society
Abstract: Global distributions of the aerosol optical thickness, Ångström exponent, and single-scattering albedo are simulated using an aerosol transport model coupled with an atmospheric general circulation model. All the main ...
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 ...
Optical Properties of Atmospheric Aerosol in Maritime Environments
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
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 ...

Publisher: American Meteorological Society
Direct Insertion of MODIS Radiances in a Global Aerosol Transport Model
Publisher: American Meteorological Society
Abstract: In this paper results are presented from a simple offline assimilation system that uses radiances from the Moderate Resolution Imaging Spectroradiometer (MODIS) channels that sense atmospheric aerosols over land and ocean. ...
Tropospheric Aerosol Optical Thickness from the GOCART Model and Comparisons with Satellite and Sun Photometer Measurements
Publisher: American Meteorological Society
Abstract: The Georgia Institute of Technology?Goddard Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) model is used to simulate the aerosol optical thickness τ for major types of tropospheric aerosols including ...
