The output properties are extinction, scattering, and absorption coefficients; single-scattering albedo; asymmetry parameter; and aerosol optical depth
(in the atmospheric mode).
2010) integrated the satellite-based aerosol optical depth
(AOD) and the chemical transport models (CTM) to develop concentrations of particulate matter < 2.
ISCCP also provides two-dimensional histograms of cloud optical depth
and pressure, which are based on pixel-level results.
We agree that integration of satellite-based aerosol optical depth
(AOD) with a chemical transport model (CTM) is valuable to develop estimates of air quality.
Currently passive sensors provide information on aerosol optical depth
and aerosol typing but vertical height information is difficult to derive using passive technology.
5] concentrations using total-column aerosol optical depth
(AOD) from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Multiangle Imaging Spectroradiometer (MISR) satellite instruments and coincident aerosol vertical profiles from the GEOS-Chem global chemical transport model.
The main task will be the development of a climatology of stratospheric aerosol extinction and optical depth
from the GOMOS instrument and the implementation of stratospheric corrections for tropospheric measurements.
The satellite data yield a measurement called aerosol optical depth
(AOD), which relates to the total amount of aerosol particles in the air between the ground and the satellite.

The association between satellite-based aerosol optical depth
We hope this exchange will highlight some of the key issues in using aerosol optical depth
(AOD) for air quality purposes, in particular with regard to our focus on epidemiologic use.
Assuming similar optical properties of biomass smoke in Southeast Asia and Brazil, where UV-B and optical depth
are highly correlated, optical depth
measurements over Thailand and Vietnam by NASA's Terra and Aqua satellites suggest highly suppressed UVB during these avian influenza outbreaks (Mims FM III, unpublished data).
