Conditions for deriving air quality information from satellite data

Stirnberg, Roland; Cermak, Jan

Abstract:
This contribution presents an approach to map urban air quality using passive-sensor satellite data.
Air pollution is inherently a spatial phenomenon: airborne transport of substances yields a multi-source mixture
of pollutants at any given location, at and beyond source regions like cities. Thus, satellite data may provide infor-
mation on the distribution of pollutants relative to geophysical parameters pertaining to surface and atmospheric
states. We develop a method to estimate spatial patterns of street-level particulate matter (PM) concentrations
based on satellite-retrieved aerosol optical depth (AOD). AOD data is obtained based on the Multi-Angle
Implementation of Atmospheric Correction (MAIAC) algorithm applied on data from the Moderate Resolution
Imaging Spectroradiometer (MODIS) instrument.
The relationship between vertically integrated AOD and PM at street level is modulated by variability in
geophysical conditions. Hence, we focus on the detection of sets of conditions that allow a reliable analysis of
street-level air pollution based on satellite-derived AOD. AOD and ... mehr
