Estimating ground-level PM10 using satellite remote sensing and ground-based meteorological measurements over Tehran

BACKGROUND AND METHODOLOGY Measurements by satellite remote sensing were combined with ground-based meteorological measurements to estimate ground-level PM10. Aerosol optical depth (AOD) by both MODIS and MISR were utilized to develop several statistical models including linear and non-linear multi-regression models. These models were examined for estimating PM10 measured at the air quality sta...

Estimating ground-level PM2.5 in the eastern United States using satellite remote sensing.

An empirical model based on the regression between daily PM2.5 (particles with aerodynamic diameters of less than 2.5 microm) concentrations and aerosol optical thickness (AOT) measurements from the multiangle imaging spectroradiometer (MISR) was developed and tested using data from the eastern United States during the period of 2001. Overall, the empirical model explained 48% of the variabilit...

Estimating ground-level PM2.5 using aerosol optical depth determined from satellite remote sensing

[1] We assess the relationship of ground-level fine particulate matter (PM2.5) concentrations for 2000–2001 measured as part of the Canadian National Air Pollution Surveillance (NAPS) network and the U.S. Air Quality System (AQS), versus remotesensed PM2.5 determined from aerosol optical depths (AOD) measured by the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Multiangle Imagin...

A semi-empirical model for predicting hourly ground-level fine particulate matter (PM2.5) concentration in southern Ontario from satellite remote sensing and ground-based meteorological measurements

Mesoscale distributions of UV spectral irradiance obtained by merging satellite remote sensing and ground-based measurements

Global atmospheric trends in ozone column amount has focused attention on the environmental risk of exposure to ultraviolet (UV) radiation. Monitoring UV irradiance in diverse and remote locations is necessary to understand the variability of exposure, dose rates and resultant vulnerability of ecological systems. The USDA UV-B Monitoring Program maintains a wide network for ground-based continu...
