An evaluation of Terra-MODIS sampling for monthly and annual particulate matter air quality assessment over the Southeastern United States
Although satellites provide reliable and repeated measurements on a global basis, particulate matter air quality information can be derived from satellites only when clouds are absent and when surface conditions are favorable. However, ground measurements provide particulate matter information irrespective of cloud cover and surface conditions. Therefore there could be a sampling bias when usin...
متن کاملSeven year particulate matter air quality assessment from surface and satellite measurements
Using seven years of the Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol optical thickness (AOT) data and ground measurements of particulate matter mass over one site in the Southeastern United States (33.55 N, 86.82 W) we present a comprehensive analysis of various aspects of particulate matter air quality. Monthly, seasonal and inter-annual relationships are examined with emphas...
متن کاملParticulate matter air quality assessment using integrated surface, satellite, and meteorological products: Multiple regression approach
[1] Monitoring particulate matter air quality from spaceborne measurements is largely confined to relating columnar satellite retrievals of aerosol optical thickness (AOT) with ground measurements of PM2.5 mass concentration. However, vertical distribution of aerosols and meteorological effects such as wind speed, temperature, and humidity also play a major role in this AOT-PM2.5 relationship. ...
متن کاملEstimating fine particulate matter component concentrations and size distributions using satellite-retrieved fractional aerosol optical depth: part 2--a case study.
We use the fractional aerosol optical depth (AOD) values derived from Multiangle Imaging Spectroradiometer (MISR) aerosol component measurements, along with aerosol transport model constraints, to estimate ground-level concentrations of fine particulate matter (PM2.5) mass and its major constituents in the continental United States. Regression models using fractional AODs predict PM2.5 mass and...
متن کاملSatellite remote sensing of particulate matter air quality: the cloud-cover problem.
Satellite assessments of particulate matter (PM) air quality that use solar reflectance methods are dependent on availability of clear sky; in other words, mass concentrations of PM less than 2.5 microm in aerodynamic diameter (PM2.5) cannot be estimated from satellite observations under cloudy conditions or bright surfaces such as snow/ice. Whereas most ground monitors measure PM2.5 concentrat...
