Retrieving of Inhalable Particulate Matter Based on SPOT Image
نویسندگان
چکیده
Abstract: This study built a model with DVI, which is computed by near-infrared and red bands of SPOT-5 image, and observed concentration of PM10 (inhalable particulate matter) to retrieve concentration of PM10 in SPOT-5 image of Beijing urban acquired in 2007. Spatial distribution trends of PM10 are basically identical between retrieved result and observed data. In 2007, inhalable particulate pollution in northern area of Beijing urban is more serious than that in southern area, concentration of PM10 is lower around greenbelt and water body, and it is higher around roads. The retrieval results help us to know the distribution of PM10 pollution, and it is helpful for controlling the air pollution.

متن کاملVehicular particulate matter emissions in road tunnels in Sao Paulo, Brazil.
In the metropolitan area of São Paulo, Brazil, ozone and particulate matter (PM) are the air pollutants that pose the greatest threat to air quality, since the PM and the ozone precursors (nitrogen oxides and volatile organic compounds) are the main source of air pollution from vehicular emissions. Vehicular emissions can be measured inside road tunnels, and those measurements can provide infor...
