This study reviewed the prediction of fine particulate matter () from satellite aerosol optical depth (AOD) and summarized the advantages and limitations of these predicting models. A total of 116 articles were included from 1436 records retrieved. The number of such studies has been increasing since 2003. Among these studies, four predicting models were widely used: Multiple Linear ...

Methodology to Calculate Particulate Matter (PM) 2

components from material in the earth’s crust, such as dust, are also present, with the amount varying in different locations. Staff’s recommendation for calculating focuses only on directly emitted In 1997, EPA established an annual and a 24hour standard for the finest fraction of particulates, , to complement the existing PM10 standards. However, EPA ...

refers to atmospheric particulate matter (PM) that have a diameter of less than micrometers, which is about 3% the diameter of a human hair. Commonly written as PM , particles in this category are so small that they can only be seen with a microscope. They are even smaller than their counterparts PM 10, which are particles that are 10 micrometres or less, and are also called fine ...
