Using operational HMS smoke observations to gain insights on North American smoke transport and implications for air quality
MetadataShow full item record
Wildfires represent a major challenge for air quality managers, as they are large sources of particulate matter (PM) and ozone (O3) precursors, and they are highly dynamic and transient events. Smoke can be transported thousands of kilometers to deteriorate air quality over large regions. Under a warming climate, fire severity and frequency are likely to in- crease, exacerbating an existing problem. Using the National Environmental Satellite, Data and Information Service (NESDIS) Hazard Mapping System (HMS) smoke data for the U.S. and Canada for the period 2007 to 2014, I examine a subset of ...
