Concentration, Ambient†
Based in part on the article “Ambient concentrations” by Philip K Hopke, which appeared in the Encyclopedia of Environmetrics.
Abstract
Data analysis of ambient atmospheric data focuses on the variations in values from the “typical” or average values of the measured variables. To provide a baseline for such studies, the concentrations of the major gaseous constituents of the atmosphere are summarized along with the physical and chemical characteristics of ambient particulate matter.
