EPA's Utilization of Portable Emission Measurement Systems (PEMS)
Gene Tierney
EPA Office of Transportation and Air Quality
Portable emission measurement systems (PEMS) are becoming increasingly capable of providing very high quality emission and activity information on motor vehicles and engines. EPA has been purchasing and deploying these devices to gather emission factor and activity information in various test programs. Available technology will be discussed. Data from EPA test programs will be reviewed in comparison with existing sources of information. Plans for future deployment will be addressed.
