PM10 Continuous Monitor Comparability Assessments

This tool provides a one-page technical report that assesses the comparability of a PM10 continuous monitor when collocated with an FRM sampler. These reports are intended to assist monitoring agencies in understanding if the PM10 continuous monitors operated in their network are appropriate for their intended monitoring objective (i.e., comparison to the NAAQS and/or reporting the AQI). Data are summarized by season across years, by year, and for all data. The most appropriate way to interpret the comparability of the PM10 continuous monitors is to look at either the entire data set, designated as “AllData” or “A”, or view the last complete year of data. The comparability assessments are presented in the context of several benchmark tests to assist with that evaluation. The assessment methods are described in detail in the following memo - Assessment of PM10 FEMs Compared to Collocated FRMs.
