ABSTRACT Systematic measurement of fine particulate matter (aerodynamic diameter less than 2.5 [micro]m [[PM.sub.2.5]]) mass concentrations began nationally with implementation of the Federal Reference Method (FRM) network in 1998 and 1999. In California, additional monitoring of fine particulate matter (PM) occurred via a dichotomous sampler network and several special studies carried out between 1982 and 2002. The authors evaluate the comparability of FRM and non-FRM measurements of [PM.sub.2.5] mass concentrations and establish conversion factors to standardize fine mass measurements from different methods to FRM-equivalent concentrations. The authors also identify measurements of [PM.sub.2.5]] mass concentrations that do not agree with FRM or other independent [PM.sub.2.5] mass...
