The graphs on this page represent a comparison of the 24 hour particulate concentrations measured with continuous instruments (FDMS) used for near real-time data reporting against daily (24 hour) values measured with Federal Reference Method (FRM) filter based samplers. The real-time data values represent the best estimate of what the FRM values will be based on historic data. FRM sample values are generally available about 1 month after the sampling date.
