Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Current Methods

  • Particulate matter monitoring
    Started: 1988-09-01

    Particulate matter is being monitored at the PMRC for fine particles <2.5 microns (PM-2.5), using the IMPROVE sampler, is sampled Wednesday & Saturday for mass, and elemental composition (H, Na-Pb).



  • Particulate matter is being monitored at the PMRC for fine particles <2.5 microns (PM-2.5), using the IMPROVE sampler, is sampled every third day for mass, optical absorption and elemental composition (H, Na-Pb).
