Methods

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

Current Methods

  • Precipitation sampling
    Started: 1993-01-01

    Year-round daily wet-only precipitation sampling includes: amount, field pH and conductivity, lab pH and conductivity, Ca, K, Mg, Na, NO3, Cl, SO4 and PO4.

    Quality Control Measures: Periodic site maintenance and bi-annual calibration, annual site certification, documented QA/QC protocol for field procedures and lab analyses.
