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 samples
Started: 1994-04-06Weekly collection of precipation for chemical analysis is performed at two different sites. Precipitation amount, pH and conductivity analysis is performed at the sites. The sample is shipped to the NADP Central Analytical Lab in Illinois for analysis of pH, conductivity, Ca, Mg, K, Na, NH4, NO3, Cl, SO4.
Ozone and deposition
Started: 1994-01-01Seasonal continuous ozone (May through September), averaged hourly. Deposition (kg/ha) was calculated for chemicals reporting concentration in mg/l for annual, seasonal and montly time steps.
Meteorological data
Started: 1994-01-01Continuous meteorology averaged hourly includes ambient temperature at 2 and 10 m height, relative humidity, surface wetness, precipitation, wind speed and direction, solar radiation.
Past Methods (No longer in use)
- Sample analysis
Started: 1995-07-04
Ended: 1999-02-02Accumulated weekly samples; analysis includes SO2, HNO3, pH, conductivity, acidity and major ions.
