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 and volume
Started: 1980-01-01Precipitation volume and pH are recorded on an event basis.
Rain and snow collection
Rainfall is intercepted by a funnel and passes through a length of tygon tubing until it reaches and is collected in a one gallon jug. Snow is collected and melted indoors to completely melt before pH is measured.
