► Methods
- Current Methods
- Precipitation and volume
- Started: 1980-01-01
- Method Description: Precipitation volume and pH are recorded on an event basis.
- Started: 1980-01-01
- Rain and snow collection
- Method Description: 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.
► Sampling Equipment
- Current Equipment
- Bucket
- Started: 1980-01-01
- Sampling Description: Snow is collected in a five gallon polyethylene bucket.
- Digital pH meter, combination electrode
- Started: 1980-01-01
- Sampling Description: Cole Parmer digital pH meter model 5987, and a Cole Parmer combination electrode with a calomel reference
- Rainfall collector
- Started: 1980-01-01
- Sampling Description: Rainfall collector is a screened funnel with a one gallon polyetheylene collection jug.
► Site Characteristics
- Site Description: Field stations at Proctor Maple Research Center (400 m) and Mt. Mansfield summit at the WCAX transmitter station (1204 m).
- Site Description: Mount Mansfield Summit site is located at 44.5250087 N, 72.8148911 W (NAD83 format) at an elevation of 3938 ft.
