Andrews Experimental Forest in the USA hosts one of the nation's least contaminated long-term precipitation chemistry records. The dataset contains chemical analyses from rain collector samples, initiated in 1969 by SCIOPS to evaluate nutrient inputs and outputs from forest systems. It supports general monitoring and is conducted alongside streamflow chemistry and the National Atmospheric Deposition Program.
Use Cases
- Analyze trends in nutrient concentrations (e.g., nitrogen, phosphorus) over the 50+ year time-series to assess environmental change.
- Model dry deposition chemistry by correlating precipitation chemistry data with atmospheric conditions and forest canopy interactions.
- Calculate nutrient budgets for small watersheds by integrating precipitation chemistry with streamflow chemistry data.
- Compare contamination levels of precipitation chemistry at this site with other national monitoring networks like NADP.
Strengths
- Time-series data initiated in 1969, providing over 50 years of continuous monitoring.
- Described as among the least contaminated precipitation chemistry records within the USA.
Limitations
- Specific sample size, row count, and measured chemical columns are unknown.
- Geographic scope is limited to the Andrews Experimental Forest, which may not represent broader regions.
