Groundwater Depth Measurements from a Brazilian Forest Fragment

February 1999 to December 2004 bi-weekly or monthly depth-to-water measurements for three wells in a ~1,500 hectare forest fragment on the Catuaba Experimental Farm, Acre, Brazil. The dataset is provided by NASA and the Federal University of Acre as a single comma-delimited ASCII file. Its primary purpose is to record groundwater level variations over a six-year period in a specific Amazonian forest environment.

Use Cases

• Analyzing seasonal and interannual trends in groundwater depth within a forest fragment using time-series measurements.
• Correlating water table fluctuations with external data on precipitation or tree growth for the Catuaba site.
• Serving as a baseline hydrological record for comparative studies in similar Amazonian forest ecosystems.

Strengths

• Provides a multi-year time series of measurements collected over a 6-year period (1999-2004).
• Focuses on a specific, sizable (~1,500 ha) forest fragment, offering detailed site-level data.

Limitations

• Lacks ground surface elevation reference points, preventing calculation of absolute groundwater table elevation.
• The data provider notes missing or incomplete metadata and documentation, diminishing usability.
• Contains only depth-to-water measurements and is of limited use without paired site data like precipitation.
