Pasture Soil Water and Precipitation Data from Manaus, Brazil (1999-2001)

1999-2001 soil water measurements to a 3-meter depth and monthly precipitation data from a pasture research site near Manaus, Brazil. The dataset consists of three CSV files and was collected as part of the LBA-ECO project. Data quality is flagged as having issues, including missing documentation and unspecified units.

Use Cases

• Analyzing seasonal and interannual variability in soil moisture at different depths (up to 3 meters).
• Correlating monthly precipitation totals with subsurface soil water content changes.
• Providing ground reference data for satellite-based soil moisture or precipitation product validation in a pasture environment.
• Studying the water balance and hydrologic processes in a managed tropical pasture ecosystem.

Strengths

• Provides multi-year, in-situ measurements for a specific land cover type (pasture) from 1999 to 2001.
• Contains depth-resolved soil water data, offering a profile rather than a single surface measurement.
• Cross-platform presence on NASA EarthData and Data.gov indicates recognized scientific importance.

Limitations

• Explicit data quality statement notes missing/incomplete data, metadata, and documentation.
• Column names and row counts are unknown, limiting precise analysis.
• Conflicting 'last updated' dates (2001-12-31 and 2026-03-13) create uncertainty about metadata maintenance.
