Description
Weekly and monthly measurements from 1999 to 2005 capture dissolved nutrients, organic carbon, and physical water properties from streams in mixed-use and forested landscapes near Paragominas, Para, Brazil. A separate 2004 dataset provides complementary forest productivity metrics, including leaf area index, dendrometry, and litterfall mass from primary tropical forest plots in the Tapajós National Forest. The combined data supports analysis of land-use impacts on aquatic and terrestrial ecosystem processes in the Amazon.
Use Cases
Analyzing the relationship between land use (forest vs. mixed agriculture) and stream water nutrient concentrations.
Modeling forest carbon dynamics using concurrent measurements of litterfall mass and dendrometry.
Assessing seasonal and interannual variability in stream discharge, pH, and dissolved oxygen in Amazonian watersheds.
Calibrating remote sensing estimates of forest productivity with ground-based leaf area index (LAI) measurements.
Strengths
Multi-year temporal coverage from 1999 to 2005 for stream chemistry, providing a multi-year baseline.
Includes complementary terrestrial forest metrics (LAI, litterfall) from a primary forest site for 2004.
Data collected by NASA, indicating a standardized measurement protocol and institutional oversight.
Limitations
Metadata completeness is low: column names, row counts, and specific file structures are not provided.
The temporal and spatial coverage between the stream chemistry (1999-2005, Paragominas) and forest metrics (2004, Tapajós) datasets is not fully aligned.
