Amazon Rainforest Productivity and Climate Data for Manaus, Brazil

Manaus, Brazil is the focus of this dataset containing net primary productivity (NPP) and climate measurements for tropical rainforests. It includes six ASCII files with productivity values for multiple forest types along a hydrologic gradient studied from 1963 to 1990, plus monthly and annual climate data spanning 1910 to 1993. The dataset was compiled by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling carbon budgets using site-specific above-ground NPP estimates ranging from 640 to 800 g/m2/year.
• Analyzing seasonal patterns in tropical forest litterfall using provided seasonality data.
• Comparing biomass stocks across forest types using above- and below-ground biomass data from the 'km64' terra firme site.
• Correlating long-term forest productivity with local climate trends using the 1910-1993 monthly and annual climate records.
• Studying the effect of flooding gradients on ecosystem function using data from terra firme, riverine, and varzea forest sites.

Strengths

• Provides long-term temporal coverage, with climate data spanning 84 years (1910-1993) and NPP measurements over 27 years (1963-1990).
• Includes detailed site characterization across a hydrologic gradient, covering terra firme, riverine, and seasonally inundated (varzea) forests.
• Contains destructive sampling data for one site ('km64'), offering total biomass and vegetation bioelement concentrations.

Limitations

• Key structural details like row count, column names, and exact file sizes are unknown across all platforms.
• There is a conflict in the 'last updated' metadata, with Data.gov reporting 2026-03-12 and NASA Earthdata reporting 1993-12-31.
• The license is specified as 'other-license-specified' on Data.gov but is null on NASA Earthdata, requiring user verification.
