Calabozo Savanna Biomass and Climate Data 1969-1987

Four data files detail a 260-hectare humid Trachypogon savanna in Calabozo, Venezuela. Monthly estimates include above-ground biomass for burned and unburned plots from 1969, plus a later period with LAI, nitrogen content, and weather data from 1968-1986. NASA published this dataset, which was checked for accuracy in 1998.

Use Cases

• Comparing above-ground biomass between burned and unburned savanna plots using monthly data from 1969.
• Analyzing the relationship between precipitation, temperature (1968-1986), and estimated net primary productivity (NPP).
• Studying seasonal changes in leaf area index (LAI) and nitrogen content in leaves and stems from 1986-1987.
• Modeling total NPP using harvest-method estimates ranging from 682 to 1,310 g/m2/yr.
• Investigating below-ground biomass dynamics alongside above-ground components.

Strengths

• Data covers a 19-year time range for climate variables (1968-1986) and two distinct study periods for biomass.
• Includes detailed physiological measurements like LAI and nitrogen content for the 1986-1987 period.
• Files were checked for accuracy against the original 1998 publication, ensuring consistency.

Limitations

• Exact row counts and column names are not provided by any source platform.
• Conflicting last_updated dates exist: Data.gov lists 2026-03-12, while NASA Earthdata lists 1987-04 15.
