Marafunga Forest Net Primary Production and Climate Data, 1970-1971

November 1970 through December 1971 data from a lower montane rainforest in Papua New Guinea. This dataset contains net primary production (NPP) component data, including litterfall, LAI, biomass, and nutrient content, alongside climate records of rainfall and temperature. The study was conducted by ORNL_CLOUD across five distinct forest stands.

Use Cases

• Analyzing litterfall rates (755 g/m2/year) as a component of net primary production.
• Correlating daily rainfall records (1969-1971) with forest biomass measurements.
• Studying spatial variation in biomass and nutrient content across Ridge Top, Ridge Gap, Valley, and Slope stands.
• Examining bi-weekly maximum and minimum temperature records at litter level from December 1970 to August 1971.

Strengths

• Provides detailed, site-specific measurements from five distinct forest stands (Ridge Top, Ridge Gap, Valley, Slope, and a harvest stand).
• Includes a multi-year climate record with daily rainfall data from 1969 to 1971.
• Contains field-measured data for above- and below-ground biomass, LAI, litterfall, and nutrient content.

Limitations

• The dataset's exact row count, column names, and file size are unknown across all sources.
• Sources conflict on the last updated date, listing both 1971-12-17 and 2026-03 12.
• Only one component of NPP (litterfall) was fully determined for the site.
