NPP Tropical Forest: San Carlos de Rio Negro, Venezuela, 1975-1984, R1

Data Set Overview

Data setNPP Tropical Forest: San Carlos de Rio Negro, Venezuela, 1975-1984, R1
Release date2013-10-17
ProjectNet Primary Productivity (NPP)
Time Period1950-01-01 to 1984-12-31


This data set includes five ASCII files (.txt format). Three files contain above- and below-ground biomass and net primary productivity (NPP) data, one file for each tropical forest study site near San Carlos de Rio Negro, Venezuela. The study sites are located along an ecosystem gradient from riverine to lateritic hill: Tall Amazon Caatinga forest on coarse sandy spodosols close to river level; Bana vegetation on sandy soils less prone to flooding; and Tierra Firme mixed forest on clay oxisols of higher ground. Bioelement concentrations are also provided. The other two files contain climate data from a weather station in San Carlos village.

Net Primary Productivity (NPP): NPP (net primary production) data from existing field measurements are being compiled for approximately 100 study sites covering several major world ecosystem types. These data are used by global change modelers to develop and validate models of vegetation-soil-atmosphere interactions within the global carbon cycle and to help calibrate remote sensing of vegetation worldwide
