NPP Tropical Forest: Luquillo, Puerto Rico, 1946-1994, R1

Data Set Overview

Data setNPP Tropical Forest: Luquillo, Puerto Rico, 1946-1994, R1
Release date2013-10-17
ProjectNet Primary Productivity (NPP)
Time Period1946-01-01 to 1994-12-31


This data set contains ten ASCII files (.txt format), one NPP file for each of the nine different montane tropical rainforest sites within the Luquillo Experimental Forest (LEF) of Puerto Rico and one file containing climate data. The NPP study sites are located along an environmental gradient of different soils, elevation (100-1,000 m), develop stage, and mean annual rainfall. Field measurements were carried out from 1946 through 1994.

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
