A compilation of net primary productivity (NPP) estimates for grasslands has come on-line at the ORNL DAAC. Users will find the compilation handy for comparative study and ecosystem modeling.
"NPP Grassland: NPP Estimates from Biomass Dynamics for 31 Sites, 1948-1994" contains monthly measurements of biomass components and associated environmental data for major grassland types worldwide, as reported in individual ORNL DAAC data sets. Climate data have been added, and results of estimating NPP by means of six separate algorithms are included for locations where sufficient biomass data were available.
