RAP 16-Day Production
Rangeland Analysis Platform (RAP)
Datasets:
- RAP 16-day Herbaceous Production
Description:
- RAP Herbaceous Production, version 3.0: This dataset consists of gridded estimates of herbaceous aboveground biomass, partitioned into vegetation types for annual forbs and grasses and perennial forbs and grasses. The estimates are produced at 30m spatial resolution from 1986-present and are provided annually (available through Climate Engine, as described here) and at 16-day intervals. Values are provided, initially, in terms of net primary productivity which are converted to pounds per acre of new growth of aboveground biomass. Estimates are calculated using a light-use efficiency model (to estimate net primary production in terms of carbon) which is then allocated to aboveground and belowground pools (based on mean annual temperature) and further converted to biomass using a carbon-to-dry matter ratio.
Organization: Maintained and produced by USDA Agricultural Research Service; initially developed by the University of Montana, Numerical Terradynamic Simulation Group
