NASA's Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) released a new North American Carbon Program (NACP) dataset: PalEON: Terrestrial Ecosystem Model Outputs for the Northeastern U.S., 0850-2010.
This dataset from the Paleo-Ecological Observatory Network (PalEON) Ecosystem Model Intercomparison Project (PEMIP) provides site-specific and regional outputs from terrestrial ecosystem model simulations in the Northeastern U.S. over the time period January 1, 850 (CE), to December 31, 2010. Output variables include key terrestrial ecosystem metrics such as aboveground biomass, autotrophic respiration, evaporation, gross primary productivity, net ecosystem exchange, and net primary productivity. Output variables differ by model.
You can access the data through NASA’s Earthdata Search.
