The National Ecological Observatory Network (NEON) is a continental-scale research platform for discovering and understanding the impacts of climate change, land-use change, and invasive species on ecology. Sponsored by the National Science Foundation (NSF) and managed under cooperative agreement by NEON, Inc., the project was designed to gather long-term data on ecological responses of the biosphere to changes in land use and climate, and on feedbacks with the geosphere, hydrosphere, and atmosphere.
Described below are the research results that served to inform the NEON Domain Development team in creating the 20 NEON domains that are in use today. Based upon a Multivariate Geographic Clustering (MGC) methodology and 1 km2 bio-climatic data, the initial divisions represent objectively defined regions that served as a basis for the NEON domains. This delineation effort, contributed by the authors with input from the NEON Domain Development team, makes NEON one of the first sampling networks to be designed in a scientifically rigorous manner.
These pages chronicle the conceptual development and testing of the statistical domain development methodology.
These pages describe subsequent analyses of representativeness within the 20 NEON domains.
The following slides are from presentations about the NEON domain development effort made at scientific meetings and conferences.
Nine 1 km2 bio-climatic map layers were used to statistically create the ecoregion map from which the NEON domains were developed. A Unix/Linux tar archive file of the nine map layers is available here. Contained in this tar file is a raster mapset for the GRASS geographic information system (GIS). All nine maps are in Lambert Azimuthal Equal Area meters, with −100°E longitude and 45°N latitude center point, no false easting or northing.
The nine map layers are:
Additional metadata for these data layers is available within the data development section of A Flux Atlas for Representativeness and Statistical Extrapolation of the AmeriFlux Network.
