The Long-Term Ecological Research Program (LTER) funded by the National Science Foundation’s Division of Biotic Systems, is mandated to pursue ecological research over long time periods at a variety of sites throughout the United States. Climate research is recognized by both ecologists and climatologists as having a key role in long-term ecological research. Each LTER site maintains its own climate program and at many sites climate data represent the longest data set available.
