ChEAS Data

The Chequamegon Ecosystem-Atmosphere Study (ChEAS ) is a research cooperative that seeks to understand carbon and water cycles of terrestrial ecosystems at regional scales, using the Northwoods of Wisconsin as our study region. This page provides links to existing repositories and metadata of ChEAS flux tower sites. Please let me know of dead links.

All data are publicly accessible and open for use in research, but I request (but do not require) that you contact me prior to presentation or publication and acknowledge funding and site publication. Please acknowledge funding and cite the primary citation for each tower site you use. Please also be sure to be familiar with the Ameriflux fair-use policy
