Summary

The Harvard Forest environmental measurement site is part of the
AmeriFlux network of field research projects quantifying the exchange
of carbon dioxide between terrestrial ecosystems and the
atmosphere. The Harvard Forest AmeriFlux database contains
approximately 53,000 hourly CO2, water vapor, and energy exchange
... measurements using the eddy covariance technique from 1991-1996. CDIAC
re-processed the data the data to conform to naming conventions and
data reporting standards agreed to be the AmeriFlux Science Team. The
files contain timestamps relative to January 1990 to facilitate future
integration and synthesis of data across the entire AmeriFlux network.

CO2 Flux data from the Harvard Forest Ameriflux site is available directly
from CDIAC at:
