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 Hydrocarbon database contains
approximately 29,000 hourly measurements for twenty different
hydrocarbon species (ethane, ethene, ... etc.) from 1992 through
1995. 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.

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