The discovery of the thinning of the Antarctic ozone layer every austral spring led to intense discussions at the international level and culminated in the historic agreement of September 1987: the Montreal Protocol on Substances that Deplete the Ozone...
A selective, commercial harvest adjacent to Harvard Forest provides a unique opportunity to monitor changes in the distribution and amount of Carbon sequestration in a managed forest. The suite of ecological measurements used in the tower footprint was...
In North America, anthropogenic activities such as fossil fuel combustion and high-intensity agriculture have increased the inputs of nitrogen oxides in the atmosphere far above natural, biogenic inputs. The effect of this excess N depends on how it is...
Our tower-based CO 2 measurements examine how regional and ecosystem level processes in a mid-latitude forest contribute to global carbon cycling. Specifically, we endeavor to understand quantitatively how and why forested ecosystems take up or release...
The automated Environmental Monitoring Station (EMS) monitors the concentration of a variety of chemical species, in addition to general environmental measurements. These species include NOy, NOx, CO 2, H 2O, O 3, CO, and several different hydrocarbons...
Harvard Forest is comprised of approximately 3000 acres of land in Petersham, Massachusetts that include mixed hardwood and conifer forests, ponds, extensive spruce and maple swamps, and diverse plantations. The Harvard Forest Environmental Measurement...
