Data Sets
The Harvard Forest (near Petersham, Worcester County, Massachusetts) and Duke Forest (near Hillsborough, Orange County, North Carolina) warming experiment sites share the same experiment design and instrumentation. At each site, soil and air heating is carried out in eighteen open-topped chambers and 6 non-chamber controls. Experimental treatments include three levels of heating (ambient/control, +3° C, and +5° C) and low-light (understory) versus high-light (artificially created gap) conditions. Each of these chambers contains sensors to measure air temperature, soil temperature, relative humidity, soil moisture, and photosynthetically active radiation. These environmental data, recorded on an hourly basis by Campbell Scientific CR1000 data loggers, are available below.
