Publications using these data from the Hubbard Brook Ecosystem Study must include the following paragraph: Some data used in this publication were obtained by scientists of the Hubbard Brook Ecosystem Study; this publication has not been reviewed by those scientists. The Hubbard Brook Experimental Forest is operated and maintained by the Northeastern Research Station, U.S. Department of Agriculture, Newtown Square, Pennsylvania. Please note that data sharing and availability policy varies among the datasets available. Publishers of Hubbard Brook data are encouraged to contact the original data provider to obtain information for an acknowledgement of the original funding source of the research.

Daily maximum and minimum temperatures from up to 8 locations at HBEF have been measured since October, 1955 using mechanical hygrothermographs in weather shelters.

Comparisons among stations should be made with caution because data have not been corrected for possible instrument bias. -99 is the missing value for the times when the weather station is not operational. Otherwise, if a day is missed, the value for that day has been estimated from values at the other stations. Estimated values are not flagged. The Fahrenheit to Celcius conversion and rounding to whole degrees Centigrade leads to considerable underrepresentation of -5, 0, 5, 10, etc. values. The data is physically located at the USDA Forest Service, Durham, NH and was last updated on March 11, 2003.
