SAMPLING DESIGN
Air temperature is currently measured at 8 locations. Six locations are in rain gage openings 1, 6, 14, 17, 23, and 24. One location is Headquarters. The INT station is below the forest canopy (not in an opening) at the integrated plot area, west of weir 4. At each station, air temperature (and usually relative humidity) are recorded by Belfort hygrothermographs housed in standard Stevenson screens, 5 feet off the ground. Each screen also houses a maximum, a minimum, and a standard thermometer. The hygrothermograph charts are changed weekly, at which time the thermometers are read. Daily maximum and minimum temperatures are read manually from the charts. Correction for disagreement with the thermometers are seldom made as agreement is usually within 2 degrees F. The hygrothermographs are readjusted annually to give the daily mean. The daily maximum and minimum temperatures are entered directly into the computer. Maximum and minimum temperatures are converted from Fahrenheit to Celsius and then averaged to give the daily mean.
DATA DESCRIPTION
Daily mean temperatures from up to 8 locations at HBEF have been measured since October, 1955 using mechanical hygrothermographs in weather shelters.
DATA ACCESS GUIDELINES
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.
The access to all LTER data is subject to requirements set forth by this policy document to enable data providers to track usage, evaluate its impact in the community, and confirm users' acceptance of the terms of acceptable use. These requirements are standardized across the LTER Network to provide contractual exchange of data between Site Data Providers, Network Data Providers, and Data Users that can be encoded into electronic form and exchanged between computers. This will allow direct access to data via a common portal once these requirements have been fulfilled. The following information may be required directly or by proxy prior to the transference of any data object:

The Data User will provide the data contact with two reprints of any publications resulting from use of the Data Set and will provide copies, or on-line access to, any derived digital products. Notification will include an explanation of how the Data Set was used to produce the derived work.
Collaboration. The Data Set has been released in the spirit of open scientific collaboration. Data Users are thus strongly encouraged to consider consultation, collaboration and/or co-authorship with the Data Set Creator.
By accepting this Data Set, the Data User agrees to abide by the terms of this agreement. The Data Owner shall have the right to terminate this agreement immediately by written notice upon the Data User's breach of, or non-compliance with, any of its terms. The Data User may be held responsible for any misuse that is caused or encouraged by the Data User's failure to abide by the terms of this agreement.

NOTES ON DATA
Comparisons among stations should be made with caution because data have not been corrected for possible instrument bias. -99.0 is the missing value when the weather station is not operating. 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.
