Hubbard Brook Experimental Forest: 15-Minute Air Temperature Record, 2014 - present

Alternate Identifier:

DOI PLACE HOLDER

Abstract:

Air temperature is measured at 15-minute intervals in six clearings throughout the Hubbard Brook experimental watersheds and at the Headquarters Station. Beginning in 2014, digital sensors housed in aspirated solar radiation shields collected air temperature measurements. These data are gathered at the Hubbard Brook Experimental Forest in Thornton, NH, which is operated and maintained by the USDA Forest Service, Northern Research Station.

Methods and protocols used in the collection of this data package

Description:

Air temperatures from six locations within the HBEF were measured at 15-minute intervals using digital air temperature sensors housed in aspirated solar radiation shields. Five locations are in rain gage openings: 1, 6, 14, 17, and 23. One location is adjacent to the Headquarters building.

Beginning during 2014, Campbell Scientific HMP50/60 or CS215 thermistors were placed in Apogee aspirated shields. Each aspirated shield houses three thermistors and air temperature is reported for each station as the average of the three values, rounded to the nearest half-degree Celsius. Missing values are estimated according to linear regression with the best matched location and are indicated with a flag.

Coordinates of each sampling location are included in the Geographic metadata. They were measured to 1 m accuracy at the precipitation gauge co-located within the same clearing, and thus coordinates are accurate to within ~10 meters of the air temperature sensor.

The elevation of each co-located precipitation station is as follows:

Headquarters: 254.6 m

Station 1: 478.1 m

Station 6: 731.9 m

Station 14: 732.1 m

Station 17: 897.6 m

Station 23: 667.5 m
