Beginning in 2014, solar radiation sensors were implemented at the Hubbard Brook Experimental Forest to measure solar radiation at 15-minute intervals. Two collocated LiCor sensors were installed at Station 1 in July 2014. The 15-minute record for Headquarters begins in 2018 with a single sensor. These data were gathered at the Hubbard Brook Experimental Forest in Woodstock, NH, which is operated and maintained by the USDA Forest Service, Northern Research Station.

Hubbard Brook Experimental Forest: Daily Solar Radiation Measurements, 1959 - present
Daily solar radiation has been measured at Hubbard Brook Experimental Forest Headquarters since 1959, using several different sensors. Radiation was recorded continuously first by a Belfort pyranograph and later by a Weather Measure pyranograph. The pyranograph has been at its current Headquarter location since 1960 and before that at weather station 1, near weir 1. With the installation of the automatic weather station in 1981, a LiCor pyranometer was collocated with the pyranograph and used as the primary radiation sensor. In April, 2018 the LiCor sensor was exchanged for an Apogee SP230 light sensor. Data checking was done on the entire record and values flagged when changes were made to previously posted, erroneous or missing data. These data are gathered at the Hubbard Brook Experimental Forest in Woodstock, NH, which is operated and maintained by the USDA Forest Service, Northern Research Station.

Hubbard Brook Experimental Forest (USDA Forest Service): Vapor Pressure Measurements, 1966 - presentRelative humidity has been measured within the Hubbard Brook Experimental Forest since 1956. Prior to 1981, relative humidity was measured at seven hygrothermographs within the forest, and minimum relative humidity at the time of maximum daily temperature was converted to vapor pressure. Digital data from the hygrothermograph charts are only available for three short periods prior to 1981: January 1966 to April 1966; June 1967 to Sept. 1967 and; May 1971 to April 1973. Beginning in 1981, a humidity sensor has operated as part of the automatic weather station at Headquarters. After installation of the digital sensor in 1981, mean daily air temperature and mean daily relative humidity were converted to vapor pressure. These data were gathered at the Hubbard Brook Experimental Forest in Woodstock, NH, which is operated and maintained by the USDA Forest Service, Northern Research Station.more » « less
