Hubbard Brook Experimental Forest: Daily Solar Radiation Measurements, 1959 - ongoing

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.

自1959年起，科研人员便采用多台不同型号传感器，在哈伯德布鲁克实验林场总部（Hubbard Brook Experimental Forest Headquarters）开展每日太阳辐射观测。早期，辐射数据的连续记录采用贝尔福特（Belfort）品牌的日射记录仪（pyranograph），后续更换为Weather Measure品牌的日射记录仪。该日射记录仪自1960年起便安置于当前总部点位，此前则设于紧邻堰1（weir 1）的1号气象站。1981年自动气象站建成投用后，研究人员将LiCor品牌的日射强度计（pyranometer）与该日射记录仪并置安装，并将其作为主要辐射观测传感器。2018年4月，原LiCor传感器被更换为Apogee SP230型光照传感器。研究人员对全部观测记录开展了全量数据校验工作，在对已发布的错误数据或缺失数据进行修正时，均对对应数值予以标记。本次公开的数据集采集自新罕布什尔州伍德斯托克的哈伯德布鲁克实验林场，该林场由美国农业部林务局北部研究站（USDA Forest Service, Northern Research Station）运营维护。
