NREL Solar Radiation Research Laboratory (SRRL): Baseline Measurement System (BMS); Golden, Colorado (Data)

The SRRL was established at the Solar Energy Research Institute (now NREL) in 1981 to provide continuous measurements of the solar resources, outdoor calibrations of pyranometers and pyrheliometers, and to characterize commercially available instrumentation. The SRRL is an outdoor laboratory located on South Table Mountain, a mesa providing excellent solar access throughout the year, overlooking Denver. Beginning with the basic measurements of global horizontal irradiance, direct normal irradiance and diffuse horizontal irradiance at 5-minute intervals, the SRRL Baseline Measurement System now produces more than 130 data elements at 1-min intervals that are available from the Measurement & Instrumentation Data Center Web site. Data sources include global horizontal, direct normal, diffuse horizontal (from shadowband and tracking disk), global on tilted surfaces, reflected solar irradiance, ultraviolet, infrared (upwelling and downwelling), photometric and spectral radiometers, sky imagery, and surface meteorological conditions (temperature, relative humidity, barometric pressure, precipitation, snow cover, wind speed and direction at multiple levels). Data quality control and assessment include daily instrument maintenance (M-F) with automated data quality control based on real-time examinations of redundant instrumentation and internal consistency checks using NREL's SERI-QC methodology. Operators are notified of equipment problems by automatic e-mail messages generated by the data acquisition and processing system. Radiometers are recalibrated at least annually with reference instruments traceable to the World Radiometric Reference (WRR).

太阳能辐射研究实验室（Solar Radiation Research Laboratory，简称SRRL）于1981年在美国太阳能研究所（现美国国家可再生能源实验室，National Renewable Energy Laboratory，简称NREL）成立，旨在开展太阳能资源连续监测、太阳总辐射计（pyranometer）与直接辐射计（pyrheliometer）的户外校准，并对商用仪器进行性能表征。该实验室为户外试验场，坐落于俯瞰丹佛市的南塔台山（South Table Mountain）——一座全年均可获得优质太阳辐射照射的台地。其基线测量系统最初仅以5分钟间隔采集水平总辐照度、直接法向辐照度与水平散射辐照度三类基础数据，如今已可实现1分钟间隔的130余项数据要素采集，相关数据可通过测量与仪器仪表数据中心网站获取。数据来源涵盖水平总辐照度、直接法向辐照度、水平散射辐照度（由遮光带式与跟踪圆盘式辐射计采集）、倾斜面总辐照度、反射太阳辐照度、紫外线（ultraviolet）、红外（infrared，含上行与下行波段）、光度辐射计（photometric radiometers）与光谱辐射计（spectral radiometers）数据、天空成像数据，以及多层级地面气象参数（包括气温、相对湿度、气压、降水量、积雪覆盖、风速与风向）。数据质量控制与评估工作包括每日（周一至周五，M-F）的仪器维护，同时基于冗余仪器实时核查与采用美国国家可再生能源实验室的SERI-QC方法开展内部一致性检验，实现自动化数据质量管控。数据采集与处理系统将自动生成电子邮件，向运维人员通报设备故障情况。所有辐射计每年至少采用可溯源至世界辐射基准（World Radiometric Reference，简称WRR）的标准仪器进行一次重新校准。
