SAFARI 2000 Surface Albedo and Radiation Fluxes at Mongu and Skukuza, 2000-2002

Top-of-the-canopy broadband albedo and radiation fluxes are calculated from measurements at the Mongu and Skukuza flux tower sites in southern Africa from March 2000 through December 2002. Data were collected by instrumentation deployed at the top of the 30 m tower in the Kataba Local Forest near Mongu, Zambia, and atop the 20 m tower at the Skukuza tower site in Kruger National Park, South Africa. At the Mongu site, Kipp and Zonen albedometers housing both upward- and downward-looking pyranometers were outfitted with clear and red domes to collect broadband albedo and radiation fluxes in the shortwave (SW) and near-infrared (NIR) wavebands, respectively. The data are mean values provided at 15-minute intervals for 2000-2002. At the Skukuza tower, Kipp and Zonen albedometers (also outfitted with clear and red domes) collected broadband albedo and radiation fluxes in the SW and NIR wavebands. In addition, a pyrgeometer was used to collect longwave radiation flux in thermal infrared (TIR) wavebands. The data at Skukuza are mean values provided at 30-minute intervals for 2000-2002, except for the TIR data, which are provided for 2001 and 2002 only. For both sites, photosynthetically active radiation can be calculated from measurements.The data are provided in comma-delimited ASCII files, with column headers. The SW and NIR data for both sites are provided in one file per year per site for 2000-2002. The Skukuza longwave data are provided separately, and for years 2001 and 2002 only.

本数据集收集了自2000年3月至2002年12月期间，在非洲南部蒙古和斯库库扎辐射塔站点进行的冠层顶部宽带反照率和辐射通量测量数据。数据通过在赞比亚蒙古附近卡塔巴局部森林30米高塔顶及南非克鲁格国家公园斯库库扎塔站点20米高塔顶部署的仪器获得。在蒙古站点，配备了向上和向下观测的比色辐射计的基普和宗森反照仪被安装了透明和红色穹顶，分别用于收集短波（SW）和近红外（NIR）波段内的宽带反照率和辐射通量。数据以2000-2002年间的15分钟间隔提供的平均值。在斯库库扎塔，基普和宗森反照仪（同样配备了透明和红色穹顶）收集了SW和NIR波段的宽带反照率和辐射通量。此外，还使用了辐射计收集热红外（TIR）波段的长时间辐射通量。斯库库扎的数据以30分钟间隔提供的平均值，2000-2002年提供，除TIR数据外，仅提供2001年和2002年的数据。对于两个站点，均可以通过测量数据计算光合有效辐射。数据以逗号分隔的ASCII文件格式提供，包含列标题。2000-2002年，每个站点每年提供一份包含SW和NIR数据的文件。斯库库扎的长波数据单独提供，仅限2001年和2002年。
