资源简介:

The data collection consists of eleven datasets of atmospheric krypton-85 activity concentrations with 4 datasets from monitoring stations in the northern hemisphere ("Early Measurements NH", "Freiburg", "Schauinsland" and "Jungfraujoch") and 7 datasets from monitoring stations in the southern hemisphere ("Adelaide", "Antarctica", Cape Grim", "Cape Point", "Darwin", "Tahitit" and "Terre-Adelie"). "Adelaide" start: July 2015; end: ongoing (June 2020); number of measurements: 255; location: Adelaide, Australia; "Antarctica" start: June 1983; end: January 2008; number of measurements: 415; location: near Neumayer station, Antarctica; "Cape Grim" start: April 1987; end: July 1996; number of measurements: 166; location: Tasmania, Australia; "Cape Point" start: August 1985; end: October 1997; number of measurements: 415; location: Cape Point, South Africa; "Darwin" start: August 2007; end: May 2010; number of measurements: 120; location: Darwin, Australia; "Early Measurements NH" start: December 1959; end: May 1976; number of measurements: 204; location: various monitoring stations in the northern hemisphere; "Freiburg" start: June 1973; end: ongoing (July 2020); number of measurements: 2386; location: Freiburg, Germany; "Jungfraujoch" start: January 1990; end: ongoing (June 2020); number of measurements: 1547; location: Berner Alps, Switzerland (3500 m a.s.l); "Schauinsland" start: February 1976; end: ongoing (July 2020); number of measurements: 2386; location: near Freiburg, Germany (1200 m a.s.l); "Tahiti" start: August 1969; end: November 1976; number of measurements: 18; location: Tahiti, French Polynesia; "Terre-Adélie" start: March 1968; end: October 1977; number of measurements: 32; location: eastern Antarctica; All measurements were conducted via decay counting in gas proportional counters with a measurement uncertainty of about 3%. However, for the datasets "Tahiti" and "Terre-Adélie" no errors were given in the original publications and a conservative estimate of 10% measurement uncertainty was taken. Most of the data has been published already and the sources accessible via the internet are found in the reference section.

Suckow, „Krypton-85 datasets of the northern and southern hemisphere collected over the past 60 years,“ Data in Brief, in Press. The entire data collection is analysed in: A. Kersting, C. Schlosser, A. Bollhöfer und A. Suckow, “Evaluating 5 decades of atmospheric 85Kr measurements in the southern hemisphere to derive an input function for dating water and ice with implications for interhemispheric circulation and the global 85Kr emission inventory.“ Journal of Environmental Radioactivity, in Press.

本数据集汇集了11组大气氪-85(krypton-85)活度浓度实测数据集,其中4组源自北半球监测站点,分别为“Early Measurements NH”、“Freiburg”、“Schauinsland”与“Jungfraujoch”,剩余7组源自南半球监测站点,分别为“Adelaide”、“Antarctica”、“Cape Grim”、“Cape Point”、“Darwin”、“Tahiti”与“Terre-Adélie”。 "Adelaide" 起始监测时间:2015年7月; 终止监测时间:持续开展至今(截至2020年6月); 有效测量次数:255次; 监测地点:澳大利亚阿德莱德市; "Antarctica" 起始监测时间:1983年6月; 终止监测时间:2008年1月; 有效测量次数:415次; 监测地点:南极洲诺伊迈尔站附近; "Cape Grim" 起始监测时间:1987年4月; 终止监测时间:1996年7月; 有效测量次数:166次; 监测地点:澳大利亚塔斯马尼亚州; "Cape Point" 起始监测时间:1985年8月; 终止监测时间:1997年10月; 有效测量次数:415次; 监测地点:南非开普角; "Darwin" 起始监测时间:2007年8月; 终止监测时间:2010年5月; 有效测量次数:120次; 监测地点:澳大利亚达尔文市; "Early Measurements NH" 起始监测时间:1959年12月; 终止监测时间:1976年5月; 有效测量次数:204次; 监测地点:北半球多座监测站点; "Freiburg" 起始监测时间:1973年6月; 终止监测时间:持续开展至今(截至2020年7月); 有效测量次数:2386次; 监测地点:德国弗赖堡市; "Jungfraujoch" 起始监测时间:1990年1月; 终止监测时间:持续开展至今(截至2020年6月); 有效测量次数:1547次; 监测地点:瑞士伯尔尼阿尔卑斯山,海拔3500米(a.s.l.); "Schauinsland" 起始监测时间:1976年2月; 终止监测时间:持续开展至今(截至2020年7月); 有效测量次数:2386次; 监测地点:德国弗赖堡附近,海拔1200米(a.s.l.); "Tahiti" 起始监测时间:1969年8月; 终止监测时间:1976年11月; 有效测量次数:18次; 监测地点:法属波利尼西亚大溪地; "Terre-Adélie" 起始监测时间:1968年3月; 终止监测时间:1977年10月; 有效测量次数:32次; 监测地点:南极洲东部区域; 所有实测数据均通过气体正比计数器(gas proportional counters)开展衰变计数(decay counting)获取,整体测量不确定度(measurement uncertainty)约为3%。但“Tahiti”与“Terre-Adélie”两组数据集的原始文献未提供误差数据,因此采用10%的保守估计值作为其测量不确定度。 绝大多数数据集已公开发表,可通过互联网获取的相关文献来源详见参考文献章节。本数据集的详细说明与完整参考文献列表可参见: A.
