Meteorological observations at Lincoln: 2000

Lincoln meteorological observations have been taken at a range of sites over the years. A NIWA report (Mullan, A.B; Stuart, S.J; Hadfield, M.G; Smith, M.J (2010). Report on the Review of NIWA's 'Seven-Station' Temperature Series. NIWA Information Series No. 78. pp.129-154) records a number of these along with the work undertaken to reconcile the data between different sites. It is not yet clear which site(s) these measurements were taken at as we have not yet identified a correspondence with NIWA's records.The datasets had been stored as .DAT files. The .DAT files have been uploaded as is, and also standardised and converted into .csv format.Headers: The original .DAT files were stored without headers. Most of these could be recovered for the .csv by running the data through an old program that had been used in conjunction with the data, but one column remains "unknown".Missing data: In the .DAT files, missing measurements are variously recorded, depending on context, as 0, -9, -99 or (in the case of Cloud cover) 9. In the .csv these values have been removed and left blank.Units are most likely:* solar radiation - probably MJ/m2 (megajoules per square metre)* temperatures - Celsius (in early years possibly converted from an original measurement in Fahrenheit)* rainfall - millimetres* cloud - oktas (eighths of the sky taken up by cloud)* wind run - kilometres* vapour pressure - probably Pa (pascals)Lincoln meteorological observations have been taken at a range of sites over the years.

多年来，林肯地区的气象观测在多个站点开展。新西兰国家水与大气研究所（NIWA）于2010年发布的报告（Mullan, A.B; Stuart, S.J; Hadfield, M.G; Smith, M.J. 《NIWA“七站”温度序列评估报告》，NIWA信息丛书第78号，第129-154页）记录了其中多项观测数据，以及为协调不同站点间数据所开展的相关工作。目前尚未明确本次使用的观测数据具体源自哪些站点，因为尚未能将其与NIWA的存档记录建立对应关联。
本次数据集最初以.DAT格式存储。我们已直接上传原始.DAT文件，同时也将数据标准化并转换为.CSV格式。
表头信息：原始.DAT文件未存储表头内容。通过使用早年配套处理该数据的旧程序，我们已恢复了绝大多数.CSV文件的表头，但仍有一列信息暂未明确，标记为"unknown"。
缺失数据处理：在原始.DAT文件中，根据场景不同，缺失的观测值分别以0、-9、-99或（针对云量观测）9进行标记。在转换后的.CSV文件中，这些标记值已被移除，对应位置留空。
各观测项的单位推测如下：
* 太阳辐射：推测为兆焦耳每平方米（MJ/m²）
* 气温：摄氏度（早期数据可能由华氏度转换而来）
* 降雨量：毫米
* 云量：八分仪（oktas，即云量占天空总覆盖面积的八分之一比例）
* 累计风速：公里
* 水汽压：推测为帕斯卡（Pa）
