Meteorological observations at Lincoln: 2006

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）的一篇报告由Mullan, A.B、Stuart, S.J、Hadfield, M.G、Smith, M.J 于2010年撰写：《NIWA“七站点”温度序列评估报告》，收录于NIWA信息系列第78号，第129-154页。该报告记录了多项林肯地区的气象观测数据，以及为协调不同站点间数据标准所开展的工作。目前尚未明确本次观测对应的具体站点，因为我们尚未找到与NIWA现有记录的对应匹配关系。

本数据集最初以.DAT格式存储。现已保留原始格式上传该数据集，同时也将其标准化并转换为.csv格式。

表头说明：原始.DAT文件未设置表头信息。通过原配套使用的老旧数据处理程序对数据进行解析，可恢复其中绝大多数表头，但仍有一列标注为"未知"。

缺失数据处理：.DAT文件中，根据观测场景的不同，缺失的测量值分别以0、-9、-99记录；云量数据的缺失值则以9记录。在转换后的.csv文件中，此类缺失值已被移除并留空。

单位说明（均为推测）：
* 太阳辐射：大概率为兆焦每平方米（MJ/m²）
* 气温：摄氏度（早年数据可能由华氏度转换而来）
* 降雨量：毫米
* 云量：八分云量（oktas，即云量以天空被云覆盖的八分之一比例为单位）
* 风程：千米
* 水汽压：大概率为帕斯卡（Pa）
