Meteorological observations at Lincoln: 1997

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。一份新西兰国家水与大气研究所（NIWA）报告（Mullan, A.B; Stuart, S.J; Hadfield, M.G; Smith, M.J (2010). 《NIWA“七站点”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，以及为统一不同站点间观测数据所开展的整合工作。目前尚未明确本次观测的具体站点，因为我们尚未找到其与NIWA存档记录的对应匹配关系。该数据集最初以.DAT格式存储，本次上传既保留了原始.DAT文件，同时也将数据进行标准化处理并转换为.csv格式。表头说明：原始.DAT文件未包含表头信息，通过配套的旧数据处理程序解析，绝大多数表头已可还原至.csv文件中，但仍有一列标注为"unknown"（未知列）。缺失数据处理：在原始.DAT文件中，根据不同场景，缺失的观测值分别以0、-9、-99或（云量项为9）进行记录；在转换后的.csv文件中，这些缺失值已被移除并留空。单位推测：各观测项的单位大概率如下：* 太阳辐射：MJ/m²（兆焦每平方米）* 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，以天空被云覆盖的八分之一为单位计量）* 风程：千米* 水汽压：Pa（帕斯卡）
