收藏资源简介:
该数据集名为“Données changement climatique - SQR (Séries Quotidiennes de Référence)”,专注于气候变化相关数据,具体为参考日序列(SQR)。SQR是从气象站选取的每日气候数据序列,基于均质化结果构建,以确保数据在给定时间段内的可靠性。数据选择考虑了多种因素,包括月序列中的均质性断裂、应用于月序列的校正幅度以获取均质化月序列、SQR期间的数据缺失率、测量站点的连续位移(水平和海拔方向)以及测量站参考编号的连续性(尽管多个站点的数据可能被合并以形成均质化月序列)。数据经过气候学控制检查。技术信息方面:数据以压缩CSV格式提供,覆盖法国本土和海外领土;提供的参数包括降水(RR)、最低温度(TN)和最高温度(TX);文件中包含气象站在数据文件创建时的状态(开放或关闭)信息;SQR数据最早从1991年开始;文件每年更新一次。数据集包含六个子集,分别对应不同参数和地区组合,例如“liste_sqr_rr_om”表示海外降水数据,“liste_sqr_tx_metro”表示本土最高温度数据等。
The dataset is titled Données changement climatique - SQR (Séries Quotidiennes de Référence), focusing on climate change-related data, specifically the Reference Daily Series (SQR). SQR consists of selected daily climatological data from weather stations for a given period, constructed based on homogenization results to ensure data reliability. The selection process considers multiple factors, including homogeneity breaks in monthly series, the amplitude of corrections applied to monthly series to obtain homogenized monthly series, the rate of missing data during the SQR period, successive displacements of measurement stations (horizontally and in altitude), and the continuity of a station reference number (although data from multiple stations may be merged to form the homogenized monthly series). The data has undergone climatological control checks. Technical information: The data is provided in compressed CSV format for metropolitan France and overseas territories; parameters include precipitation (RR), minimum temperatures (TN), and maximum temperatures (TX); files indicate the status of the weather station (open or closed) at the time of dataset creation; SQR data starts no later than 1991; files are updated annually. The dataset includes six subsets corresponding to different parameter and region combinations, such as liste_sqr_rr_om for overseas precipitation data and liste_sqr_tx_metro for metropolitan maximum temperature data.
