1960-2014年北京极端气温重建数据集

半个多世纪以来，由于气象站的变化，造成气象观测数据历史可比性存在一定的偏差。1960-2014年北京极端气温重建数据集是基于北京1960-2014年逐日最高温、最低温、平均气温实测数据，参考丰宁、怀来和廊坊气象站点的实测数据，采取RHtest方法对北京气温序列进行均一性检验和修订基础上组成的数据集。数据集汇集了16个极端气温指标，包括四大类：相对指数（冷昼日数TX10、冷夜日数TN10、暖昼日数TX90、暖夜日数TN90）、绝对指数（冰冻日数ID、霜冻日数FD、夏季日数SU、热夜日数TR）、极值指数（最高温极低值TXn、最低温极低值TNn、最高温极高值TXx、最低温极高值TNx）和持续指数（暖持续日数WSDI、冷持续日数CSDI、生物生长季GSL、气温日较差DTR），获得1960-2014年北京极端气温变化数据集。数据集包括：（1）北京及其周围的气象站点分布数据；（2）历年北京原始气温数据；（3）历年北京修订气温数据；（4）历年北京原始极端气温相对指数数据；（5）历年北京修订极端气温相对指数数据；（6）历年北京原始极端气温绝对指数数据；（7）历年北京修订极端气温绝对指数数据；（8）历年北京原始极端气温极值指数数据；（9）历年北京修订极端气温极值指数数据；（10）历年北京原始极端气温持续指数数据；（12）历年北京修订极端气温持续指数数据。该数据集存储为.xlsx格式，数据量为45KB。该数据集的分析研究成果发表在《地理科学》2015年35卷12期。

Over the past half-century, changes in meteorological stations have introduced certain inconsistencies in the historical comparability of meteorological observational data. The 1960–2014 Beijing Extreme Temperature Reconstruction Dataset was developed based on in-situ measured daily maximum, minimum and mean air temperature data from Beijing during 1960–2014, with reference to measured data from Fengning, Huailai and Langfang meteorological stations, and through homogeneity test and correction of Beijing’s air temperature series using the RHtest method. The dataset collects 16 extreme air temperature indices, divided into four categories: Relative indices (number of cool days TX10, number of cool nights TN10, number of warm days TX90, number of warm nights TN90), Absolute indices (number of icing days ID, number of frost days FD, number of summer days SU, number of tropical nights TR), Extreme value indices (minimum of daily maximum temperature TXn, minimum of daily minimum temperature TNn, maximum of daily maximum temperature TXx, maximum of daily minimum temperature TNx), and Persistence indices (warm spell duration index WSDI, cold spell duration index CSDI, growing season length GSL, diurnal temperature range DTR). The final 1960–2014 Beijing extreme air temperature change dataset was thus established. The dataset includes: (1) Distribution data of meteorological stations in and around Beijing; (2) Annual original air temperature data of Beijing; (3) Annual corrected air temperature data of Beijing; (4) Annual original relative extreme air temperature index data of Beijing; (5) Annual corrected relative extreme air temperature index data of Beijing; (6) Annual original absolute extreme air temperature index data of Beijing; (7) Annual corrected absolute extreme air temperature index data of Beijing; (8) Annual original extreme value index data of Beijing’s extreme air temperature; (9) Annual corrected extreme value index data of Beijing’s extreme air temperature; (10) Annual original persistence index data of Beijing’s extreme air temperature; (12) Annual corrected persistence index data of Beijing’s extreme air temperature. This dataset is stored in .xlsx format, with a total size of 45 KB. The analytical and research findings of this dataset were published in *Scientia Geographica Sinica*, Vol. 35, No. 12, 2015.
