西安历年均一化极端气温及其指数数据集（1960-2015）

长期的气象观测数据由于受到气象台站迁址等影响，造成观测数据记录的非均一性，使得对气候序列的长期趋势和极端气候事件的估计造成偏差。西安历年均一化极端气温及其指数数据集（1960-2015）是基于西安台站1960-2005年和泾河台站2006-2015年逐日最高温和最低温实测数据，参考渭南和蒲城气象台站实测数据，采用RHtest软件对西安、泾河气温序列进行均一性检验和订正的基础上，通过计算极端气温指标获得的。该数据集包括16项极端气温指数，分为4类：绝对指数（夏季日数SU、热夜日数TR、冰冻日数ID、霜冻日数FD）、相对指数（暖昼日数TX90、冷昼日数TX10、暖夜日数TN90、冷夜日数TN10）、极值指数（最高温最大值TXx、最高温最小值TXn、最低温最大值TNx、最低温最小值TNn）、持续指数（暖持续日数WSDI、冷持续日数CSDI、气温日较差DTR、生物生长季日数GSL）。数据集包括：（1）西安、泾河及其周围气象站点位置数据；（2）1960-2015历年西安极端气温观测数据；（3）1960-2015历年西安极端气温订正数据；（4）1960-2015历年西安观测极端气温绝对指数数据；（5）1960-2015历年西安订正极端气温绝对指数数据；（6）1960-2015历年西安观测极端气温相对指数数据；（7）1960-2015历年西安订正极端气温相对指数数据；（8）1960-2015历年西安原始极端气温极值指数数据；（9）1960-2015历年西安订正极端气温极值指数数据；（10）1960-2015历年西安原始极端气温持续指数数据；（11）1960-2015历年西安订正极端气温持续指数数据。数据集存储为1个Excel文件（.xlsx格式），数据量为38.2KB。该数据集的分析研究成果发表在《地理科学》2018年38卷3期。

Long-term meteorological observation data often suffer from inhomogeneity in records caused by factors such as relocation of meteorological stations, which leads to biases in the estimation of long-term trends of climate sequences and extreme climate events.
The Homogenized Extreme Temperature and Its Indices Dataset for Xi'an (1960-2015) is developed based on daily maximum and minimum temperature in-situ measured data from Xi'an station during 1960-2005 and Jinghe station during 2006-2015, with reference to measured data from Weinan and Pucheng meteorological stations. Homogenization test and correction were performed on the temperature sequences of Xi'an and Jinghe using the RHtest software, followed by calculation of extreme temperature indices.
This dataset includes 16 extreme temperature indices, divided into four categories:
1. Absolute indices: Summer days (SU), Tropical nights (TR), Icing days (ID), Frost days (FD)
2. Relative indices: Warm days (TX90), Cool days (TX10), Warm nights (TN90), Cool nights (TN10)
3. Extreme indices: Maximum of daily maximum temperature (TXx), Minimum of daily maximum temperature (TXn), Maximum of daily minimum temperature (TNx), Minimum of daily minimum temperature (TNn)
4. Duration indices: Warm Spell Duration Index (WSDI), Cold Spell Duration Index (CSDI), Diurnal Temperature Range (DTR), Growing Season Length (GSL)
The dataset contains the following contents:
(1) Location data of meteorological stations in Xi'an, Jinghe and their surrounding areas;
(2) Annual observed extreme temperature data of Xi'an from 1960 to 2015;
(3) Annual corrected extreme temperature data of Xi'an from 1960 to 2015;
(4) Annual observed absolute extreme temperature indices data of Xi'an from 1960 to 2015;
(5) Annual corrected absolute extreme temperature indices data of Xi'an from 1960 to 2015;
(6) Annual observed relative extreme temperature indices data of Xi'an from 1960 to 2015;
(7) Annual corrected relative extreme temperature indices data of Xi'an from 1960 to 2015;
(8) Annual extreme indices data calculated from raw temperature data of Xi'an from 1960 to 2015;
(9) Annual extreme indices data calculated from corrected temperature data of Xi'an from 1960 to 2015;
(10) Annual duration indices data calculated from raw temperature data of Xi'an from 1960 to 2015;
(11) Annual duration indices data calculated from corrected temperature data of Xi'an from 1960 to 2015.
The dataset is stored as a single Excel file in .xlsx format, with a total size of 38.2 KB. The analytical research results based on this dataset were published in *Scientia Geographica Sinica*, Volume 38, Issue 3, 2018.
