湖北省标准化历年霾天气数据集（1961-2013）

利用湖北省76个气象观测站1961-2013年逐日能见度､相对湿度定时数据以及天气现象(霾和轻雾)人工观测数据，根据《霾的观测和预报等级》(QXT113—2010)相关标准，对湖北省霾日序列进行重建､订正，形成标准化序列｡然后，依据该标准化序列构建大范围持续性霾过程评估模型，进行相关统计和分析，得到湖北省标准化历年霾天气数据集(1961-2013)｡该数据集包括：（1）1961-2013年湖北省霾日数和霾过程的统计数据｡该统计包括：a) 年霾日数；b) 标准化序列的四季霾日数；c) 重度大范围持续性霾过程出现次数和最长持续日数｡（2）1961-2013年多年平均的湖北省年霾日数空间分布数据。（3）1961-2013年多年平均的湖北省标准化序列年霾日数空间分布数据。（4）1961-2013年多年平均的湖北省霾日数与标准化序列霾日数差值空间分布数据。（5）1961-2013年湖北省重度大范围持续性霾过程累积出现频次空间分布数据｡该数据集存储为.xls和.tif格式，一共由5个文件组成，数据量为561 KB(压缩为1个文件，145 KB)｡其中，栅格数据的空间分辨率为10 km｡该数据集的分析研究成果发表在《气象与环境学报》2016年第32卷第1期。

Using daily visibility, hourly relative humidity data and manual observational weather phenomenon data (haze and light fog) from 76 meteorological stations in Hubei Province during 1961-2013, and following the relevant standards of *Grade of Observation and Forecasting for Haze* (QX/T 113—2010), the haze day sequence of Hubei Province was reconstructed and revised to form a standardized sequence. Then, based on this standardized sequence, a large-scale persistent haze event assessment model was constructed, and relevant statistics and analyses were carried out to obtain the standardized annual haze weather dataset for Hubei Province (1961-2013). This dataset includes: (1) Statistical data of haze days and haze events in Hubei Province from 1961 to 2013. The statistics cover: a) Annual haze days; b) Seasonal haze days of the standardized sequence; c) Number of occurrences and maximum duration of severe large-scale persistent haze events. (2) Spatial distribution data of multi-year average annual haze days in Hubei Province from 1961 to 2013. (3) Spatial distribution data of multi-year average annual haze days of the standardized sequence in Hubei Province from 1961 to 2013. (4) Spatial distribution data of the difference between multi-year average haze days and haze days of the standardized sequence in Hubei Province from 1961 to 2013. (5) Spatial distribution data of cumulative occurrence frequency of severe large-scale persistent haze events in Hubei Province from 1961 to 2013. This dataset is stored in .xls and .tif formats, consisting of 5 files in total, with a total size of 561 KB (compressed into 1 single file of 145 KB). The spatial resolution of the raster data is 10 km. The research and analysis results of this dataset were published in *Journal of Meteorology and Environment*, Volume 32, Issue 1, 2016.
