中国华北平原逐日1公里体感温度数据集（HiTIC-NCP，2003-2020）

中国华北平原逐日高空间分辨率体感温度数据集（HiTIC-NCP）包括近地表气温（Surface Air Temperature, SAT）和 11 个常用的体感温度指数：室内表观温度（indoor Apparent Temperature，ATin）、室外荫蔽处表观温度（outdoor shaded Apparent Temperature，ATout）、不舒适指数（Discomfort Index，DI）、有效温度（Effective Temperature，ET）、酷热指数（Heat Index，HI）、湿热指数（Humidex，HMI）、修正的不舒适指数（Modified Discomfort Index，MDI）、净有效温度（Net Effective Temperature，NET）、简化湿球黑球温度（simplified Wet Bulb Globe Temperature，sWBGT）、湿球温度（Wet-Bulb Temperature，WBT)、以及风寒温度（Wind Chill Temperature，WCT）。 该数据集空间分辨率高达1 km×1 km，时间分辨率为日尺度，覆盖了2003年1月至2020年12月的华北平原地区。HiTIC-NCP数据集中12个体感温度指数的总R2、平均绝对误差、均方根误差分别为0.987、0.970°C和1.292°C。 该数据集以年为单位存储为NetCDF格式数据，单年数据中共包含该年逐日体感温度指数栅格图像。HiTIC-NCP数据集体感温度单位为0.01摄氏度（°C），为节省存储空间，温度数值以整数数据类型（Int16）存储，在使用时需将其除以100。该数据集采用World Geodetic System 1984 (WGS84) 地理坐标系。如果您在使用HiTIC-NCP数据集时有任何问题，请直接联系数据集制作者：李翔（[e-mail]）、罗明（[e-mail]）、赵涌泉 （[e-mail]）。有关 HiTIC-NCP 数据集生成过程及其准确性评估的更多详细信息，请参阅：

Daily High Spatial Resolution Human Thermal Index Dataset over the North China Plain (HiTIC-NCP) includes surface air temperature (SAT) and 11 commonly used human thermal indices: indoor Apparent Temperature (ATin), outdoor shaded Apparent Temperature (ATout), Discomfort Index (DI), Effective Temperature (ET), Heat Index (HI), Humidex (HMI), Modified Discomfort Index (MDI), Net Effective Temperature (NET), simplified Wet Bulb Globe Temperature (sWBGT), Wet-Bulb Temperature (WBT), and Wind Chill Temperature (WCT). This dataset has a spatial resolution of up to 1 km × 1 km and a temporal resolution of daily scale, covering the North China Plain from January 2003 to December 2020. The overall R², mean absolute error (MAE), and root mean square error (RMSE) of the 12 human thermal indices in the HiTIC-NCP dataset are 0.987, 0.970 °C, and 1.292 °C, respectively. This dataset is stored in NetCDF format on an annual basis, with each annual file containing the daily raster images of human thermal indices for that year. The thermal index values in the HiTIC-NCP dataset are stored in units of 0.01 °C. To save storage space, the temperature values are saved as Int16 integer data type and need to be divided by 100 during usage. This dataset uses the World Geodetic System 1984 (WGS84) geographic coordinate system. If you have any questions when using the HiTIC-NCP dataset, please contact the dataset creators directly: Xiang Li ([e-mail]), Ming Luo ([e-mail]), and Yongquan Zhao ([e-mail]).
