中国0.25°分辨率热夜日数数据集（1948-2016年）

该数据集为中国范围热夜日数数据，空间分辨率为0.25°，时间为1948-2016年。数据格式为csv和tif格式。该数据集是根据Princeton 大学发布的Princeton Global Forcings全球0.25°气候数据集，基于WMO发布的极端气候指标计算生成的。本数据集包含的地理空间范围是全国主要陆地（包含港澳台地区），不含南海岛礁等区域。
csv数据可使用excel等软件打开，第一列为纬度值，第二列为经度值，第三列开始为各年的指标计算值。Tif数据为WGS84坐标，每个指标文件包括69个波段，对应1948-2016年，可以用ENVI等软件打开。

This dataset provides the annual number of tropical nights across China, with a spatial resolution of 0.25° and a temporal range of 1948 to 2016, available in CSV and TIFF formats. This dataset is generated based on the Princeton Global Forcings global 0.25° climate dataset released by Princeton University, and computed using the extreme climate indices published by the World Meteorological Organization (WMO). The geographic coverage of this dataset includes the main terrestrial areas of China (including Hong Kong, Macao and Taiwan regions), excluding regions such as the South China Sea reefs and islets. The CSV data can be opened using software such as Excel: the first column contains latitude values, the second column contains longitude values, and columns starting from the third column represent the index calculation values for each year. The TIFF data uses the WGS84 coordinate system, with each index file consisting of 69 bands corresponding to the years 1948–2016, and can be opened with software such as ENVI.
