中国0.25°分辨率生长期长度数据集（1948-2016年）

该数据集为中国范围生长期长度数据，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 is the growing season length data across China, with a spatial resolution of 0.25° and a temporal coverage from 1948 to 2016. The data is 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 calculated using the extreme climate indices published by the World Meteorological Organization (WMO). The spatial coverage of this dataset includes the main land areas of China (including Hong Kong, Macao and Taiwan regions), excluding regions such as the South China Sea reefs and atolls. The CSV data can be opened with software such as Microsoft Excel. The first column contains latitude values, the second column contains longitude values, and the third column and onwards are the calculated index values for each year. The TIFF data uses the WGS84 coordinate system. Each index file includes 69 bands corresponding to the years 1948 to 2016, and can be opened with software such as ENVI.
