中国0.25°分辨率年降水量数据集（1948-2016年）

该数据集为中国范围年降水量数据，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 annual precipitation data within China, with a spatial resolution of 0.25° and a temporal range from 1948 to 2016, and is available in both CSV and TIFF formats.

It was developed based on the Princeton Global Forcings global 0.25° climate dataset released by Princeton University, through the calculation of extreme climate indicators issued by the World Meteorological Organization (WMO). The spatial coverage of this dataset covers all major terrestrial areas of China (including Hong Kong, Macau and Taiwan regions), excluding areas like the South China Sea reefs.

For the CSV-format data, it can be opened using software such as Excel. The first column stores latitude values, the second column stores longitude values, and the columns starting from the third one represent the calculated indicator values for each individual year.

As for the TIFF-format data, it adopts the WGS84 coordinate system. Each indicator file contains 69 bands corresponding to the years 1948 to 2016, and can be opened with software such as ENVI.
