资源简介:
原始数据来源于中国气象数据网“中国地面气候资料日值数据集(V3.0)”提供的全国800多个观测站的日观测降水,通过对数据进行异常值剔除、空值插补等操作后,采用ANUSPLINE插值方法,将站点观测数据插值成分辨率为1km的格网数据,可以用于降水年际变化、干旱胁迫等分析。
The raw data is sourced from the daily observed precipitation records of more than 800 national meteorological stations, which are provided by the Daily Dataset of China Surface Climate Data (V3.0) on the China Meteorological Data Network. After performing preprocessing operations including outlier removal and missing value imputation, the station-based observation data is interpolated into grid data with a spatial resolution of 1 km using the ANUSPLINE interpolation method. This dataset can be applied to analyses involving interannual variation of precipitation and drought stress.
