introduction
The Geographic Remote Sensing Ecological Network combines the data of ground meteorological monitoring stations in various regions from 1951 to 2021, and uses the climate data spatial interpolation software Anusplin to predict the national annual rainfall distribution data results. The rainfall distribution map of various provinces, municipalities and autonomous regions in the country is obtained. The rainfall data product of various provinces, municipalities and autonomous regions in the country is one of the meteorological and climatic data products launched by the Geographic Remote Sensing Ecological Network. The product data has high accuracy and good quality.

Data Introduction
The average annual rainfall refers to the mean value obtained by dividing the sum of the annual rainfall in a certain place by the number of years, or the mean annual rainfall measured at multiple observation points in a certain place. The average annual rainfall is one of the important measures of a place's climate.
Rainfall data is of great significance for predicting and preventing flood disasters, forecasting and forecasting hydrology and water resources systems, agricultural crop production and ecological environment changes.
The geographic remote sensing ecological network combines the data of ground meteorological monitoring stations in various regions from 2000 to 2010, and uses the climate data spatial interpolation software Anusplin to predict the national annual rainfall distribution data results. The rainfall distribution map of various provinces, municipalities and autonomous regions in the country is obtained. The rainfall data product of various provinces, municipalities and autonomous regions in the country is one of the meteorological and climate data products launched by the geographic remote sensing ecological network platform. The product data has high accuracy and good quality.
The distribution of rainfall in Liaoning Province is characterized by decreasing from the coast to the inland, mainly showing the difference between the east and the west, and the rainfall is between 480-1452mm. In the east, Fushun, Benxi and Dandong are the areas with the most rainfall, all of which are above 1150mm. The areas with lower rainfall are Chaoyang City and Fuxin City, where the rainfall is less than 750mm.
