Observational Precipitation Data

The precipitation data can be stored in a two-dimensional array of 275162, where the x-axis stands for the longitude ranged from 120.0000°E to 122.0250°E and the y-axis stands for the latitude ranged from 21.8875°N to 25.3250°N. That is, the data of each storage cell represents the observational precipitation accumulated in the area of 0.0125°E width by 0.0125°N length. From the original observational precipitation data in the two-dimensional array, we can create the precipitation data with a lower resolution; for example, 0.0625° (the coverage of an observation about 6.5 km in one dimension) and 0.25° (the coverage of an observation about 26 km in one dimension). In these lower resolutions, we can take an average of the original observational precipitation data in the storage cells as the data stored in the corresponding larger cells. This conversion is designed to acquire the input precipitation data for generating the output data with a desired higher resolution by use of a deep learning model. It is guaranteed that the input-output pair of the precipitation data has the same rainfall values.
