The CHIRPS Pentad is the 5-day composite of rainfall at ~6 km spatial resolution. To compute this data, both satellite and ground values are considered. To read more about the methodology, visit nature.com
Using this image collection, we can filter all the images of the required year. To get a yearly rainfall we can reduce the collection using the reduce function with sum reducer. This will return a single global image where each pixel represents the total annual rainfall value in mm at that location.
