Generate Annual Precipitation raster with CHIRPS Data (Rainfall) in Google Earth Engine (GEE)

In this tutorial, we delve into visualizing annual precipitation raster using CHIRPS (Climate Hazards Group InfraRed Precipitation with Station) data in Google Earth Engine. Join us as we step through the process of loading country boundaries, integrating CHIRPS data, and creating captivating visualizations.

1. Loading Country Boundaries: We begin by importing country boundaries data from the U.S. Department of State's LSIB dataset. Focusing on China, we filter and center the map view accordingly.
2. Inserting CHIRPS Data: Next, we incorporate CHIRPS precipitation data, specifically targeting pentad (5-day) intervals for the period between January 1, 2023, and January 1, 2024.
3. Reducing Image Collection: We streamline the image collection by summing the 365 daily raster, thus obtaining an annual precipitation raster.
4. Setting Visualization Parameters: To enhance clarity, we establish visualization parameters, defining minimum and maximum values along with a color palette to represent varying precipitation levels.
5. Adding the Map: Finally, we integrate the annual precipitation layer, clipped to the China region boundary, onto the map using our defined visualization parameters. This visually represents the distribution of annual precipitation across China for the specified time frame.
