Spatial calculation of the Standardized Precipitation Index

The Standardized Precipitation Index (SPI) is one of the metrics used to assess drought conditions. Because it only requires precipitation data and is relatively simple to calculate, it has gained widespread application. In this study, we calculated the SPI over a six-month timescale for a specific location, which revealed a clear alternation between wet (blue) and dry (red) periods.
