Local Standardized Precipitation Index (SPI) for Hydro-climate Applications
SPI is an index used by National Drought Mitigation Center (NDMC) for climate monitoring, in particular, operational drought detection and triggers of the policy responses (Hayes et al. 1999). Currently, NDMC produces gauge-based monthly SPI for each U.S. climate division. The demo shows the PERSIANN data are expanded to produce local SPI based on the climate divisions long-term precipitation data.
SPI calculation requires long-term (> 30 yrs) precipitation data to derive Precipitation Probability Density Function (PDF) for an area. Based on the PDF, the dry-wet climate index-SPI is calculated from the past month’s precipitation.
