Standardized Precipitation Index (SPI) has been generated for selected Environment Canada long-term climate stations located within the province of Ontario. SPI quantifies the precipitation deficit/surplus as an index for multiple time scales. SPI is provided for 1-month, 3-month, 6-month, 9-month, 12-month and 24-month time scales. The Standardized Precipitation Index data package is distributed as a Microsoft Access Geodatabase.
