- Description:
- WRCC PDSI (drought index). Recent 10-year climatology for drought across the summer cycle, 2005-2014.The self-calibrated Palmer Drought Severity Index (scPDSI) is a locally calibrated index that estimates the severity of drought conditions relative to normal conditions measured for the region. This is one of the most frequently used standard measures of drought in the United States. Negative values indicate unusually dry conditions, with moderate drought indicated in the -2 to -3 range.
