Dai Palmer Drought Severity IndexEntry ID: noaa_cdc012
Abstract: Purpose -
PDSI from the Dai data. The documentation says, The Palmer Drought
Severity Index (PDSI) is devised by Palmer (1965) to represent the
severity of dry and wet spells over the U.S. based on monthly
temperature and precipitation data as well as the soil-water holding
capacity at that location. These ... data consist of the monthly PDSI over
global land areas from 1860 to 1995 derived using monthly surface air
temperature (from Hansen and Lebedeff, 1987 and updates) and
precipitation (from Dai et al., 1997) data. Soil-holding capacity was
fixed to climatological maps from Webb et al.(1993). More details can
be found in Dai et. al. (1998). Additional information including
references is available here.
