climdex.sdii
computes the climdex index SDII, or Simple Precipitation
Intensity Index. This is defined as the sum of precipitation in wet days
(days with preciptitation over 1mm) during the year divided by the number of
wet days in the year.
A vector containing the value of the index for each year.
fclimdex rounds to 1 decimal place, whereas climdex.sdii does not. This results in some small differences.
