Plot Description:

Departure from climatology metrics have an annual signal that is a function of the climatology. This plot shows the distribution of departure values.

SPI is the standardized precipitation index. This is computed by using the NCEI 1991-2020 climatology to provide the average accumulation and the observed data to provide the standard deviation.

The Minimum Possible value presented is a function of the statistical metric being computed. For example, if the climatology accumation is 2 inches, the max negative departure can only be two inches.


Based on a sampling of recent timings for this application, plot generation time has averaged 4 seconds. Hold on for the plot is generating now!
