Plot Description:

This plot presents a time series of Aridity Index. This index computes the standardized high temperature departure subtracted by the standardized precipitation departure. For the purposes of this plot, this index is computed daily over a trailing period of days of your choice. The climatology is based on the present period of record statistics. You can optionally plot this index for two other period of days of your choice. Entering '0' will disable additional lines appearing on the plot.
You can also optionally generate this plot for the same period of days over different years of your choice. When plotted over multiple years, only "Number of Days #1' is considered. An additional year is plotted representing the best root mean squared error fit to the selected year's data.

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!
