Plot Description:

This application generates a heatmap of the frequency of a given drought classification. The classification is the minimal threshold, so if a location is in D3 classification drought, it would count as D0, D1, D2, and D3 for this analysis. The dates you specify are rectified to the previous Tuesday on which the USDM analysis is valid for.

Caution: This is an unofficial depiction of time duration of Drought Monitor classfication and due to complexities with how the grid analysis is done, the exact pixel location is nebulous. Having said that, it should be close!


Based on a sampling of recent timings for this application, plot generation time has averaged 7 seconds. Hold on for the plot is generating now!
