PR Drought – Selected Soil and Water Parameters


This page provides links to maps of various soil and water related parameters, which can be used to determine areas affected by drought and how drought conditions may be changing from week to week or month to month.  The results were obtained using the water and energy balance model GOES-PRWEB.
