The Colorado Climate Center has completed this project to develop plant available water maps for Colorado using the Western Land Data Assimilation Systems, showing how much of the water in the soil is available for plant use. These maps are updated weekly and are used regularly in the Colorado Climate Center's weekly drought updates, monthly drought webinars, and monthly updates to the Colorado Water Availability Task Force.
The maps have been a useful complementary product to soil moisture percentile maps as they provide an understanding of where plant water is not just low but absent. Furthermore, these maps have been used in drought classification recommendations to the U.S. Drought Monitor, especially as a means of interpolating between long-term weather stations.
