Summary
These data represent simulated ecological drought conditions for current climate, and for future climate represented by all available climate models at two time periods during the 21st century. These data were used to: 1) describe geographic patterns in ecological drought under historical climate conditions, 2) quantify the direction and magnitude of change in ecological drought, 3) identify areas and ecological drought metrics with projected changes that are robust across climate models, defined as drought metrics and locations where >90% of climate models agree in the direction of change.

To enhance assessments of long-term climate change impacts in dryland ecosystems, this work identified robust changes in ecologically relevant drought for dryland vegetation. Recognizing the importance of soil moisture, we defined and quantified several drought metrics designed to represent the severity of drought conditions with demonstrated impacts on dryland plants. Specifically, we examined drought metrics that represent soil moisture deficiency, in combination with high temperature conditions, including chronic long-term drought stress driven by soil moisture deficiency, extreme short-term drought stress emerging from low soil moisture and high temperatures, and seasonal droughts defined by limited soil moisture during different times of year.
