That is one of the reasons that Schohr is helping to gather data on grazing and invasive weeds for scientific study on how drought is affecting the American West.

The past 20 years have been some of the driest conditions there on record, and while drought is a natural part of the climate cycle, droughts are becoming more frequent, severe, and pervasive as Earth’s atmosphere continues to warm due to climate change.

Tracking water in the U.S. closely is the U.S Drought Monitor, which includes NASA Earth science data and is developed through a collaboration between the University of Nebraska-Lincoln and other federal agencies. Schohr uses those maps for her weekly review of drought conditions. She also sends updates and photos to help refine those maps to scientists like Brian Fuchs, a climatologist at the National Drought Mitigation Center.

“What we’re able to do is bring in all of this data …
