These images compare the Yukon River near the village of Eagle on May 3 (left) and May 5, 2015 (right). White areas show ice and the brown areas, open water. International Arctic Research Center researcher Jessica Cherry created this image by taking high definition photos from an airplane and merging them together by using a 3-D image-processing program.

University of Alaska Fairbanks researcher Jessica Cherry has been flying over Alaska rivers and taking photographs for the National Weather Service’s Riverwatch program, which monitors rivers with a risk of flooding.

Her images capture more details than products derived from satellites.

Cherry, a hydrologist at the �� International Arctic Research Center, takes high-definition photos of the rivers with a camera, shooting through a port in a plane. She then merges them together by using a 3-D image-processing software program.

Cherry shares these images with the National Weather Service, which enhances the agency’s real-time monitoring. The images also provide its River Forecast Center with a detailed record of the breakup process, which can be used to improve future forecasts.

Scientists’ research is not limited to publications in scientific journals, Cherry noted. “We also do very hands-on work that can be used in near-real time to help our agencies make better decisions for communities.”
