Photos of the Day: NASA Validates Global Satellites’ Accuracy

Using everything from a customized DC-8 jetliner to ground radars to four-inch rain gauges, scientists are fanning out across one of the soggiest places in the United States this month to measure raindrops and snowflakes like never before.

Led by NASA and the University of Washington, the field experiment on the Olympic Peninsula attempts to validate, on the ground, how well global satellites measure precipitation from space, which is crucial for areas of the world that lack rain gauges or other equipment.

The four-month long OLYMPEX project will collect detailed atmospheric data — right down to the size of raindrops — that fall over the ocean, along the coast, in the foothills and the rugged Olympic Mountains. Ground instruments have already started collecting data and NASA’s DC-8, a flying science laboratory, arrives in Washington state this week.
