The view from an ozone balloon floating 100,000 feet above the Colorado Front Range. NOAA scientists based in Boulder, Colorado launch weekly balloons from sites all around the globe to monitor stratospheric ozone concentrations. Floating to over twice the altitude of commercial airliners, the curvature of Earth and inky black of space are clearly visible.
