Unmanned Aircraft Measures Low Altitude Greenhouse GasesMoffett Field CA (SPX) Dec 09, 2011 For the first time, NASA researchers have demonstrated the use of an unmanned aerial vehicle (UAV) to collect very low altitude airborne measurements of greenhouse gases at several sites in California and Nevada. As Earth scientists strive to better understand sources and sinks of atmospheric greenhouse gases, a new aircraft capability developed at NASA Ames Research Center, Moffett Field, Calif. has the potential to provide critical measurements of carbon fluxes. The Sensor Integrated Envir ... read more |
