"BELTSVILLE, Md. — NASA plans to launch a new satellite next year that will help scientists fill in a gap in their understanding of global warming: the role of clouds and airborne particles.
The satellite Glory, targeted for launch next June, will give scientists a much better tool to measure particles than any satellite so far. The particles, known as aerosols, are bits of things such as dust and smog.
"Undoubtedly, greenhouse gases cause the biggest climatic effect. But the uncertainty in the aerosol effect is the biggest uncertainty in climate at the present," said Michael Mishchenko, the Glory project scientist at the Goddard Institute for Space Studies."
