PODEX Experiment to reshape future of Atmospheric Science by getting a handle on aerosols and clouds

Polarimeter Definition Experiment (PODEX) in Southern California. The brightness, or “intensity,” and polarization of reflected light provide different information about the elements that make up a scene, apparent in this set of images collected by the Airborne Multiangle SpectroPolarimetric Imager (AirMSPI) during its maiden flight on Oct. 7, 2010, on the ER-2 over Palmdale, Calif.…

NASA on the sun: ‘…tiny variations can have a significant effect on terrestrial climate.”

Researchers have considered the possibility that the sun plays a role in global warming. From NASA GSFC:  Solar Variability and Terrestrial Climate In the galactic scheme of things, the Sun is a remarkably constant star.  While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our…

Some new climate surprises blow in with the dust

From NASA: Dust’s Warming Counters Half of its Cooling Effect Dust that routinely rises above the world’s deserts causes a more significant localized warming effect than previously thought, a new study based on NASA field research shows. In April 2008, atmospheric scientists set up camp in Zhangye, a semi-arid region between China’s Taklimakan and Gobi…

Even NASA has gotten into the “Frankenstorm” meme

From NASA’s PR engine: NASA Sees Hurricane Sandy as the “Bride of Frankenstorm” Approaching U.S. East Coast NASA’s TRMM satellite revealed Hurricane Sandy’s heavy rainfall and the storm is expected to couple with a powerful cold front and Arctic air to bring that heavy rainfall to the Mid-Atlantic and northeastern U.S. Some forecasters are calling…

Cool pictures from space of recent CME event auroras

Overnight on October 4-5, 2012, a mass of energetic particles from the atmosphere of the Sun were flung out into space, a phenomenon known as a coronal mass ejection. Three days later, the storm from the Sun stirred up the magnetic field around Earth and produced gorgeous displays of northern lights. NASA satellites track such…
