The Climate and Radiation Branch at NASA's Goddard Space Flight Center supports a key NASA mission, namely, to understand and protect our home planet. We seek a better understanding of Earth's climate on all time scales, from daily, seasonal and interannual variability through changes on geologic time scales. Our research focuses on atmospheric measurement, numerical modeling, and climate analysis. We investigate atmospheric radiation, both as a driver for climate change and as a tool for the remote sensing of Earth's atmosphere and surface. The Branch research program seeks to better understand how our planet reached its present state, and how it may respond to future drivers, both natural and anthropogenic.

Using Volcanic Eruptions as Natural Laboratories to Study Climate Responses
May 4, 2008 — The Chaitén volcano in southern Chile erupted in the early morning of May 2, 2008 throwing copious amounts of pyroclastic material which, according to preliminary reports, reached well above 10km from the surface. No injuries were reported, but several towns were evacuated as a precautionary measure. A large area downwind covered by ash is posing a major risk to the local sheep and tourist industry.

Video featuring branch member appears in ScienCentral
April 28, 2008 — A 90-second video film story produced by ScienCentral was fed to ABC television stations on April 18 and posted on ScienCentral's web site. It describes recent research by branch member Tom Bell using TRMM satellite data that suggests that storm development in the southeast U.S. is intensified when anthropogenic pollution increases. The science news clip can be viewed here.

Goddard scientists use satellite to quantify the trans-Pacific transport of pollution aerosol
April 23, 2008 — In a new study published in the Journal of Geophysical Research – Atmospheres titled "A satellite-based assessment of transpacific transport of pollution aerosol", scientists from the Climate & Radiation Branch and the Laboratory for Atmospheres at Goddard Space Flight Center offer the first satellite-based estimate of the amount of pollution from East Asian and European forest fires, urban exhaust, and industrial production making its way to western North America. The satellite data suggest that 18 teragrams of pollution aerosol was exported to the northwestern Pacific Ocean and 4.5 teragrams reached North America annually from East Asia and beyond. The amount of pollution arriving in North America is equivalent to about 15 percent of local emissions of the U.S. and Canada.
