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.

Catching the August 1st Solar Eclipse from Orbit
August 24, 2008 — Every 99 minutes, the Earth-orbiting Terra satellite passes very close to the North and South Poles as it travels from north to south in daylight (late morning local time) and returns from south to north in darkness (before midnight local time). On August 1st, at about 9:40am GMT, it began a south-southwesterly daylight orbit from a location at 82 degrees north latitude above the Arctic Ocean (north of Siberia). During this orbit, the MODIS instrument aboard Terra viewed regions where the solar eclipse was total and other partially darkened areas. This image shows one affected orbit displayed in the foreground with prior and later orbits 99 minutes apart displayed in the background. The Earth's rotation carries the surface toward the east, so Terra appears to be stepping westward from orbit to orbit. Meanwhile the eclipse progressed toward the south-southeast allowing Terra to cross it's track just once. More on this Image

Branch Members Attend Meetings in Kenya and Tanzania
September 11, 2008 — Robert Cahalan with Charles Gatebe (UMBC-GEST) traveled to Nairobi, Kenya to attend the Greater Horn of Africa Climate Outlook Forum (GHACOF22) in Nairobi, Kenya. They also met with representatives of the Nairobi Education Department to discuss the GLOBE Program. Drs. Cahalan and Gatebe visited the Headmaster of the Starehe Boys Center in Nairobi and the Kiriti Secondary School in Nyeri, a rural village. In addition, they visited the Nairobi Aeronet site.

New Role for Branch Member
September 11, 2008 — Dr. Charles Ichoku was hired as a Research Physical Scientist with the Climate & Radiation Branch on August 31, 2008. Dr. Ichoku's research is focused on the global occurrence, distribution, radiative properties, and climate forcing effects of aerosols. He also devotes a large amount of time and effort to the study of fires and their emissions, which include radiative energy and smoke aerosol.
