Satellite and ground observations began Aug. 1. Pre-inspection test flights are scheduled to begin Aug. 9 and the field campaign is expected to run through Sept. 30.
"Black carbon in soot is a major contributor to global warming," said Ramanathan. "By determining the effects of soot reductions during the Olympics on atmospheric heating, we can gain much needed insights into the magnitude of future global warming."
Ramanathan's team has revolutionized the gathering of atmospheric data through the use of AUAVs that enable researchers to form dimensional profiles of clouds and other atmospheric masses at relatively low cost. The scientists conducted their first successful experiment using AUAV data in the skies over the Indian Ocean during the 2005-2006 Maldives AUAV Campaign. Currently the Scripps researchers are also using the aircraft in the California AUAV Air Pollution Profiling Study, a nine-month-long survey of air pollution over Southern California.
In previous studies, meteorological data gathered by the aircraft helped demonstrate that atmospheric brown clouds can diminish the solar radiation that reaches Earth's surface, warm the atmosphere at low altitudes and disrupt cloud formation. With CAPMEX, scientists hope to improve their ability to deliver such assessments of particulate pollution effects more rapidly and enhance their value as a policymaking tool.
Miniaturized instruments on the aircraft measure a range of properties such as the quantity of soot and size of the aerosols upon which cloud droplets form. The instruments also record variables such as temperature, humidity and the intensity of sunlight that permeates clou
