NASA Flies to Africa to Study Climate Effects of Smoke on Clouds
NASA scientists and two research aircraft are on their way to a unique natural laboratory off the Atlantic coast of southwest Africa to study a major unknown in future climate prediction.
The coast of Namibia is one of three places on Earth with persistent low-level clouds, and the only such location with a steady supply of tiny aerosol particles in the form of smoke from inland fires that mix with the clouds. NASA's Observations of Aerosols Above Clouds and their Interactions (ORACLES) mission will observe and measure how these particles interact with clouds and change their ability to warm or cool the planet.
"This is the perfect natural laboratory to study aerosol-cloud interactions, which are some of the largest uncertainties in the prediction of future climate," said Jens Redemann, ORACLES principal investigator at NASA's Ames Research Center in Moffett Field, California.
Some aerosols, such as dust and sea salt, have a natural origin. But others, such as soot and smoke released by fires and industry, are the result of human activities. Once aerosols enter the atmosphere, they can cause either a warming or cooling effect.
