The Marine Cloud Brightening Project is an open, international collaboration of atmospheric scientists and other experts to advance understanding of cloud responses to aerosol particles - a critical part of understanding the climate, and a critical area in which human activities are thought to cause significant effects.
Clouds, Climate Impacts and Climate Intervention
Clouds reflect solar radiation (sunlight) back to space, producing cooling effects locally, and on the planet. The reflectivity of clouds increases as the number of water droplets inside the cloud increases and their size decreases, making the clouds brighter and longer lasting, reflecting sunlight and increasing cooling.
The Importance of Controlled Field Studies of Clouds & Aerosols
Our current lack of knowledge about how aerosols interact with clouds is hindering progress both in quantifying the amount of greenhouse warming being counter-balanced by aerosol increases, and in understanding the potential efficacy of marine cloud brightening.
The Marine Cloud Brightening Project
The Marine Cloud Brightening Project is an open, multi-institutional research collaboration within the Atmospheric Intervention Research (AIR) Program at the University of Washington. It operates in partnership with Palo Alto Research Center (PARC) where work is being undertaken to develop spray technology, and Pacific Northwest National Laboratory, a center of excellence for climate modeling.
