The researchers used satellite images to calculate the long-term cloud cover over regions in the 30-45 degree latitudinal range based on how different types of vegetation interact with the atmospheric boundary. They found that clouds form more frequently over forested areas and had a greater cooling effect on Earth’s atmosphere. […]

Deep streams of data from Earth-imaging satellites arrive in databases every day, but advanced technology and expertise are required to access and analyze the data. Now a new system, developed in research based at the University of California, Berkeley, uses machine learning to drive low-cost, easy-to-use technology that one person […]
