    Bottom Up or Top Down? Another Way to Look at an Air Quality Problem

    While not all countries have the financial wherewithal and capacity to deploy ground-based instruments for air-quality monitoring, and for some countries monitoring information is not available to the public, for example, through health advisories, another way exists to assess air pollution levels: through satellites.

    Hybrid Climate Data for East Africa

    In our latest video interview, climate scientist Tufa Dinku talks about his work on combining weather station data with satellite information to generate high-resolution data sets. These data could be used for making more accurate forecasts and can feed into other climate risk management activities, such as early-warning systems. With funding from Google.org, Dinku and…
