  • Brief Bio

    As the Project Scientist for the Global Precipitation Measurement (GPM) mission Dr. Jackson directs and coordinates all science team activities for GPM retrieval algorithms, ground validation, and both pure precipitation science and application science investigations. She also develops national and international partnerships, advocates for the mission, presents at conferences, education and outreach events, and prepares mission documentation. Because of her engineering background, Dr. Jackson provides a critical link between the project engineers/mission operations and the scientists using data.

    Gail Skofronick Jackson is a highly accomplished and well-regarded scientist for retrievals of ice particles in clouds. Dr. Jackson has been funded for this work as a PI for NASA Headquarters under the Precipitation Measurement Mission and CloudSat Programs.

    Dr. Skofronick Jackson is also the Laboratory Chief for the Mesoscale Atmospheric Processes (Code 612) Laboratory.

    Research Interests

    Active and Passive Retrievals of Falling Snow

    This work involves retrievals of ice particles in clouds and includes frozen particles above the melting layer and those that remain frozen to the Earth's surface (falling snow). Her work involves relating the underlying macro- and micro-physical state of the clouds to passive and active observations; developing methodologies to facilitate the estimation of falling snow and frozen particle characteristics; and improving measurements through recommending new instrumentation. Dr. Jackson was a key developer and lead of the GPM falling snow algorithm.
