Abstract:
The Global Precipitation Measurement Mission (GPM) is nearing 10 years in operation, building a legacy of unprecedented advances in understanding the global distribution and characteristics of rain and snow. This is demonstrated through thousands of attributions in the scientific literature, public outreach and education, and real-time use by forecasters and decision makers. This presentation will focus on the evolution of the way we measure precipitation from space previous to, and throughout the GPM era, ranging from the GPM-Core satellite with coincident active and passive microwave observations, to the radiometer constellation, to the global products favored by users of the data. Innovations have also included adapting to variability in sensors and algorithms as well as improvements over land surfaces, typically more problematic for these types of retrieval techniques. Discussion will also include continuing challenges along with the outlook for the post-GPM era.
Biosketch:
Dr. Sarah Ringerud is a research meteorologist specializing in remote sensing and atmospheric science and the Deputy Project Scientist for the Global Precipitation Measurement Mission (GPM). Contributions to the field are focused on the development and innovation of satellite algorithms for microwave instruments.
Sarah holds a Ph.D. in Atmospheric Science with an emphasis on Remote Sensing from Colorado State University, where her dissertation focused on physically-based passive microwave precipitation retrieval over land. She also earned an M.S. in Atmospheric Science from the same institution and a B.S. in Atmospheric and Oceanic Sciences, with a second major in Mathematics, from the University of Wisconsin – Madison.
Currently serving as a Research Meteorologist at NASA Goddard Space Flight Center (GSFC), Sarah leads projects focused on the Global Precipitation Measurement Mission (GPM) and future mission concepts. Her expertise lies in satellite algorithm development, particularly for microwave instruments, and she actively collaborates with government and academic partners to advance the field of precipitation remote sensing. Sarah’s research interests span remote sensing, radiative transfer, the global hydrologic cycle, and atmospheric radiation. She has received numerous awards and fellowships for her work, including the UMD-ESSIC Best Paper of the Year Award, CSU Alumni Award, and the NASA Group Achievement Award for the Global Precipitation Measurement Mission.
In addition to her research endeavors, Sarah is an active member of professional organizations such as the American Meteorological Society (AMS), the American Geophysical Union (AGU), and the Institute of Electrical and Electronics Engineers Geoscience and Remote Sensing Society (IEEE-GRSS). She has presented her work at numerous domestic and international conferences and serves as a reviewer for multiple scientific journals.
