3B Precipitation Processes and Observations for Atmospheric, Land Surface, and Hydrological Modeling I

Monday, 13 January 2025: 1:45 PM-3:00 PM
210 (New Orleans Ernest N. Morial Convention Center)
Hosts: (Joint between the 39th Conference on Hydrology; and the Second Symposium on Cloud Physics )
Cochairs:
Viviana Maggioni, George Mason University, Civil, Environmental Engineering, Fairfax, VA; Youcun Qi, Applied Weather Associates, NOAA/PSL, Monument, CO; Samantha Hartke, Univ. of Wisconsin–Madison, Civil and Environmental Engineering, Madison, WI and Zhe Zhang, Chinese Academy of Sciences, IGSNRR, Beijing, Beijing

This precipitation session focuses on precipitation observation and process understanding, modeling, estimation across spatiotemporal scales, advanced statistical techniques including artificial intelligence (AI)-based methods used to produce, analyze, and/or visualize precipitation data, and applications of in-situ and remotely sensed precipitation products. Process understanding and observational development topics include, but are not limited to (1) precipitation processes and modeling in coupled or uncoupled model systems; (2) improved assimilation algorithms leveraging precipitation process understanding; (3) recent development pertaining to fusion and downscaling of precipitation products; while applications could include: (4) assimilation of precipitation and precipitation-related variables in weather or water models; (5) impact of uncertainties associated with precipitation observations on hydrologic design and modeling or other modeling applications which ingest precipitation data, (6) assessment of precipitation variability, across spatiotemporal scales.

Submitters:  Andrew J. Newman, NCAR, Boulder, CO; Viviana Maggioni, Civil, Environmental Engineering, George Mason University, Fairfax, VA; Youcun Qi, IGSNRR, Chinese Academy of Sciences, Beijing, China; Samantha Hartke, Research Applications Laboratory, NCAR, Boulder, CO and Zhe Zhang, Shenzhen National Climate Observatory, Shenzhen, Guangdong Province, China
