We explore the critical role of visualization and visual analytics in disaster management and medical research with Paul Navrátil and Jim Jeffers. Paul reveals TACC’s approach to recent weather crises, as well as their partnership with National Oceanic and Atmospheric Administration (NOAA) in hurricane forecasting. He also talks about their collaboration with the Open Science community in the national high-performance computing (HPC) mobilization effort to fight COVID-19. Jim unpacks the complexities of in-situ analysis, ray tracing, and line-of-sight physics. And they jam about the SOLAR Ray Tracing Consortium, Khronos* Group ANARI* Working Group, and more.
