Synopsis
Using the SOHO Michelson Doppler Interferometer (MDI), scientists can use a process called Time-Distance helioseismology to determine temperatures and fluid flows under the surface of the Sun. Note: Zoom into the sunspot and reveal temperature and flow profiles revealed by time-distance helioseismology. Animator: Tom Bridgman (GST). Scientist: Junwei Zhao (Stanford University), Alexander G. Kosovichev (Stanford University). Platforms/Sensors/Data Sets: SOHO/Michelson Doppler Interferometer (MDI).
