2. Page 2LWS Teams Day JSOC Overview Primary goal: origin of solar variability The primary goal of the Helioseismic and Magnetic Imager (HMI) investigation is to study the origin of solar variability and to characterize and understand the Sun’s interior and the various components of magnetic activity. HMI produces data to determine the interior sources and mechanisms of solar variability and how the physical processes inside the Sun are related to surface and coronal magnetic fields and activity.

Page 18LWS Teams Day JSOC Overview Detail Example: Time-Distance Helioseismology Products Full-disk synoptic flow maps: –Area: from -60 to +60 deg in longitude and latitude (30x30 deg tracked regions, sampling TBD) –Depth: 0-30 Mm (~ 20 distances) –Cadence: 3 per day –Resolution: 0.2 deg per pixel –Comment: systematic errors for sound-speed maps may be too large; usefulness is unclear – suggestion: descope Carrington synoptic maps: –Central meridian flow maps made from the full-disk maps High-resolution flow and sound-speed maps of tracked AR –Area: 30x30 deg –Depth: 0-30 Mm –Cadence: 8 hours (with a 2-hour shift? Need to study this option) –Resolution: 0.06 deg/pixel –Track areas of all AR in NOAA from -60 to +60 longitude (including periods prior flux emergence and after disappearance) –Need matching vector magnetograms High-resolution flow and sound-speed maps of flaring AR –Area: 30x30 deg –Depth: 0-30 Mm –Cadence: 4 hours (with a 1-hour shift) –Resolution: 0.06 deg/pixel –Track AR with NOAA probability of X-class flare > 30% ? (need selection criteria) –Need corresponding high-cadence vector magnetograms Deep-focus flow maps –Keep as research topic, include in pipeline when ready. Additional funding/FTE required.

19. Page 19LWS Teams Day JSOC Overview Organization of TD data analysis Two parallel techniques: 1.Gabor wavelet fitting for phase and group travel times + ray-path inversions 2.Cross-correlation measurement of reference travel times + Born inversions –Two data analysis options: 1.Standard pipeline processing with standard fitting and inversion parameters 2.Interactive processing (Junwei’s IDL widgets) – should be able to import intermediate data from pipeline processing (e.g. travel times for experimental inversions)

20. Page 20LWS Teams Day JSOC Overview Summary HMI will provide key data to study the Sun’s dynamics and magnetism: subsurface flow maps and photospheric vector magnetic fields. The HMI data analysis plan includes a standard pipeline processing and interactive data analysis tools. The analysis pipeline is being developed by the Co-I team, using existing techniques and software. However, to fully utilize the science potential of HMI additional funding is necessary for Co-I’s teams (in particular, for helioseismic imaging of the deep interior/tachocline, and coronal/heliospheric magnetic field analysis and models).
