Synoptic data sets helioseismology

Synoptic Data Sets - Helioseismology

  • Synoptic maps of mass flows and sound-speed perturbations in the upper convection zone for each Carrington rotation with a 2-degree resolution, from averages of full disk time-distance maps;

  • Synoptic maps of horizontal flows in the upper convection zone for each Carrington rotation with a 5-degree resolution from ring-diagram analyses;

  • Higher-resolution maps zoomed on particular active regions, sunspots and other targets, obtained with 4-8-hour resolution for up to 10-day transits;

  • Deep-focus maps covering the whole convection zone depth, 0-200 Mm, with 10-15 degree resolution;

  • Farside images of travel-time perturbations associated with large active regions every 12 hours.

Synoptic Data Sets

  • The traditional line-of-sight component of the magnetic flux is produced as a co-product with the Doppler velocity. Products include synoptic charts updated daily at low, medium, and high resolution. Charts will be constructed at 15 degree offsets from central meridian and adjusted for differential rotation. Synoptic frames available on demand.

  • Synoptic products computed for the coronal and heliospheric field will also be produced, archived, and distributed.

  • HMI will produce several standard data series of the vector magnetic field. A simple ‘magnetograph mode’ analysis will be computed continuously in real time for large scale coronal modeling and other space weather applications. HMI will provide tracked and full-disk vector magnetic field, filling factor, and thermodynamic parameters of photospheric plasma within reasonable errors.

  • Observations of the continuum intensity near the HMI spectral line will give a very useful measure of spot, faculae area and other sources of irradiance.
