What is the Helioseismic and Magnetic Imager (HMI)?
HMI is an instrument designed to study oscillations and the magnetic
field at the solar surface, or photosphere. HMI is one of three instruments
on the Solar Dynamics Observatory; together, the suite of instruments
observes the Sun nearly continuously and takes a terabyte of data
a day. HMI observes the full solar disk at 6173 Å with a resolution
of 1 arcsecond. HMI is a successor to the
Michelson
Doppler Imager
on the Solar and Heliospheric Observatory.
What data products are available?
HMI provides four main types of data: dopplergrams (maps of solar surface
velocity), continuum filtergrams (broad-wavelength photographs of the
solar photosphere), and both line-of-sight and vector magnetograms (maps
of the photospheric magnetic field). For more details (such as cadence,
precision, accuracy, and dynamic range) of each data type,
see the left sidebar on the JSOC page.
Where can I get HMI data?
The source of HMI data is the
SDO HMI and AIA Joint Science Operations Center (JSOC)
