 * MDI temporal extrapolation scheme does not work at the beginning stage of HMI as we don't yet have past observations. Need to cross calibrate before start using MDI data as initial guess or develop new method.  * MDI temporal extrapolation scheme does not apply as no HMI polar observations are available at the beginning of the mission. Need cross calibration for the possible use of MDI polar data for estimation or perhaps develop a new method.

HMI Pipeline Module - PolarFieldExtrapolation

Extrapolate polar field from past observation and/or low latitude data to fill in the missing data at the polar region of a synoptic map. The output is a complete synoptic map.

Module Inputs
  • Synoptic maps with possible missing data at poles.

Module Outputs
  • Synoptic maps with extrapolated polar field.

Cadence
  • Monthly

Archive
  • Yes

Options
  • Indicate if there are any options when running the code

Overall Status of Module
  • 20%

Status of Code
  • A temporal extrapolation code exists in IDL.

Status of DRMS module
  • Indicate status of DRMS module version of module

Issues needing resolution
  • MDI temporal extrapolation scheme does not apply as no HMI polar observations are available at the beginning of the mission. Need cross calibration for the possible use of MDI polar data for estimation or perhaps develop a new method.
