HMI Pipeline Module - PotentialFeildLocal

Provide local potential field approximation in high resolution from HMI vector field data

Module Inputs

• Local magnetic field map at time and position of interest that will be probably determined by an active region recognition program.

Module Outputs

• 1) Three-dimensional volume data : all 3 components of magnetic field in the volume of interest.
• 2) Plot, visualization
• 2-a) Field-line projected onto the solar surface or viewed from the Earth and other directions.
• 2-b) Map at the base (photosphere) about whether field be open or closed. (?)

Cadence

• Once or a few times per day

Archive

• 3D data will be archive

Options

• Sizes in both horizontal and vertical directions be determined in accordance with those of input data

Overall Status of Module

• 1-a) Iterative solver for Laplace equation : almost done, including OpenMP parallelism
• 1-b) Green function method : almost done, including OpenMP parallelism, 256x256(x256) be finished in 20 min. or shorter.
• 1-c) efficient methods such as Fourier methods : 30 % or less
• 2) Drawer / plotter : 50 %
• 1-a) and 1-b) are being tested in DRMS/JSOC context.

Status of Code

• 90 % in total

Status of DRMS module

• Tested as stand-alone : done
• Run as DRMS or JSOC module: mostly done for iterative method and Green function method

Issues needing resolution

• So far, "patch"-data prepared by hand is used for test.
• Preparation of input data in a atutomated and timely manner remaining
