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
