Description NLFFF extrapolations of AR10978 — analysis volumes

Brief description

The results from a study to discern the dependence on spatial resolution by
the various nonlinear force-free field (NLFFF) extrapolation methods are
described in DeRosa et al. (2015). This dataset contains the analysis
volumes from all 71 NLFFF extrapolations that were analyzed as part of the study. All bin levels for all methods are available, with the exception of
the magnetofrictional solution for bin level 3. For the Grad-Rubin methods,
both the N and P solutions are available. The data and metadata
are stored in the nonproprietary HDF5
format, for which bindings exist in C, C++, Fortran90, IDL, Java, MATLAB,
Python, R, and many other languages.



Filename convention
The filenames below use the following convention:


  • binXX_opti.h5 : analysis volumes for the optimization method for bin level XX
  • binXX_magf.h5 : analysis volumes for the magnetofrictional method for bin level XX
  • binXX_cfit.Y.h5 : analysis volumes for the CFIT code for bin level XX, where Y indicates either the N
    or P solution
  • binXX_femq.Y.h5 : analysis volumes for the FEMQ code for bin level XX, where Y indicates either the N or P solution
  • binXX_xtra.Y.h5 : analysis volumes for the XTRAPOL code for bin level XX, where Y indicates either the N or P solution



Data and metadata contained in each file

For each case, the data file contains the following arrays:


  • NLF: four-dimensional array containing Bx,
    By, and Bz as a function
    of x, y, and z

  • XINDEX: index of x dimension, in Mm

  • YINDEX: index of y dimension, in Mm

  • ZINDEX: index of z dimension, in Mm
