    • supported joining of GPhys objects, and GPhys::IO.open is changed to use it, allowing unification of files of any kinds suppored by GPhys.
    • Suppoted unification by non-existent dimensions (e.g., to make time sequence from snapshots).
    • Supported non-monotonic division along axes, such as the latitudinal division of ISPACK with MPI (e.g., file2, file1, file0, file1, file2).
  • Enhanced and improved graphics: new options in GGraph methods and gpview; improved calendar-based axes (to cover many years);
  • Enhanced and improved analysis methods
  • Improved dRuby support

• Click here for older "What's new"s

• Feb 27 2012 gphys-1.2.2 released. Bug fixes and minor improvement.

• Feb 23 2012 gphys-1.2.1 released. -- The only difference from gphys-1.2.0 is that the file install.rb (installer of gp-commands) was re-introduced in the package. No difference in the source codes. (1.2.0 had a problem that install.rb has been eliminated mistakenly.)

• Feb 20 2012 gphys-1.2.0 released.
  • GGraph / DCLExt (Graphics):
    • Supported vector drawing over map projections
    • Separated DCLExt from ggraph.rb into dclext.rb

    • enhnanced histogram (lib/numru/ganalysis/histogram.rb) (NOTE: histogram will be moved into ggraph in future)
    • Planet: added some methods regarding diferentiation on the sphere.
    • Met: added new methods such as z2geostrophic_wind, frontogenesis_func
  • File IO:
    • Supported GRIB2 (available if rb-GRIB is installed) -- But the current version (0.2.0) of rb-GRIB is not recommended. Please wait for a future revision.
    • Improvement in GrADS data handling
  • gp cpmmands:
    • added options (--eddy, --tonf) to gpview, gpvect

• Jul 2 2009 (gphys-0.7.0)
  • supported file formats HDF-EOS5 (swath and grid) and Gtool3

• May 21 2004 (gphys-0.3.2) supports GrADS file writing, though not complete -- so far, you have edit the control file afterwards by hand. Debugs. Minor enhancement of GGRaph.

• Mar 21 2004 (gphys-0.3.1) mostly debugs (and introduction of GPhys::IO)

• Mar 2 2004 (gphys-0.3.0) A major update:
  • GPhys (VArray) now supports units (incl. proper handling upon binary operations etc.).

  • Improved NetCDF convntion handling.
  • And many other minor improvement and debugs

• Jan 29 2004 (gphys-0.2.3) Functionarity enhanced:
  • GPhys#cut spports multiple position specification by Array/NArray

  • And other minor enhancement and many debugs.

• Nov 7 2003 (gphys-0.2.2) Now you can handle GrADS files only by 'require "numru/gphys"'. You can also install the new command grads2nc.rb if you like (by % cd bin; ruby install.rb).

• Sep 18, 2003. The GrADS data format is covered! That's is, GPhys enables you to handle GrADS and NetCDF data in the same way.
  (limitation: Current GrADS support is read only.)
