Export Version 4.5.7

External release 2015-10-16

Version 4.5.7-export became available. See the Releases page for download.

Test Version 4.5.7

Introduced 2015-10-07 (Linux desktops, lxab and lxc clusters, ecgb)

  • Tephigrams: added Thermo Grid and Thermo Plotting icons for controlling the plotting of the background and curves of a tephigram. Plotting of wind arrows is still controlled by the Wind Plotting icon. Full drag and drop support is now implemented between the various "Thermo" icons.
  • Cross Section: added support for plotting cross sections of wind vectors. Users are now able to customise the scaling of the vertical wind if desired.
  • Cross Section: added new parameter to the Cross Section View and Cross Section Data icons: Horizontal Point Mode, which now allows the points along the transect line to be computed either via interpolation of the surrounding grid points (the default behaviour) or using the nearest grid point (the new option).
  • Cross Section: revised method to determine which pressure levels to interpolate onto when converting from model level data. The new scheme ensures that the plot continues down to the bottom even in cases where there is extreme orography.
  • Cross Section: added parameters to allow a user-defined list of pressure levels to interpolate onto when converting from model level data. See Cross Section Data and Cross Section View.
  • Plotting: parameter Symbol Text Blanking in the Symbol Plotting icon is now available in the table modes
  • Plotting: new Coastlines parameters available: Map Label FontMap Label Font Style and Map Label Blanking
  • Display Window: the Cursor Data can now be significantly faster (e.g. 100x) with some large fields. Note that this requires Magics 2.25.2.
  • Display Window: some options in the Export dialogue from the plot window were erroneously displayed as plain strings instead of a fixed list of possible values.
  • User Interface: now closes properly during a system shutdown
  • GRIB: ensured that Metview now works with negative forecast steps (when built with GRIB_API 1.15.0)
  • GRIB: Metview now uses higher-level GRIB_API keys for checking flags relating to grid interpretation. This does not fix any known bugs, but should be safer.
  • Build: installers can now specify a different path to install Metview's executables by supplying to CMake a path relative to the base install directory, for example:
    • -DMETVIEW_INSTALL_EXE_BIN_DIR=lib/metview/bin
  • Build: fixed issue when building Metview's fortran modules with Intel compilers.
  • Build: Metview now builds with Qt5. There is an issue with the main menu on Mac OS X which seems to affect other applications; the menu becomes active only after switching context to and then from another application.
  • Build: added the ability to run post-installation tests for added confidence in the installation. From the build directory:
    • cd tests/macros

Test Version 4.5.6

Introduced 2015-06-17 (Linux desktops, lxab and lxc clusters, ecgate)

Export Version 4.5.6

External release 2015-06-16

Version 4.5.6-export became available. See the Releases page for download.

  • Plotting: fixed issue where plotting of small details in PDF and PNG format gave a bad plot because of outline attributes which were too thick
  • Plotting: fixed rare issue where the plotting of a data file which is a symbolic link could fail
  • GRIB: fixed issue where Metview's internal GRIB navigation routines did not correctly compute the coordinates of the points on a GRIB field which is a sub-area of a reduced Gaussian grid. This affects a number of functions and modules, including Grib to Geopoints, Cross Section and the Macro functions nearest_gridpoint() and interpolate().
  • Grib Examiner: fixed issue where the Grib Examiner could crash when switched to Namespace mode
  • Examiners: fixed issue where the data examiner applications (e.g. the Grib Examiner) could crash when closed; this was normally not visible, but could show up on the Mac OS X
  • Stations: the Stations module has been updated to use the latest list of WMO stations
  • User Interface: allow the dropping of Metview 3 (e.g. PCONT) icons into the icon editor of Metview 4 (e.g. MCONT) icons to aid migration
  • Startup: fixed the display of the Metview version when typing "metview -h"

Test Version 4.5.4

Introduced 2015-05-12 (Linux desktops, lxab cluster, ecgb)

  • Legend: added new parameter to the Legend icon - Legend Automatic Position. Can have one of two values: top (default) and right. This allows a legend to be automatically positioned to the right of the plot without the need to manually specify its coordinates
  • Contouring: now, when Contour Shade Technique is set to Grid Shading, all interpolation of the input GRIB field is automatically deactivated without the user having to set additional parameters, true to its original intention (e.g. Contour Method previously had to be set to Linear)
  • Contouring: parameter Contour Reference Level is now available even if Contour Highlight is Off
  • Contouring: allow access to the parameter Contour Internal Reduction Factor to allow fine-grain control over contouring of certain fields
  • Plotting: now the page_frame parameters from view icons are honoured
  • NetCDF: the ncdump panel of the NetCDF Examiner was not working on the new workstations at ECMWF; now it is
  • Reprojection: all the meta-data in the Product section of the input GRIB file is now transferred to the resulting GRIB file
  • Macro: it is now possible to specify that a coastlines definition be plotted on top of the data - just put the coastlines variable at the end of the plot command (or anywhere after the first data variable)
  • Macro: fixed issue where putting a visdef variable at the start of a plot() command could cause a crash
  • Macro: when supplying a relative path when using multiple output graphics file formats, the files will now be generated in relative to where the macro is located
  • Macro: improved printing of error messages from other modules
  • Macro: fixed an issue where the function nearest_gridpoint() could return the wrong point in a particular edge case where the longitude is beyond the last point, e.g. in a 1x1 degree grid, asking for the nearest gridpoint to (0, 359.1) returned the wrong result
  • Stations: a new parameter, Fail on Error was added. If this is set to No, then a macro can trap the condition where it does not find a matching station by checking whether the return result is nil.
  • SCM: fix to allow the running of SCM executables on the classroom machines
  • SCM: fixed occasional crash in SCM profile editor
  • Mac OS X: chosen better default viewers for image formats such as PNG and PostScript
  • Mac OS X: graphics are now crisper due to the choice of a different Qt rendering engine on this platform
