Version 5.9 Updates

Version 5.9.1

  • Externally released on 2020-07-22

  • Became metview/new at ECMWF on 2020-07-22 (Linux desktops, ecgate, lxc, lxop)

  • At ECMWF:

    • Installed 2020-07-22

    • Built with Magics 4.4.1

    • Built with ecCodes 2.18.0

    • Built with ODB_API version 0.19.4

    • Includes version 1.4.2 of the Python interface

BUFR Filtering:

  • fixed issue where geopoints were sometimes generated with a mixture of spaces and tabs; now in these cases, only tabs are used

MARS access:

  • fixed issue where fdb5 was not being directly accessed when Metview is built at ECMWF

Meteogram:

  • fixed issue where the Meteogram module could crash if given a large number of stations (> 20 or so)

Plotting:

  • fixed issue in the Geographical View icon where some of the pre-defined areas in polar stereographic projection were not correctly plotted

ecCharts:

  • the ECCHARTS module is now built by default; previously it was only built if the UI was built

Tests:

  • fixed a geopoints test that was failing with clang compilers

Version 5.9.0

  • Externally released on 2020-06-24

  • Became metview/new at ECMWF on 2020-06-24 (Linux desktops, ecgate, lxc, lxop)

  • At ECMWF:

    • Installed 2020-06-24

    • Built with Magics 4.4.0

    • Built with ecCodes 2.18.0

    • Built with ODB_API version 0.19.4

    • Includes version 1.4.2 of the Python interface

Plotting:

  • support for more grids, with the latest versions of ecCodes (2.18.0) and Magics (4.4.0):

    • Mercator grid supported for processing and plotting, including Cursor Data

    • Lambert Azimuthal Equal Area grid, including on oblate spheroid, supported for plotting

    • Lambert Conformal grid supported for processing and plotting, including Cursor Data

    • Polar Stereographic grid supported for plotting, including Cursor Data

  • Input Visualiser now accepts vectors (Macro langauge) and numpy arrays (Python) for the following parameters: input_x_values, input_y_values, input_x2_values, input_y2_values, input_longitude_values, input_latitude_values, input_values. For arrays with more than 10,000 or so entries, this can provide a speed up of hundreds of times compared to using lists. Example plot using the Binning options of the Input Visualiser:

  • Improved step string in the title of a FLEXPART plot using the flexpart_build_title() function - for example, a step of 90 minutes will now be rendered as “1h 30m” in the title

BUFR:

Fortran:

  • Metview’s two remaining Fortran-based modules, Potential Temperature and Spectra, have now been re-written in C++, meaning that a Fortran environment is no longer required in order to use them. These modules were disabled in Metview’s conda builds in order to avoid the need for Fortran; from this release onwards, they will be available in the conda versions

Macro/Python:

  • function direction() now handles missing values properly - see Fieldset Functions

  • function univertint() now supports pressure levels as input

  • added function filetype() to return the internal Metview type of a given file

  • Macro-based user interfaces can now use the help_script parameter for any input type

macOS:

  • fixed issue seen on macOS where the area selection tool in the Geographical View icon editor could cause a crash

  • fixed issue seen on macOS where using the Cross Section View and related icons multiple times could cause instability
