- Externally released on 2022-01-19
- Became metview/new at ECMWF on 2022-01-19 (Linux desktops, ecgate, lxc, lxop)
- At ECMWF:
Fixes:
- Fixed issue where passing data from Macro or Python to a separate Metview module could result in that data being kept permanently in memory - observed with Geopoints data
- Fixed issue where clearing a Geopoints variable did not release all its memory
- Fixed issue in the :ref:`geo_to_grib <geo_to_grib_icon>` module where it did not properly ignore missing input values when run in the 'nearest' modes
- Fixed issue in the new :ref:`weather symbol editor <weather_symbols>` where uPlot crashed if a line was added outside of the map area
- Fixed issue in the new :ref:`weather symbol editor <weather_symbols>` where interactive resizing of a line's arrowheads did not take effect until the line was moved

- At ECMWF:
Interactive plot annotations:
Major new feature in the interactive plotting window
Annotation layer with:
- Shapes, lines, markers, text etc.
- Surface analysis (fronts, ridge, ITCZ etc)
- All the WMO Symbols
Accessible through the 'Symbols' tab on the sidebar
See :ref:`How to use the Weather Symbol Editor in Metview <weather_symbols>` for more information on this new feature!
EFAS grids:
with the latest support libraries (ecCodes, Magics, Mir), Metview now supports GRIB files encoded on a lambert azimuthal grid on an oblate spheroid Earth
supported functionality: regridding, plotting, Cursor Data, conversion to geopoints
STVL access:
new module :func:`stvl` to retrieve data from the STVL on internal ECMWF machines (workstations, lxc, lxop)
Plotting:
changes in Magics to improve vertical axis labelling and titles
small adjustment to Single Column Model plots that have two vertical axes in order to accommodate the better-positioned axis title
improved the highlighting of the currently active scene so that it shows a border rather than a filled rectangle, which could obscure the contents:
there is now a way to revert to sending plots to the interactive window: setoutput("screen")
new :ref:`parameters <mcont_icon>` to further control the positioning of grid value plotting:
- contour_grid_value_position
- contour_grid_value_justification,
- contour_grid_value_vertical_align
fixed issue where the Zoom stack was not rendered correctly
requires Magics 4.10.0
Macro/Python:
new function: :func:`solar_zenith_angle`
new function to compute the :func:`speed` from U and V fieldsets:
spd = speed(u, v)
new function: :func:`relative_humidity_from_specific_humidity`
new function: :func:`specific_humidity_from_relative_humidity`
the :func:`grib_get` function now allows to extract GRIB keys in their native type:
a = grib_get(fs, ['level:n', 'centre:n'])
function :func:`saturation_mixing_ratio` now works with fieldsets
improved execution speed of :func:`ml_to_hl`
add option to :func:`ml_to_hl` to specify input data values on the surface
functions :func:`relative_humidity_from_dewpoint` and :func:`dewpoint_from_relative_humidity` now return their results as percentages rather than values in the range [0,1]
fixed crash in :func:`ml_to_hl` when target level is outside input z range
allow :func:`mvl_geopotential_on_ml` to use a subset of levels in arbitrary order, reducing the amount of input data required and therefore the processing requirements
fixed issue where the wind :func:`direction` function accumulated memory
Main user interface:
new user interface themes:
light: similar to previous styling, with some changes for a cleaner look
dark: suitable for 'dark' modes
go to Tools | Preferences to change the setting, or start Metview with -light or -dark command-line switches
improved helper for list parameters in icon editors; short names are now shown, and there is a filter:
fixed issue where the 'stop' button in the Code Editor did not actually terminate a Python process that was started from the editor
fixed issue where an icon sent via the mail tool did not appear as attachment in e-mail clients
fixed a crash when sending icons via the mail tool
Data examiners:
the Geopoints examiner now displays the metadata from the geopoints file:
the GRIB examiner now has a tab to show which tables were used to decode the current message
fixed issue in the BUFR examiner where it crashed when the locations tab was selected on an ill-formed message
Regridding:
- Regridding via either :func:`regrid` or :func:`read` now supports space_view GRIB files as input
- fixed an issue in the :ref:`Regrid <regrid_icon>` module where it crashed if a string is supplied to the Template Data parameter
Other:
- improved filter speed for compressed subsets of BUFR data
- updated the list of WMO stations as used by the :ref:`Stations <stations_icon>` module
- new environment variable: set METVIEW_MARS_HOME to point to the location of non-default MARS config files
- fixed a crash in the WMSClient editor when closing the log panel
- fixed an issue where the Metview bundle did not work on macOS after being installed and configured without an install prefix
