Version 5.14 Updates
Version 5.14.1
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 geo_to_grib module where it did not properly ignore missing input values when run in the ‘nearest’ modes
Fixed issue in the new weather symbol editor where uPlot crashed if a line was added outside of the map area
Fixed issue in the new weather symbol editor where interactive resizing of a line’s arrowheads did not take effect until the line was moved
Version 5.14.0
Externally released on 2021-12-07
Became metview/new at ECMWF on 2021-12-07 (Linux desktops, ecgate, lxc, lxop)
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 How to use the Weather Symbol Editor in Metview 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
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 parameters 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:
solar_zenith_angle()
new function to compute the
speed()
from U and V fieldsets:spd = speed(u, v)
new function:
relative_humidity_from_specific_humidity()
new function:
specific_humidity_from_relative_humidity()
the
grib_get()
function now allows to extract GRIB keys in their native type:a = grib_get(fs, ['level:n', 'centre:n'])
function
saturation_mixing_ratio()
now works with fieldsetsimproved execution speed of
ml_to_hl()
add option to
ml_to_hl()
to specify input data values on the surfacefunctions
relative_humidity_from_dewpoint()
anddewpoint_from_relative_humidity()
now return their results as percentages rather than values in the range [0,1]fixed crash in
ml_to_hl()
when target level is outside input z rangeallow
mvl_geopotential_on_ml()
to use a subset of levels in arbitrary order, reducing the amount of input data required and therefore the processing requirementsfixed issue where the wind
direction()
function accumulated memory
Main user interface:
new user interface themes:
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
regrid()
orread()
now supports space_view GRIB files as inputfixed an issue in the Regrid 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 Stations 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
