Version 5.5 Updates
Version 5.5.4
Became metview/new and metview/default at ECMWF on 2019-06-13 (Linuxdesktops, ecgate, lxc, lxop)
At ECMWF:
Bug fixes:
MARS: linked with latest MARS client to avoid unwanted repeated connections to incorrect server. The symptoms were lots of warning messages, and longer-than-usual MARS retrievals (issue only seemed to arise on 2019-06-12)
Version 5.5.3
Became metview/new at ECMWF on 2019-05-10 (Linux desktops, ecgate, lxc, lxop)
At ECMWF:
Bug fixes:
Macro and Python: fixed a bug where the gradient() function returned its output fields in the wrong order if given multi-field fieldset as input
Macro and Python: fixed a bug where the second_derivative() functions returned values that were too large
Plotting: fixed issue where 200u and 200v were not recognised as wind components for plotting
Plotting: fixed issue where antialiasing was not activated by default for new users
Geopoints Examiner: fixed issue where the values were shown as UNKNOWN
Contouring Editor: fixed issue where keyboard navigation did not work in the style and palette selections
Version 5.5.2
Became metview/new at ECMWF on 2019-04-11 (Linux desktops, ecgate, lxc, lxop)
At ECMWF:
Bug fixes:
Fixed a bug where contouring of a global Gaussian grid encoded in GRIB 1 produced isolines and shading positioned one grid point down from where they should be. This bug was introduced in Metview 5.3.0 (Magics 3.3.1).
Version 5.5.1
Externally released 2019-02-26
Became metview/new at ECMWF on 2019-02-26** (Linux desktops, ecgate, lxc, lxop)
At ECMWF:
Bug fixes:
Fixed issue when retrieving U/V wind components from MARS (issue introduced in Metview 5.5.0)
Version 5.5.0
Externally released 2019-02-15
Became metview/default and metview/new at ECMWF on 2019-02-15** (Linux desktops, ecgate, lxc, lxop)
At ECMWF:
Highlights:
- Macro and Python: a new set of functions based on the
horizontal derivatives of regular lat-lon fieldsets have been added. This is the complete list of the new methods: first_derivative_x(), first_derivative_y(), second_derivative_x(), second_derivative_y(), gradient(), geostrophic_wind_pl(), divergence(), laplacian(), vorticity(). For details please check the fieldset documentation or see the new Gallery example to compute and plot humidity advection here.
Macro and Python: a new set of functions for thermodynamic computations have been added
Macro and Python: new function thermo_parcel_path(), to compute and plot a parcel path in a thermodynamic diagram - please see a Gallery example here and for more details check the documentation
Macro and Python: new function bearing(), to compute the bearing between a point and all points in a GRIB field
Macro and Python: new function edit(), to bring up an interactive editor on the given data or file
Macro and Python: the gfind() function now puts date, time and level into its resulting geopoints variable
Macro Editor: apply the chosen colour theme to the output area
Tephigram: fixed issue when using non-ECMWF BUFR data
Thermo View: new parameter - SUBPAGE_CLIPPING = ON/OFF
Cross Section: fixed issue when plotting a cross section through wind fields
Geopoints:
introduced a new format of geopoints file, which can contain an arbitrary number of named value columns - see Geopoints for more information
geopoints columns can now be extracted and assigned to using direct indexing, e.g. gpt[‘value’] = gpt[‘value’] - 273.15
much more efficient way of creating a complete geopoints variable from scratch using the new form of the create_geo() function
new functions, columns() and value_columns() to return a list of column names
the filter() function can now filter geopoints using a vector as the filter criteria, e.g. new = filter(gpts, gpts[‘precip’] > 5)
improved the display of values in the Geopoints Examiner
Observation Filter and Bufr Picker: added a new mode where multiple parameters can be extracted into the new multi-column geopoints format, essentially meaning that several queries may be made in one go for greater efficiency
Observation Filter: fixed issue when decoding string values from descriptors
Odb Visualiser: added new parameter: FAIL_ON_EMPTY_OUTPUT = YES/NO
EcCharts: new layers added to the ECCHARTS icon: windgust, tmin, tmax, interval-based precipitation layers, precipitation rate layers, model climate layers
EcCharts: improved layer description to include some MARS retrieval information
Stations: updated WMO station list
NetCDF Examiner: fixed issue where the description of ncbyte variables was incorrect
ODB data probe: the ODB data probe in the Display Window now has a new mode, available via the
icon, to only show the values belonging to the point selected by the probe. It was added for the easier inspection of multiple satellite channels available for the same pixel etc.
General: improved error message handling between modules
Interpolation: the Metview source tarball now includes a new internal GRIB interpolation package (see Version 5.4 Updates for more details); if linked additionally with libemos, both packages can also be used for comparison.
Installation: fixed some issues when running on Max OS X
