Export Version 4.3.11

External release 2013-09-17

Version 4.3.11-export became available. See the Releases page for download.

User Version 4.3.11

Upgrade 2013-09-17 (Linux desktops, lxab cluster, ecgate)

  • Version 4.3.11 became User Version (command metview4) at ECMWF

Test Version 4.3.11

Introduced 2013-07-08 (Linux desktops, lxab cluster, ecgate)

  • Installed as metview4_new

     

  • Macro: added a vector function to return a vector of sorted indices from a vector:

vector sort_indices(vector)
vector sort_indices(vector, string)
Sorts a vector and returns the sorted indices. The default behaviour is to sort in ascending order unless an alternative comparison function is provided. A second argument consisting of a string can be given: '<' for ascending, '>' for descending order.

  • FLEXTRA: Metview's FLEXTRA modules can now run with 137-level model level data
  • ODB: built with ODB_API version 0.9.31
  • GRIB: built with GRIB_API 1.11.0
  • MARS: rebuilt with the latest MARS client code
  • Magics: rebuilt with latest Magics 2.18.16 (includes an improvement in the legend for marker shading)

Export Version 4.3.10

External release 2013-05-28

  • Version 4.3.10-export became available. See the Releases page for download. Anyone using version 4.3.8 should immediately upgrade to 4.3.10.

Test Version 4.3.10

Introduced 2013-05-28 (Linux desktops, lxab cluster, ecgate)

  • Installed as metview4_new

  • Macro: fixed issue where passing a relative path to a data file was not correctly interpreted by the module which received it
  • Macro: function tolist() now accepts a list as an input type; in this case it simply returns a copy of the input list. This function is normally used for converting a vector into a list, but it is now safe to pass it a list.
  • Macro Editor: fixed issue where dropping a Table Visualiser icon into the Macro Editor did not produce exactly the correct code
  • UI: Macro icons are now allowed as input into icon editors which accept data (GRIB, BUFR, GEOPOINTS and NETCDF) icons. Examples would be a Cross Section Data icon or a Simple Formula icon.

User Version 4.3.9

Upgrade 2013-05-21 (Linux desktops, lxab cluster, ecgate)

Export Version 4.3.4

External release 2012-10-29

  • Version 4.3.4-export became available. See the Releases page for download.
  • NOTE: Requires Magics++ version 2.18.1 - see the Magics Releases page.

Test Version 4.3.4

Introduced 2012-10-29 (Linux desktops, lxab cluster, ecgate)

  • Installed as metview4_new

  • Built with Magics 2.18.1 See the Magics Change History.

  • Fixed issue where ObsFilter was not working with Level=Occurrence
  • Fixed issue where Cross Section was producing an empty plot when transect line was of constant longitude
  • Fixed issue where Cross Section was producing an empty plot when given data in model levels with LNSP
  • Fixed issue where the Data Examiners would remain active after their Metview session had been closed, occasionally consuming large amounts of CPU time
  • Fixed issue where the Display Window crashed if the metadata sidebar was open when plotting grid values
  • Reorganised the sidebar's content in the Display Window. The Layers tab now only contains the layer list and a new tab called Data was added for the layer data. By selecting the Data tab users are able to see metadata and data values associated with the selected layer.
  • New feature: added the ability to shade the area between two curves with the Input Visualiser (Input Plot Type = XY Area)

  • New feature: ODB data probe. From the Display Window, select the Data tab, then click the Values button to show the data values for the current plot area. An icon at the bottom-left of this tab activates the data probe, which is a movable on-screen probe; as it is positioned over a data point, the corresponding row in the data table is highlighted. Conversely, if a row in the data table is highlighted, the data probe is automatically positioned over the corresponding point on the map.

 

  • New feature: enabled ODB Visualiser to save additional columns to the resulting ODB. A parameter called ODB_METADATA_VARIABLES was added to the ODB Visualiser. The columns specified here will be added to the ODB Visualiser's output on top of the lat/lon/value etc. columns. These extra columns can then be examined in the Display Window's Data/Values tab.

  • New feature: added show/hide columns option to the Data tab of the ODB Examiner
  • New feature: added expression support for column variables in the ODB Visualiser. Previously the column variables in ODB Viusaliser could strictly take column names. Now arbitrary ODB expressions/functions can be used for them, e..g. by setting ODB_VALUE_VARIABLE to an_depar-fg_depar will result in plotting of the difference between the analysis and first guess departures.
  • Alphabetically sorted columns in the Data tab of the ODB Examiner
  • Plotting speed has been improved in the interactive Display Window

  • New environment variable: METVIEW_EXTRA_GRIB_DEFINITION_PATH. Metview now understands a new environment variable which users can use to specify a directory where custom GRIB_API definition files are stored. METVIEW_EXTRA_GRIB_DEFINITION_PATH should be set before starting Metview.

  • New Macro function: grib_get() for the efficient retrieval of multiple GRIB keys from a fieldset. Description:

list grib_get(fieldset, list)
list grib_get(fieldset, list, string)

For the efficient retreival of multiple GRIB keys from a fieldset. The keys are provided as a list for the second argument; by default they will be retreived as strings, but their type can be specified by adding a modifier to their names, following the convention used by grib_ls where the key name is followed by a colon and then one or two characters which specify the type (s=string, l=long, d=double, la=long array, da=double array). For example, the key 'centre' can be retreived as a string with 'centre' or 'centre:s', or as a number with 'centre:l'. The result is always a list of lists; by default, or if the optional third argument is 'field', the result will be grouped by field, containing one list per field, each of these lists containing one element per key; if the optional third parameter is 'key', the result will be grouped by key, containing one list per key, each of these lists containing one element per field. Example - the following lines of Macro code on a particular 6-field fieldset:

print(grib_get(data, ['editionNumber', 'centre',   'level', 'step'], 'field'))
print(grib_get(data, ['editionNumber', 'centre:l', 'level', 'step'], 'key'))

produces this output:

[[1,ecmf,1000,0],[1,ecmf,500,0],[1,ecmf,100,0],[1,ecmf,1000,48],[1,ecmf,500,48],[1,ecmf,100,48]]
[[1,1,1,1,1,1],[98,98,98,98,98,98],[1000,500,100,1000,500,100],[0,0,0,48,48,48]]

User Version 4.3.3

Upgrade 2012-09-18 (Linux desktops, lxab cluster, ecgate)

  • Version 4.3.3 became User Version (command metview4) at ECMWF

Test Version 4.3.3

Introduced 2012-09-13 (Linux desktops, lxab cluster, ecgate)

  • Installed as metview4_new

  • Built with Magics 2.16.2 See the Magics Latest News.

  • The Macro function read() can now read a Macro file, returning a list of strings, one per line of text. This is the same behaviour as already existed for reading general ASCII text files.
  • Improved the Display Window's Cursor Data for very small values (if the values are very small, it switches to scientific notation).
  • Installation: fixed an issue where a custom startup script name was causing the build to fail in the scripts directory

  • NOTE: this is the version that will become the user version at ECMWF on Tuesday 18th September 2012, 09:00 GMT.

Export Version 4.3.2

External release 2012-08-14

  • Version 4.3.2-export became available. See the Releases page for download.
  • Built with latest Mars client code
  • Installation: issue with detecting the Magics library resolved
  • Installation: issue with building Qt modules on certain systems (e.g. Ubuntu 12.04) resolved
  • NOTE: Requires Magics++ version 2.16.1 in order to build the Qt/Magics-based plotting module - see the Magics Releases page

Export Version 4.3.1

External release 2012-08-06

  • Version 4.3.1-export became available. See the Releases page for download.

Test Version 4.3.1

Introduced 2012-08-06 (Linux desktops, lxab cluster, ecgate)

  • Installed as metview4_new

  • Built with Magics 2.15.8

  • New Macro function sort(vector, string) returns a sorted version of the given vector. If no second argument is given, the result will be sorted in ascending order; otherwise, a second argument consisting of a string can be given: '<' for ascending, '>' for descending order. See Vector Functions.

  • Macro: fixed issue when reading floating-point netCDF attributes - there had been occasions where very large numbers had some digits cropped . This only affected attributes which were floating point, and not actual data values.

  • Macro Editor: 'find/replace' actions now wrap around

Test Version 4.3.0

Introduced 2012-07-16 (Linux desktops, lxab cluster, ecgate)

  • Installed as metview4_new
  • Built with Magics 2.15.7
  • New module: Grib Vectors
    - similar to Metview 3's Vectors module. The purpose is to tell Metview to plot given pairs of fields as vectors. Also allows for the colouring of the arrows by a third field.
  • Improved automatic recognition of vector fields, including wave fields
  • New module: Opera Radar Filter
    - new module for the purpose of reading OPERA radar BUFR messages and converting the data to geopoints format.
  • ObsFilter module: extended level filter to work with arbitrary coordinate descriptors.
    The level filter in ObsFilter has so far only allowed surface or pressure level/layer selection. Now two new options were added to the level filter so that it could work for any kind of coordinate descriptors (e.g. height, satellite channel etc). These two new
    options are follows:
    - Descriptor Value: If Level is set to Descriptor Value then ObsFilter performs level filtering according to the descriptor specified in Level Descriptor. The level value is taken from parameter First Level.
    - Descriptor Range: If Level is set to Descriptor Range then ObsFilter works similarly but selects the first available level in the specified range. The level range is taken form parameters First Level and Second Level.
  • New macro function: filter(vector, vector)
    - takes two vectors, and returns a new vector containing only the values of the first vector where the second vector's values are non-zero and non-missing. See Vector Functions.
  • Plotting: added parameter LEGEND_TITLE_ORIENTATION to the Legend icon
    - Horizontal/Vertical
  • Macro: added optional 'resize' parameter to set_values(fieldset, vector)
    - if the user wants to create a new fieldset from a template, they may wish to change the number of values. The default behaviour is to produce an error if the input fieldset and vector have different numbers of values. If, however, a third parameter (set to the string 'resize') is passed to the function, the resulting fieldset will instead be resized to have the same number of values as the input vector.
  • Geo To Grib module: fixed issue in determining the size of the resulting grid. Also more checks to ensure the consistency of the requested grid (e.g. if grid resuolution matches the size of the domain)
  • Fix in stdev(fieldset) macro function (inherited from Mars code)
  • Macro editor: improved visual display of whitespace characters
    - available from the Settings | Tabs menu
  • Fix in the setting of a plot area in Lambert projection
  • Updated mvl_ml2hPa() to properly encode levels < 1 hPa
  • Removed code for handling computations with GRIB fields stored in polar
    stereographic grids. This does not affect the plotting of data onto a polar stereographic map.
  • Smaller fixes and improvements
