Metview 4.4 introduces new icons for Cross Section Data, Average Data, Vertical Profile Data, Cross Section View, Average View and Vertical Profile View. Their functionality remain largely the same, but the concepts have been cleaned up, with a clearer separation between the responsibilities of the Data icons and the View icons. For example, specifying that the result should be plotted with a logarithmic axis should not be part of the Data icons, but should instead be the sole responsibility of the View icons, as it is a purely visual characteristic. Additionally, some parameters were not generic enough - for example, the Top Pressure parameter can also be used when the data are in model levels, and has therefore now been renamed to Top Level.

 

Migrating from Metview 3 to Metview 4.4

Cross Section Data

  • Existing icons will continue to work, but with the following limitations:

    • Pressure Level Axis will be ignored; Linear will be used. The Cross Section View can be used to change this
    • Top Pressure and Bottom Pressure will be ignored; Metview will generate its result using the whole data range. The Cross Section View can be used to change this
  • To migrate to the new icon:
    • to control the type (linear/log) or the range of the vertical axis, the use the Cross Section View
    • The macro function name has changed from cross_sect() to mcross_sect()

Average Data

  • What is true for Cross Section data is also true for Average Data, except:

    • the Average Section View icon is used to control the visualisation aspects
    • The macro function name has changed from xs_average() to mxs_average()

====================================

 

- XSECTION VIEW

  - Metview 4.4 x Metview 4.3

     - Metview 4.3 icon will not be visible in the UI

     - Metview 4.3 macro command may crash depending on the parameters selected.

       This is because the definition file was updated and it is not backwards compatible and

       the macro command is the same (PRESSURE_AXIS_TYPE)

     - There is a new parameter, VERTICAL_LEVEL_TYPE, which may cause problems to the automatic

       translation, e.g.: dropping a Model level data without LNSP.

     - how to migrate:

         - The following parameters need to be changed:

            - replace PRESSURE parameters to LEVEL

            - Pressure level axis to Vertical scaling

 

   - Metview 4.4 x Metview 3

      - Metview 3 icons should be translated except for the case when user supply data in model

        level without lnsp.

      - how to migrate:

         - The following parameters need to be changed:

            - replace PRESSURE parameters to LEVEL

            - Pressure level axis to Vertical scaling

            - replace macro function

 

 

  

- AVERAGE VIEW

   - same as xsv

 

 

- VERTICAL PROFILE VIEW

   - Metview 4.4 x Metview 4.3

     - Metview 4.3 icon will not be visible in the UI

     - Metview 4.3 macro command may crash depending on the parameters selected.

       This is because the definition file was updated and it is not backwards compatible and

       the macro command is the same (PRESSURE_AXIS)

     - There is a new parameter, VERTICAL_LEVEL_TYPE, which may cause problems to the automatic

       translation, e.g.: dropping a Model level data without LNSP.

     - how to migrate:

         - The following parameters need to be changed:

            - replace PRESSURE parameters to LEVEL

            - Pressure level axis to Vertical scaling

 

   - Metview 4.4 x Metview 3

      - new parameters VERTICAL_SCALING and X_MIN_MAX

      - how to migrate:

        - The following parameters need to be changed:

          - replace PRESSURE parameters to LEVEL

          - PRESSURE_AXIS to LEVEL_AXIS parameter

          - replace macro function

 

- VERTICAL PROFILE DATA

   - Metview 4.4 x Metview 3

      - PRESSURE_LEVEL_AXIS parameter will be ignored -> LINEAR will be used

      - Metview 3 PRESSURE parameters will be ignored. Metview 4 will use the min/max values from

        the data

      - Metview 4 has a new parameter VERTICAL LEVEL TYPE, which may cause problems to the

        automatic translation, e.g.: dropping a Model level data without LNSP.

      - how to migrate:

          - for LOG axis, use the vpv

          - replace macro function

          - may need to specify parameter VERTICAL_LEVEL_TYPE
