- Support for gfortran added

Tested platforms

- Linux: SuSE 9.1 - IBM: AIX 5.1

- SGI: IRIX 6.5 - HP: HP-UX B.11.00

- Alpha: OSF1 V5.1 - Sun: SunOS 5.7

Magics++ Export version to Member states has been released

The current available export version is 2.0.1

- Released 2007-04-17

The latest internal test version is 2.1.0

Tested platforms

- Linux: SuSE 9.1 / 10.x (32 and 64 bit)

- IBM: AIX 5.3

- Tested compilers: g++, icpc, xlC (gfortran, pgf90, ifort, xlf90)

- We are collecting feedback from Member States which platforms (operating system / distributions + compilers) they use to get a better overview

Magics++ Metgrams

Used to produce

the new 15 day

VarEPS metgram

Thanks to MagML

it is easy to adopt

metgrams to

new requirements

Magics++ - new featuresBoxplots available for users

through easy interface

Maps with more than 360°in Longitude with wrap-around display of data

Different resolutions ofcoastlines

MapGen data files allow users to add own borders and rivers

User logo


Slide 9

Magics++ - MagML

XML based format to describe Magics++ plots

Descriptive, not procedural

No need for (re-)compilation

magml interpreter program processes a MagML file and produces output graphics

Interpreter can be easily called in user code

Description close to Metview’s icon convention

Can be integrated into more complex XML request descriptions


Slide 10

Magics++ - MagML usageMagML is very popular with individual users at ECMWF

Main aim is the large scale automatic production of plots

MagML enables easy use of new features of Magics++ to make it more attractive for producing web output

- Generating meta information to support scripting of web output

- Transparency support in improved drivers

- Layers

- New formats: SVG, GIF, PDF

Used in this way in the Services-On-Demand project at ECMWF

Ideal as backend for web interfaces with constant layout and visual properties but changing data

Support for satellite data

New MagML syntax – taking into account all the feedback we received

Support for observationsExtensions to Metgrams, such as display of

wind direction and climateImprove support for NetCDF (3D data sets)

Metview Principles

First MetviewPrinciple:

“Everything in Metview is an Icon”

Second Metview Principle:

“Every Metview Task is a sequence of actions on icons”

Metview UI – user feedback

Easy to learn and use

Users like small menus

Icon concept reflects meteorological content

Icons and Macro objects are the same – future Macros can be easily prototyped in the GUI

Default behaviour can be easily adjusted, and templates of icons exchanged between Metview users

… still long list of improvements:

- Macro editor needs improving

- More features to process satellite data

- Eventually replace Motif


Slide 21

Metview – developments (1)

There is a continuing routine effort to incorporate new facilities into Metview. These constant improvements include

- New requirements, such as enhancements for BUFR Edition 4

- 'Percentile' application (EPS)

- 'Height' and 'Expand' applications were added into Hovmöller Family

- Satellite Image re-projection application

- EPS-metgram, 15 Days EPS metgram, and Classic Metgram now use Magics++

- Enhanced Macro memory usage

Metview – developments (2)

New features were added into Metview to meet user requirements, including several Metview Macro functions:

- remove_duplicates, var_a, stdev_a, covar_a, corr_a, search, tmpfile, frequencies, integer, unipressure, unithickness

Add macro functions for code timing

New compilers, such as GCC 4 and gfortran, were tested

Routine efforts also include training courses, software maintenance and support for both internal and external Metview users

Metview - releases

The latest internal Metview version is 3.9.3 which is based on Magics 6.12 and Emoslib cycle 000320

Metview 3.9-export, released 2006-11-10, supports the extended VarEPS

Tested platforms

- Linux: SuSE 9.1 - IBM: AIX 5.1 / 5.3

- SGI: IRIX 6.5 - HP: HP-UX B.11.00

- Sun: SunOS 5.7


Slide 27

27

Metview - plans

Tests have been started to use the grib_api within Metview to handle Grib 2 data. This will be part of the next export version

A general purpose Macro library

A new visualisation module to take advantage of all the benefits provided by Magics++

The first prototype using Magics++ aims to execute current operational Metview Macros


Slide 28

28

Magics++Future Benefits for Metview Magics++ and Metview will both use C++

More input and output formats

Improvements in user interactivity, such as legend/text handling

The ability to dynamically toggle certain graphical objects, such as contour labels and maxima/minima

Querying the properties of graphical objects displayed on screen

Generate MagML for service-on-demand (web)
