Magics++ - Grib 2
Used in
monitoring
TIGGE’s Grib 2
data using
MagML

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 features
 Boxplots available for users
through easy interface
 Maps with more than 360°
in Longitude with wraparound display of data
 Different resolutions of
coastlines
 MapGen data files allow
users to add own borders and rivers
 User logo

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

Magics++ - MagML usage
 MagML 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

Magics++ - plans
 Support for satellite data
 New MagML syntax – taking into account all the
feedback we received
 Support for observations
 Extensions to Metgrams, such as display of
wind direction and climate
 Improve support for NetCDF (3D data sets)

Metview Principles
 First Metview
Principle:
“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

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
