IBL’s cooperation with WAFC trialsIBL’s cooperation with WAFC trials
• We committed to:– Evaluation of UK Met Office experimental
fields.– SADIS GRIB2 dissemination trial.– “Long Haul” charts.– Monitoring of SADIS reception quality.
• This presentation:– Experiments with visualisation of the WAFC
experimental fields.– Some experience and feedback gained.

Single parameter visualisations don’t provide any real added value however they are easily interpretable.

New Parameters Visualisation New Parameters Visualisation ChallengeChallengeProposed gridded information cannot be resonably presented in geospatial context.Taking also vertical extents into account, there will „too much“ information available in any layered view.

Opposite Opposite Minimalistic ApproachMinimalistic ApproachApplying a business logic in the workstation may create added value product which can be more easily interpreted. However this naturally hides some details but can copes better vertical extent (as the present SIGWX charts).

SIGWX BUFR vsSIGWX BUFR vs.. New gridded products New gridded products (1)(1)
• Technical experience:– Both are WMO proprietary formats.– SIGWX is presently created from higher resolution
NWP grid than whatever is/will be in WAFC distribution.
– New gridded products will require more business logic to be implemented on the workstation.
– SIGWX production automation could allow coexistence of feature objects (BUFR/XML/GML?)
– Missing values are encoded with special values such as 0m CB base height.
– 3h forecast step will allow better interpolation.

• User experience:– “Too much” information and also...– ...SIGWX captured the vertical extent– Missing “key” how to use and interpret the data.
Especially to avoid ambiguous or misleading interpretations.
– Use of cross-section products increases demand for more precise specification of flight route what is not always possible.
– Availability of wider forecasts range and finer step may allow more accurate and wider end-user products than fixed +24h SIGWX.

Synergy of Synergy of features vs. gridsfeatures vs. grids
Feature objects cannot be simply interpolated in time – this would require change in their data model.
