New WAFC Gridded Products = New Visualisation Opportunities Jozef Matula WAFS Workshop on the Use and Visualisation of Gridded SIGWX Forecasts, Paris, 14 -15. 09. 2009

IBL’s cooperation with WAFC trials • We committed to: – Evaluation of UK Met Office experimental fields. – SADIS GRIB 2 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.

New Parameters Visualisation Challenge Proposed 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. WAFS Workshop on the Use and Visualisation of Gridded SIGWX Forecasts, Paris, 14 -15. 09. 2009

Opposite Minimalistic Approach WAFS Workshop on the Use and Visualisation of Gridded SIGWX Forecasts, Paris, 14 -15. 09. 2009 Applying 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).

CONCLUSIONS & FEEDBACK WAFS Workshop on the Use and Visualisation of Gridded SIGWX Forecasts, Paris, 14 -15. 09. 2009

SIGWX BUFR vs. New gridded products (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 0 m CB base height. – 3 h forecast step will allow better interpolation. WAFS Workshop on the Use and Visualisation of Gridded SIGWX Forecasts, Paris, 14 -15. 09. 2009

SIGWX BUFR vs. New gridded products (2) • 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 +24 h SIGWX. WAFS Workshop on the Use and Visualisation of Gridded SIGWX Forecasts, Paris, 14 -15. 09. 2009

Synergy of features vs. grids Feature objects cannot be simply interpolated in time – this would require change in their data model. WAFS Workshop on the Use and Visualisation of Gridded SIGWX Forecasts, Paris, 14 -15. 09. 2009
