Environmental Disaster Prediction

The implementation and deployment of Grid-enabled services at CMA and ECMWF allows researchers worldwide to discover and retrieve data from the TIGGE databases as well as the provision of simple analysis services, such as statistical computations, to be performed at the data location.


Objectives of the BRIDGE Meteo Application are:


  • to provide a distributed access to TIGGE data
  • distributed processing on distributed data, across the two GRID middleware (GRIA, GOS)
  • Each site hosts only part of the data, and each site offers basic operations on the data (e.g. computing an average)


Strategy: minimize data transfers


  • Run operations at data location
  • Decompose operations in simpler ones
  • Most of the time intermediate results are much smaller

 Deployment of the Meteo prototype 


TIGGE (= THORPEX Interactive Grand Global Ensemble) has been developed within THORPEX. The Observing System Research and Predictability Experiment (THORPEX) has been initiated by the World Meteorological Organisation (WMO) as an internatioal research programme on weather aimed at improving the accuracy of one-day to two-week high-impact weather forecasts, and at developing prediction capabilities at longer lead-times, supported by soundest scientific basis.
