A NEW APPROACH TO REAL-TIME WATER-VAPOR WIND EXTRACTION

The prototyping and subsequent validation of a new image-resampling te chnique have shown that the geometric stability of presently available satellite-derived meteorological data could be improved without havin g a negative impact on the radiometric quality. Initial results have a lready shown that 10% more wind vectors pass the quality-control tests thanks to the improved geometric stability of the imagery data. Addit ionally, it has been proven that the derived products can be produced in real time, i.e. on a half-hourly basis. This will increase Meteosat 's economic benefits, particularly in areas where real-time informatio n plays an important role, such as the prediction of hurricane develop ment, and forecasting for aviation, road transportation and ship routi ng.
