Cloud motion estimationCloud motion estimation

– useful as the source data for Numerical Weather Prediction models

– temporary interpolation/extrapolation of image sequences for now casting

– based on adapted optical flow techniques

Budapest 2006

Fractal features extraction

– Based on modeling of Meteosat images by Generalized Brownian Motion processes

– Useful for detecting turbulent areas

Current stateCurrent state

• At the moment Grid middleware is being deployed on SKITs frontend node.

• SKITs are using proprietary local scheduler

• An adapter between Globus GRAM and scheduler should be developed
