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
