Experiments with Atmospheric Motion Vectors at Ecmwf
Two new developments in extracting wind information by tracking of clouds or water vapour features are increasing the spatial coverage and providing quality estimates for individual observations. The transition from low density to high density wind observations of both GOES satellites led to first experiences with increased spatial coverage in NWP centres. The relative impact of low density and...
متن کاملSESSION I CURRENT SYSTEMS TO DERIVE ATMOSPHERIC MOTION VECTORS (AMVs)
Session I contained seven presentations, which described the status of systems, used in the production of Atmospheric Motion Vectors (AMVs). Each of the major production centres described present and future plans. A common thread in many of the presentations was the emerging production of high-density winds. The use of high density winds and improvements in quality control procedures portend a ...
متن کاملImproved Quality Estimates of Atmospheric Motion Vectors Utilising the Eumetsat Quality Indicators and the Uw/cimss Auto-editor
The development of reliable Automatic Quality Control (AQC) schemes has played a key role in the development of the new high density and high frequency Atmospheric Motion Vector (AMV) products at UW/CIMSS and EUMETSAT. Despite the fact that the AQC schemes in the two organisations differ significantly it has previously been shown that both schemes are capable of assigning reliability factors to...
متن کاملRecent Research in the Automated Quality Control of Cloud Motion Vectors at Cimss/nesdis
Wind estimates derived via remote sensing of satellites are not direct measurements, and therefore require rigorous quality control. Historically this has been provided by human intervention, but with increasing sources and numbers of wind estimates, objective methods for quality control are both attractive and necessary. This presentation addresses the current methods applied operationally at ...
متن کاملMotion compensation of motion vectors
Motion compensation of image data has long been used for video compression. “Meta-motion” compensation, or motion compensation of motion vectors is presented as a new approach to data compression useful in very low bitrate (VLB) applications. Whereas present motion coding simply takes advantage of temporal redundancies among images, this new, computationally simple approach takes advantageof te...
