متن کاملOn the assimilation of ice velocity and concentration data into large-scale sea ice models
Data assimilation into sea ice models designed for climate studies has started about 15 years ago. In most of the studies conducted so far, it is assumed that the improvement brought by the assimilation is straightforward. However, some studies suggest this might not be true. In order to elucidate this question and to find an appropriate way to further assimilate sea ice concentration and veloc...
متن کاملPotential of RADARSAT-2 data for operational sea ice monitoring
Synthetic aperture radar (SAR) data from RADARSAT-1 are an important operational data source for several ice centres around the world. Whereas RADARSAT-1 is only capable of acquiring data at a single polarization, RADARSAT-2 will be capable of acquiring dual-polarization data in many wide-swath modes (most importantly ScanSAR) and fully polarimetric SAR data in a narrow 25-km swath mode. In thi...
متن کاملCapabilities of data assimilation in correcting sea surface temperature in the Persian Gulf
Predicting the quality of water and air is a particular challenge for forecasting systems that support them. In order to represent the small-scale phenomena, a high-resolution model needs accurate capture of air and sea circulations, significant for forecasting environmental pollution. Data assimilation is one of the state of the art methods to be used for this purpose. Due to the importance of...
