摘要: This paper describes a new regional ice analysis system developed at Environment Canada. It is primarily designed to satisfy the requirements for planning of marine transportation and other operations in ice-infested waters around North America, including Canada's two Arctic Metareas; sea-ice model initialization; needs numerical weather prediction models. A three-dimensional variational approach (3D-Var) used assimilate various types observations. In this first version, only analyses concentration are produced approximately 5 km resolution using 6 h persistence forecast from previous as background state. The assimilated observations concentrations sources passive microwave satellite data, Advanced Microwave Scanning Radiometer-Earth observing (AMSR-E) Special Sensor Microwave/Imager (SSM/I), manually derived charts Canadian Ice Service (CIS). Objective verification scores computed...
