AMSR-E advanced wind speed retrieval algorithm and its application to marine weather systems
The physical-based algorithm for the sea surface wind speed W retrieval from Aqua AMSR-E passive microwave measurements is considered. The brightness temperatures TBV(24) at 23.8 GHz and TBV(36) at 36.5 GHz with vertical (V) polarization and TBH(11) at 10.7 GHz with horizontal (H) polarization and results of computations of the brightness temperature of the calm ocean surface TBocH(11) are used at first to estimate contribution of the atmosphere to TBH(11), then increment of TBocH(11) caused by wind action and at last wind speed. The developed algorithm is applied to AMSR-E data obtained in the Northwest Pacific Ocean over extratropical cyclones with gale winds. The retrieved fields of wind speed are compared with scatterometer-derived fields and the surface analysis maps.
