渤海与东海云雾屏障及其对遥感海洋信息有效性的研究

本文阐述了渤海与东海云雾屏障作用,使海区能见度降低,即使是中小尺度的海洋信息,历经多年的NOAA卫星监测,均已表明了无论空间分辨率或时间分辨率,能够较完整的获取这一遥感“天窗”信息则概率很低.笔者,结合渤海与东海的云雾和区域海洋特征,NOAA卫星信息的多波段、多时相特点,建立了信息需求分析模型,并示出渤海和东海海洋遥感“天窗”信息的概率排队.

Cloud and Mist Screen Over Bohai and East China Seas and Its Validity Research for Remotely Sensing Ocean Information

This paper expounds the screened role of cloud and mist over Bohai and East China seas which has reduced the visibility over the above seas. Even if a middle and small scale oceanic information that has been monitored by the NOAA satellites for many years, a little probability has been indicated regardless of spatial or temporal resolution being able to completely acquire the remotely sensing "skylight" information. The author has established the analytic model for information requirement system combined cloud and mist over Bohai and East China seas and their regional characteristics of ocean with the multiband and multitemporal properties of NOAA satellite data and showed that the "skylight" information of remote sensing of the Bohai and East China seas is arranged in the order of probability. Besides, the scientific basis for selecting the best time and its necessity has been treated.
