摘要: 利用气象卫星红外照片提取无云海区的海面温度信息,进而对海洋锋面、海流、上升流、涡漩等进行观测与研究,已为许多海洋学家所重视(Legeckis,1978).在人造卫星出现之前,要得到海面温度模式的大尺度同步测量资料是不可能的.船舶本来就不能以所要求的时间和空间复盖来进行这样的测量.Abstract: The images taken from several meteorological satellites form an important data source in the field of "oceanography from space".The image from the meteorological satellite IR band taken on a cloudless day provides information on the sea surface temperature field.But the raw BWIR images received directly by ground stations show little difference among grey levels of the sea and unsuitableness for plotting sea surface isotherms.With a Phosdac 1000 digital culour analyzer, the writer processed the images of the Japanese Geostationarp Meteorological Satellite GMS-1 IR band (10.5-12.6μ) and those of the U.S.Meteorological Satellite NOAA-5 IR band (10.5-12.5μ) to emphasize the informations of the sea surface temperature (SST) which are then taken as a basis to plot sea surface isotherms.
