本文介绍了一种利用NOAA系列气象卫星上AVHRR成像传感器的短波波段对世界许多地区沿海沃茨发生的强烈浮游生物水华（“赤潮”事件）进行实时测绘的方法。在开阔海洋中也使用了类似的方法来探测颗石藻引起的高反射水华，但高级甚高分辨率辐射计探测表面沃茨明显变亮的其他事件的能力似乎被忽视了。本文介绍了如何从本地接收站的数据的实时处理，可用于“赤潮观察”的频繁和快速监测大面积。文中介绍了该处理算法的优点和局限性，并对样本数据进行了讨论.
This article presents a method for using the short wave bands of the AVHRR imaging sensor on the NOAA series of weather satellites for real-time mapping of the intense plankton blooms (''red tide'' events) that occur in the coastal waters Of many parts of the world. A similar method has been used in the open ocean to detect the highly reflective blooms due to coccolithophores, but the capabilities of the AVHRR for detecting other events in which surface waters are significantly brightened appear to have been overlooked. The article describes how real-time processing of data from a local receiving station may be used in a ''red tide watch'' for the frequent and rapid monitoring of large areas. The advantages and limitations of the processing algorithm are described, and sample data are discussed.
