在海洋气象资料中,气压是重要的参数之一。以往,海洋气压的测量一般由观测船进行,或由海洋台站测量再推延到海面。前者多用空盒气压表,测量精度一般都不高,而且受测量环境影响;后者多用水银气压表,它的测量精度高,但要进行多种修正,安装使用也麻烦。而目前要在浮标上直接使用这些方法都有困难,也难以获得满意的测量结果。 Atmospheric pressure is one of the important parameters in marine meteorological data. In the past, the measurement of the pressure of the ocean was generally carried out by an observation vessel or measured by the ocean station and then extended to the sea surface. The former use empty box barometer, the measurement accuracy is generally not high, but also by the measurement environment; the latter with mercury barometer, which measures the high precision, but to carry out a variety of amendments, the installation is also in trouble. At present, it is difficult to use these methods directly on the buoys and it is difficult to obtain satisfactory measurement results.
