Abstract

The invention provides an ocean atmospheric optical parameter measurement method and equipment, and a computer device and a computer readable storage medium. The measurement method comprises the following steps of acquiring a first radiance when the sunlight enters the atmosphere; adjusting the orientation of an atmospheric optical probe, so that the center of the atmospheric optical probe can bealigned with the sun; controlling the atmospheric optical probe to acquire a second radiance; and calculating the atmospheric optical parameters according to the first radiance and the second radiance. According to the measurement method provided by the invention, the atmospheric optical parameters can be obtained, so that when a water environment is detected, the influence of the atmosphere on the measurement can be removed, so that the measurement accuracy is improved, and the monitoring effect of the water environment is further improved.

Description

technical field [0001] The invention relates to the technical field of optical detection, in particular, to a method and equipment for measuring optical parameters of ocean atmosphere. Background technique [0002] In real life, the distribution of aerosols varies greatly in time and space, especially in the offshore waters. The substances contained in aerosols are very complex, which affects the measurement of water color remote sensing data. In real life, the aerosol particles present in aerosols will have an impact on solar radiation, thereby affecting the measurement of water color remote sensing data, thereby reducing the accuracy of the measurement. [0003] However, in practice, the on-site observation of the above-mentioned aerosols usually relies on the observation by the observers using a handheld solar photometer to accompany the voyage, or the accumulation of observation data through aerosol observation stations, which makes the measurement of aerosols. There ar...
