Abstract

The invention discloses a marine-atmosphere integrated hyperspectral radiation measurement system and method. The system includes: an optical measurement unit: used to collect and measure hyperspectral radiance data; a scanning step control unit: used to control hyperspectral radiance data Rotation of the optical measurement unit during acquisition; control box: used for data acquisition, storage and transmission, as well as position calculation and driving stepper motor; solar panel: used to provide power for the measurement system; fixed bracket: used to connect the measurement system Fixed in position where hyperspectral radiometry is required. The measurement system designed by the invention avoids the use of different equipment to measure the radiation of the atmosphere and seawater separately, reduces the cost of equipment purchase, use and maintenance, and can automatically realize the optimal observation of the sun, sky and sea surface through the control program.

Description

technical field [0001] The invention belongs to the technical field of ocean optical observation, and in particular relates to an ocean-atmosphere integrated hyperspectral radiation measurement system and method. Background technique [0002] The surface area of ​​the global ocean accounts for about 71% of the total area of ​​the earth, and it plays an important role in the utilization of human water resources, the regulation of the global carbon cycle, and global climate change. Satellite ocean remote sensing is the main technical means to continuously obtain ocean parameters over a large area. For example, satellite optical ocean remote sensing technology can obtain the distribution of phytoplankton in the upper ocean layer characterized by chlorophyll concentration in a short period of time (1-2 days). Since the atmosphere plays a major role in the signals obtained by satellite optical ocean remote sensing, a key technology in satellite optical ocean remote sensing is to...
