Abstract

The invention provides a temperature profile fine measurement sensor for a water boundary layer of a sea-gas interface. The sensor comprises a sealed shell, a temperature measurement array is disposedin the sealed shell, and end face sealing is adopted between the temperature measurement array and the sealed shell. Pressure sensors are arranged at the top and the bottom of the sealed shell, the pressure sensor at the top is used for measuring sea surface air pressure, and the pressure sensor at the bottom is corrected through an established error compensation model. A measuring circuit, an attitude measuring module and a circuit board support are further arranged in the sealed shell, and radial sealing is adopted between end covers and the sealed shell and between the pressure sensors andthe end covers. The sensor can perform high-precision contact measurement on a seawater temperature field within the depth of 0-0.1m of a water boundary layer of a sea-gas interface, and can be usedfor on-orbit calibration of satellite remote sensing and SST authenticity inspection.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a temperature profile fine-grained measurement sensor for the water boundary layer at the air-sea interface. Background technique [0002] The solar radiant energy absorbed by the seawater within the depth of 0-0.5m in the air-sea interface water boundary layer accounts for 50% of the total amount of solar radiant energy penetrating into the ocean. play an important role. The response of its temperature field to the forcing of the air-sea interface is of great scientific significance for in-depth understanding of the air-sea interface process, improvement of ocean mixing and air-sea flux parameterization schemes, etc. In addition, processes such as sea-air temperature difference, wind speed, rainfall, and waves will all have an impact on the temperature and flow field structure in the water boundary layer at the air-sea interface. Therefore, the temperature fiel...
