Buoy-based long-time on-line monitoring apparatus and method for sea cloud height

Abstract

The invention provides a buoy-based long-time on-line monitoring apparatus for the sea cloud height. The apparatus comprises a buoy; and a laser ceilometer, a buoy attitude measuring module, a cloud height correction and compensation module, a communication module, and a meteorology and hydrology observation sub system. The buoy attitude measuring module is used for measuring attitude parameters, like a heading parameter, a rolling parameter and a pitching parameter, of a buoy platform; the cloud height correction and compensation module is used for realizing cloud height observation correction and compensation based on the attitude parameters of the ceilometer; and the communication module is used for uploading the data that can be used by users. According to the invention, buoy-based laser radar cloud height observation is carried out and the measurement result is accurate and reliable; off-shore, long-term continuous, real-time, high-precision, high-temporal-spatial-resolution marine environment monitoring on the cloud height, cloud thickness, and conventional marine meteorology and hydrology can be realized; an accurate and reliable data support can be provided for scientific researches of marine atmosphere, weather forecasting, ocean shipping, and naval drills and the like; and thus the apparatus has important significance in development of multiple fields like the marine economy, the marine science and technology, and the legal rights safeguarding on the sea.

Description

technical field [0001] The invention relates to the field of marine environment monitoring, in particular to a device and method for long-term online monitoring of ocean cloud height based on buoys. Background technique [0002] Clouds are a common weather phenomenon. Clouds are the external manifestations of thermal and dynamic processes in the atmosphere, and they are also an important link in the water cycle. Clouds are not only an important weather phenomenon that affects daily work and life, but have also been identified as one of the most significant limiting factors threatening Air Force systems and mission success. Cloud observation plays a vital role in atmospheric scientific research and meteorological operations (such as analysis of weather, climate environment change, water vapor phase transition process, weather forecast, etc.). [0003] At present, cloud height observation methods mainly include artificial visual observation, balloon detection, aircraft detect...

AI Technical Summary

Problems solved by technology

Among them, manual observations on the shore have large human errors, and can only observe the cloud heights on the shore and near the shore, and cannot realize cloud height observations in the far sea; balloon observations take a long time, are costly, and have low temporal and spatial resolution, and cannot perform long-term continuous observation of clouds. And it is more difficult to operate at sea; aircraft detection is generally in the form of an airborne microwave radiometer, which can be flexibly maneuvered to achieve rapid observation in a certain area, but the cost is high and it is greatly affected by strong convective weather; space-based satellite observation mainly includes visible light, infrared, Microwave passive remote sensing and spaceborne ...
