Offshore haze remote sensing identification method and system under clear sky condition

Abstract

The invention discloses an offshore haze remote sensing recognition method and system under a clear sky condition, and relates to the field of ocean remote sensing data and application, and the methodcomprises the steps: obtaining ocean overhead satellite remote sensing data corresponding to a monitoring area under the clear sky condition; extracting a pixel spectral characteristic value according to the satellite remote sensing data above the sea; and according to the pixel spectral characteristic value and a trained neural network haze remote sensing identification model, determining the haze distribution above the sea corresponding to the monitoring area. The trained neural network haze remote sensing recognition model is obtained by training an MLP neural network model according to sample data; wherein the sample data comprises types of pixel regions and pixel spectral characteristic values corresponding to the pixel regions; the types include clean water, turbid water and haze. According to the invention, satellite remote sensing data over the sea are combined with a neural network machine learning algorithm, so that the purpose of accurately and effectively monitoring the haze distribution over the sea is achieved.

Description

Technical field [0001] The invention relates to the field of ocean remote sensing data and application, in particular to a remote sensing identification method and system for maritime haze under clear sky conditions. Background technique [0002] In recent years, the occurrence of smog has become more frequent and the range affected by smog has become wider. The smog has caused destructive effects on human travel, health, and the ecological environment. It has caused government departments, The widespread attention of scientists and society has become a hot topic. [0003] As an important part of the global climate system, the ocean has an important impact on global climate change. my country borders the Pacific Ocean and is a large maritime country. At the same time, the eastern coastal area is where my country's economic and social development is relatively fast, and it is also my country's main economic contribution area. About 60% of the country's population is located in the ...
