Description

technical field [0001] The invention relates to a spectral measurement system, in particular to a polar sea ice profile spectral radiation measurement system based on a mobile spectrometer on a slide rail. Background technique [0002] The polar climate and polar sea ice environment have undergone dramatic changes in recent decades. Among them, sea ice has become a hotspot in polar research because of its significance to polar marine ecosystems, polar upper ocean processes, atmosphere-sea ice-ocean interactions, and global climate change. Studies have shown that over the past few decades, Arctic sea ice has undergone significant changes due to the combination of thermodynamic changes that have occurred in the Arctic over the past few decades and changes in the sea ice cycle. Among them, solar radiation plays a pivotal role. The massive melting of Arctic ice and snow and the increase of surface melting pools have resulted in a decrease in the overall albedo, accelerated the...

Problems solved by technology

With the advancement of science and technology, a small number of studies have used automated equipment to measure in recent years. Only a few studies have measured the internal solar radiation intensity profile of sea ice, but the techniques used in these studies often damage the in-situ environment of sea ice. Larger, and long-term in-situ measurement of the same place cannot be carried out, so the present invention is expected to overcome these difficulties, thereby promoting the development and progress of my country's polar marine equipment technology
