Problems solved by technology

Most of these atmospheric monitors monitor ozone with a narrow band, and rarely monitor other atmospheric trace gases
In addition, the spatial resolution of these instruments is low, and the pollution source cannot be accurately located. The global coverage of many instruments is insufficient, the return visit period is long, and the time resolution is low.

Abstract

The invention provides a comprehensive optical monitoring system, which comprises a telescope, an ultraviolet UV spectrometer, an ultraviolet visible UVIS spectrometer, a near-infrared NIR spectrometer and a short wave infrared SWIR spectrometer; the filed of view of the telescope is greater than 100 DEG; the working band of the telescope covers the outer band, the visible band, the near-infraredband and the short waved infrared band; the UV spectrometer, the UVIS spectrometer and the NIR spectrometer use the raster to divide light; the SWIR spectrometer uses the immersion raster to divide light; and, the UV spectrometer, the UVIS spectrometer, the NIR spectrometer and the SWIR spectrometer share the telescope. The application provides a comprehensive optical monitoring system with wide spatial coverage area, high spatial resolution, wide band and high spatial resolution.

Description

technical field [0001] The invention relates to the technical field of atmospheric spectral radiation detection, in particular to an integrated optical monitoring system. Background technique [0002] So far, climate and environmental disasters caused by the deviation of the earth-atmosphere system from its quasi-equilibrium state (such as global warming has been recognized as a fact) have seriously threatened the sustainable development of human society. In order to study the interrelationship between human activities, the Earth system and the space environment, global change and its scientific basis "Earth System Science" has become the focus and hot issue of current interdisciplinary research. In order to understand and solve this problem, one of The important means are to use various sensors (from ultraviolet to microwave, radio wave) to conduct long-term, large-scale and high-precision dynamic monitoring of the earth's surface and atmospheric system as a whole, especial...
