Abstract

The invention discloses a satellite remote sensing identification method and system for stratospheric ozone intrusion into the middle and lower layers of the troposphere. Simultaneous inversion of thermal infrared hyperspectral data to obtain vertical profile data of carbon monoxide and relative humidity, considering consistency issues, using thermal infrared hyperspectral data to simultaneously invert vertical profiles of ozone, carbon monoxide and relative humidity, combined with ground monitoring station data and position The vertical distribution of eddies can be used to accurately judge the event of stratospheric ozone intrusion into the middle and lower troposphere, and provide data support for the analysis of the causes of near-surface ozone and pollution control.

Description

technical field [0001] The invention relates to the field of ozone detection, in particular to a satellite remote sensing identification method and system for stratospheric ozone intruding into the middle and lower layers of the troposphere. Background technique [0002] In the atmosphere, 90% of ozone is concentrated in the stratosphere, forming a protective layer that reduces the ultraviolet radiation from the sun reaching the earth's surface, and 10% of ozone exists in the troposphere. Therefore, in order to analyze the causes of regional ozone pollution and control the ozone concentration near the ground, in addition to considering local emissions, it is also necessary to monitor the vertical distribution of ozone concentration in the large-scale space atmosphere, and further identify and judge the impact of stratospheric ozone intrusion into the middle and lower troposphere. [0003] The environment of high temperature, low humidity and low wind speed is conducive to oz...

Problems solved by technology

However, at present, due to the lack of vertical profile data of ozone, carbon monoxide and relative humidity at the ground air quality monitoring stations, the scarcity of ground-based remote sensing and sounding data, the coverage is insufficient, and the model simulation has large errors in the middle and lower tropospheres, so it is impossible to make accurate judgments

[0004] At present, only ground air quality station monitoring data, a small amount of ground-based remote sensing and sounding data, and atmospheric models combined with meteorological conditions can be used to judge the process of stratospheric ozone intrusion into the troposphere. However, due to the lack of ozone vertical profile data in ground air quality station monitoring, Including carbon monoxide and relative humidity vertical profile data with anti-phase relationship during the stratospheric ozone intrusion process; although ground-based remote sensing and sounding data can detect the vertical distribution of ozone concentration, due to the scarcity of observation data and uneven spatial distribution, it is impossible to Covering a large-scale range, there is currently no perfect system and method that can accurately identify and judge when and where the event of stratospheric ozone intrusion into the middle and lower troposphere occurs
