Abstract

The invention relates to a method and a system for monitoring CO2 hourly emission of an emission source in a target area by a satellite. The method comprises the following steps: acquiring position information of the target emission source in the target area, XCO2 concentration information acquired by the satellite, and meteorological information corresponding to the XCO2 concentration information; selecting a preset area meeting a CO2 concentration condition according to the XCO2 concentration information, and constructing an observation window; constructing an XCO2 relation function according to the XCO2 concentration information in the observation window and the observation point distance information; according to the XCO2 relation function, the atmosphere total water vapor content, the near-ground pressure intensity and the ground wind speed, the CO2 hourly emission amount of the target emission source is obtained; the CO2 hourly emission in the downwind direction of a known emission point source is monitored in a large area through satellite remote sensing, and the manpower and material resource cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of atmospheric environment air quality monitoring. Specifically, it involves a satellite monitoring target area emission source CO 2 Hourly emissions method and system. Background technique [0002] carbon dioxide (CO2) in the atmosphere 2 ) is the most important greenhouse gas, and its concentration is increasing mainly due to human activities. Accurately quantify CO 2 It is crucial to address the challenges posed by global climate change. As of September 2018, the 195 members of the United Nations Framework Convention on Climate Change (UNFCCC) signed the Paris Agreement, whose long-term goal is to keep the rise in global average temperatures below 2°C relative to pre-industrial levels. Action is needed to reduce anthropogenic greenhouse gas emissions (including CO 2 ) halved. [0003] However, there are still significant uncertainties in anthropogenic emissions, and there is currently no global observing sys...
