Abstract

The invention discloses a CO2 emission monitoring method and monitoring system. The method comprises the following steps: acquiring first data and second data; processing the first data by adopting an area weighted average method to obtain third data; processing the second data by adopting a time interpolation and spatial convolution method to obtain fourth data; matching the third data with the fourth data according to the 1km grid and time to form a training data set, and modeling by adopting a machine learning method to fill the comprehensive domain NO2 column concentration space-time distribution of the target area; matching the space-time distribution of the filled NO2 column concentration with the wind speed and the wind direction, and calculating by adopting a linear density fitting method to obtain the average NOx emission in each wind direction; the NOx emission amount is combined with a CO2-NOx scaling factor, and the CO2 emission amount is obtained; the method has the beneficial effects that the calculation accuracy of the CO2 emission amount and the dynamic updating frequency are improved, and real-time data support is provided for emission reduction and carbon reduction work.

Description

technical field [0001] The present invention relates to CO 2 The technical field of emissions, specifically, involves a CO 2 Emission monitoring method and monitoring system. Background technique [0002] Controlling greenhouse gas emissions and coping with climate change are major challenges for sustainable human development in the 21st century. Accurate calculation of CO 2 Emissions are the basis for promoting carbon reduction work, and can provide a basis for carbon emission statistics and accounting. Currently for CO 2 The calculation of emissions is mostly based on bottom-up methods based on statistics and surveys, that is, statistical accounting of emissions from various emission sources is carried out through relevant data such as industrial production, economic development and energy consumption. [0003] The "China High Spatial Resolution Emission Grid Database" refers to the international mainstream bottom-up spatialization method, and allocates space from the ...
