Method for quickly calculating atmospheric CO2 concentration based on satellite infrared remote sensing

Abstract

The invention discloses a method and a system for quickly calculating atmospheric CO2 concentration based on satellite infrared remote sensing. The method comprises establishing a non-parameter statistical model and an inversion system. The step of establishing the inversion system further comprises a data compression substep for extracting major spectral signal structure characteristics, a data matching substep for observing the matching of information, a calculation model establishing substep for establishing a multi-layer feedforwardneural network, and a quality control substep for performing quality control to reduce the error of an input sample. The step of concentration calculation further comprises an estimation request substep for preprocessing estimation input data, and an estimation substep for estimating according to the estimation request and outputting an estimation result. According to the method, the spectral absorption-radiation transfer physical relationship is simulated by virtue of the artificial neural network based on the forward model, and a system with an efficient greenhouse gas inversion mode and capable of visually displaying the inversion result is provided.

Description

technical field [0001] The invention relates to the field of earth science computing, in particular to a method for quickly calculating atmospheric carbon dioxide concentration and a visualization system. Background technique [0002] carbon dioxide (CO 2 ) is an important greenhouse gas, although it accounts for less than 0.05% of the total atmosphere, it can absorb the infrared radiation emanating from the surface, so the increase in the concentration of carbon dioxide will lead to an increase in the temperature of the earth's surface. Since the industrial revolution, due to the impact of human activities (such as deforestation, agricultural activities and burning of fossil fuels, etc.), the global greenhouse gas emissions and concentrations have continued to increase, and the concentration of carbon dioxide in the atmosphere has increased from 280ppm to 379ppm. Carbon dioxide and other greenhouse gases also affect the ozone layer and water vapor in the atmosphere, which ...
