| titleOfInvention | A method for monitoring the total amount of atmospheric formaldehyde slope in satellite remote sensing under low signal-to-noise ratio |
| abstract | The invention belongs to the technical field of air quality monitoring, in particular to a method for monitoring the total amount of atmospheric formaldehyde slope in satellite remote sensing under low signal-to-noise ratio. The method of the invention includes: extracting the average spectrum of a specific ocean area from a satellite spectrum file as a reference spectrum, taking into account the absorption of strong absorbing gas to perform on-orbit adaptive calibration, and obtaining a real-time instrument response function; and then using the reference spectrum as the initial light intensity, Characterize the characteristics of interference gas absorption with wavelength, and calculate the total formaldehyde differential slope: then subtract the abnormal value from the total formaldehyde differential slope to obtain the total formaldehyde slope. Aiming at the low signal-to-noise ratio of EMI and poor operation status of the first spaceborne spectrometer in my country, the method of the invention proposes a remote sensing technology for the total amount of atmospheric formaldehyde slope. Compared with the results without the method of the invention, the inversion error greatly reduced. |
