The invention relates to a gaseous pollutant concentration column conversion method and device, belonging to the technical field of environmental pollution monitoring. The method obtains the four-dimensional grid point data forecast result of the physical quantity through model forecasting, and screens the preset in the four-dimensional grid point data forecast result. The four-dimensional grid point forecast result of gaseous pollutant concentration, according to the preset four-dimensional grid point forecast result of gaseous pollutant concentration, is processed by the meteorological mapping system to obtain the preset layer preset gaseous pollutant concentration text file, and the layer-by-layer text file is used as the input field , according to the summation method, the conversion of the model layer data to the column concentration is carried out, and the column concentration of the tropospheric ozone concentration is obtained. Through conversion, the ozone concentration in the model layer can be converted into the tropospheric ozone column concentration, which reduces the ozone concentration from four dimensions to three dimensions, further clarifies the physical meaning of the ozone column concentration, improves the forecasting efficiency of the tropospheric ozone concentration in the atmospheric chemical model, and improves the The application effect of scientific research and business units in environmental protection and meteorological industries.
Description
technical field [0001] The invention belongs to the technical field of environmental pollution monitoring, and in particular relates to a gaseous pollutant concentration column conversion method and device. Background technique [0002] Compared with stratospheric ozone ("good ozone"), troposphere ("bad ozone") can form acid rain and photochemical smog, which is second only to CO2 and CH4 as a greenhouse gas and one of the main air pollutants that directly endanger human health and the ecological environment one. Therefore, fully understanding and studying tropospheric ozone is a necessary way to solve air pollution. As the troposphere is an atmosphere that is closely related to human life, its ozone column concentration is the most direct physical quantity that reflects the change of troposphere ozone distribution. [0003] At present, the ozone concentration generated by the atmospheric chemical model forecast / simulation is the volume mixing ratio of each model layer, an...
