Abstract

The invention relates to a gaseous pollutant concentration column conversion method and device and belongs to the technical field of environmental pollution monitoring. The method herein comprises: acquiring four-dimensional lattice data prediction results of physical quantity through model prediction, screening the four-dimensional lattice data prediction results to obtain preset gaseous pollutant concentration four-dimensional lattice prediction results, acquiring preset gaseous pollutant concentration text files of preset layers through processing of a meteorological plotting system according to the preset gaseous pollutant concentration four-dimensional lattice prediction results, converting model layer data into column concentrations according to a sum method by using the layerwise text files as an input field so as to obtain tropospheric ozone column concentrations. The model ozone concentrations can be converted into tropospheric ozone column concentrations by converting; the ozone concentrations are decreased from four dimensions to three dimensions; physical significance of the ozone column concentrations is further clarified; tropospheric ozone concentrations in an atmospheric chemical model can be predicted more efficiently; application effect in scientific research and business units in environmental protection and meteorological industries can be improved.

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] Relative to stratospheric ozone ("good ozone"), tropospheric ("bad ozone") can form acid rain and photochemical smog, second only to CO 2 and CH 4 Greenhouse gases and one of the main air pollutants that directly endanger human health and the ecological environment. 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, and the troposph...
