Emission inventory processing method of city-scale high-resolution model based on SMOKE model

Abstract

The invention discloses an emission inventory processing method of a city-scale high-resolution model based on a SMOKE model, which comprises the following steps: S1, acquiring emission inventory data; S2, generating a template according to the data requirements of the SMOKE model; S3, converting the template generated in the step S2 to the format required by the SMOKE mode; S4: consolidation of combing of multiple emission inventory files; 5, establishing an administrative division code file; S6: correction of the use of the CMAQ model in inland areas requiring the mandatory provision of waveemission documents; S7, generating a KML tag file of point source emission data; S8, creating a SMOKE model run script that matches the urban emission inventory and merging it into the four-dimensional X-Y-Z-T emissions NetCDF format emission data. The invention can meet various scientific research and business requirements based on air quality model, such as pollution source analysis, control measure assessment, environmental impact assessment and the like.

Description

technical field [0001] The invention relates to a method for processing an urban-scale high-resolution model emission inventory based on a SMOKE model. Background technique [0002] With the increasing attention to air quality in my country, the application of numerical air quality models in China is increasing year by year. The intervention solves the response relationship between pollution discharge and environmental concentration, making quantitative determination of the impact of man-made pollution sources and natural pollution sources on air quality concentration a reality, and the core basis for the application of air quality models is to compile and establish a local air pollutant model discharge list. [0003] Since the air pollutant emission inventory involves many types of emission sources, it can theoretically include all human activities that produce gaseous pollutant emissions, such as road motor vehicles, road dust, domestic coal burning, domestic gas, straw bur...

Problems solved by technology

There are some defects in each of the three methods. Although the mature open-source emission model can carry out the entire process of model emission inventory processing in the most complete way, and can better connect with the open-source air quality model, the current open-source emission models are all aimed at foreign emission inventories. The compilation system is complex and difficult to apply locally; while the self-developed emission inventory processing model requires a deeper understanding of the emission inventory processing model, and develops corresponding modules in combination with local da
