The 2021 China Meteorological Modernization Science and Technology Expo, guided by the China Meteorological Administration and hosted by the Chinese Meteorological Society, has come to a successful conclusion. The First China Meteorological Modernization Technology Innovation and Entrepreneurship Competition in 2021 was also held in the same period. The "Air Pollution Cloud Platform" project from Jiufang Technology won the first prize.

The air pollution cloud platform provides data services in the way of cloud computing and is deployed on the most powerful supercomputer "Sunway · Taihulight" in China. It integrates the authoritative national pollutant data sources of environmental protection industry, routine monitoring elements of meteorological and air quality monitoring stations, grid micro-stations and navigation and other multi-dimensional data. Through cloud computing, big data and artificial intelligence technologies, To achieve the point, line, surface comprehensive pollutant scientific forecast, accurate source tracing and diffusion assessment functions.

Fast and accurate numerical simulation of air quality can be achieved. Provide users with nationwide district/county air quality forecasting, pollution forecasting, emergency scenario inference and assessment, pollutant source and diffusion analysis, and other customized services.

Core functions of air pollution cloud platform:

1. Pollution forecast. Through supercomputer and AI technology, the air quality and change trend in the next 1-7 days will be accurately measured, providing real-time and accurate forecast data for emergency management and control.

2. Simulation and deduction. Air quality is deduced for various emission reduction scenarios to provide guidance for accurate haze control.

3. Cause analysis. Review the historical status, accurately target key pollution sources, and scientifically and quantitatively assess the emission and impact trend of pollution sources.

The use of this platform will help improve the efficiency and effectiveness of environmental protection construction and environmental monitoring, and provide decision-making support for the formulation of economical and effective air pollution control strategies.
