4. Scope of application:Suitable for comprehensive three-dimensional monitoring and analysis and evaluation, quality control/quality assurance, data integration and display of regional atmospheric environment quality and pollution distribution characteristics.

5. Technical content:

This technology includes advanced environmental monitoring technology and equipment such as detection of temporal and spatial distribution of atmospheric pollution components and fine particulate matter, automatic monitoring of multi-component pollutants in chemical parks, airborne telemetry of regional distribution of polluted gases, and online monitoring of atmospheric fine particulate matter. It realizes rapid, real-time detection of atmospheric trace gases, atmospheric aerosols, greenhouse gases, atmospheric wind fields, water vapor, temperatures and various atmospheric pollution components, networked online quality control technology, data integration and display, etc. Through the remote sensing characteristics of light waves, multi-scale detection, online quality control, multi-dimensional visualization integration and display of various atmospheric components and atmospheric parameters are carried out on ground-based, vehicle-mounted, airborne and satellite-borne multiple platforms.

This technology can obtain a large amount of high-resolution spatio-temporal change information of air pollution, making up for the shortcomings of conventional operational monitoring networks in monitoring methods, monitoring content, monitoring scope and monitoring indicators, and has high sensitivity, high resolution, high selectivity, advantages such as multi-component, multi-dimensional visual integrated display and real-time, providing solid basic data support for regional air pollution characteristics research and air quality improvement effectiveness evaluation.

6. Technology demonstration and application promotion:

Serving large-scale national events (2010 Guangzhou Asian Games, 2011 Shenzhen Universiade, 2014 Beijing APEC Conference, 2015 93 Military Parade, 2016 Hangzhou G20 Summit, 2017 Xiamen BRICS International Summit, 2017 Guangzhou Fortune Forum, 2018 Boao Forum for Asia) Air quality assurance and "Addressing the Causes and Treatment of Heavy Atmospheric Pollution" task, the products are used in batches in the Urban Air Quality Automatic Monitoring Network of the Ministry of Ecology and Environment, Super stations for monitoring atmospheric haze in key areas and cities and the meteorological observation network of the China Meteorological Administration have achieved an additional annual output value of more than 800 million yuan.

It has taken the lead in establishing a cross-regional three-dimensional monitoring network for composite air pollution in the Guangdong-Hong Kong-Pearl River Delta region, an atmospheric super monitoring station that combines scientific research and business, and my country's first regional air joint prevention and control technology demonstration zone, supporting the implementation of new national air quality standards in the Pearl River Delta and Guangdong Province. The real-time networking and release technology of air quality monitoring data has also been gradually promoted and applied to 338 cities above prefecture level and Hong Kong and Macao across the country. Supported Guangdong, Hong Kong and Macao in establishing a long-term cooperation mechanism in air quality management and joint research on air pollution prevention and control,

7. Estimation of investment and operating costs

The investment cost of this technology is closely related to the price of imported components, the number of monitoring stations, the type of monitoring indicators, instrument configuration and operation and maintenance. On the basis of gradually providing localization rates, costs can be effectively reduced. There are many related monitoring equipment, and the overall investment and operating costs are estimated to be about 100 - 200 million yuan. This technology is mainly composed of automatic online instruments with low maintenance and operation costs.

8. Investment payback period

The payback period is 1-3 years.

9. Prospects for achievement transformation and promotion

This technology has achieved stable commercial application in 338 cities above prefecture level across the country, and has been promoted to Hong Kong and Macao. In the future, it will also provide strong support for the construction of regional ecological environment monitoring networks and has broad application prospects in the field of environmental protection.

This technology is in the stage of demonstration application and preliminary industrialization, and has broad application prospects in the fields of environmental protection and meteorology.
