MIX Asian emission inventory was developed by the MEIC teamMIX亚洲人为源排放清单正式发布

MEIC team recently released an Asian emission inventory, MIX, in years of 2008 and 2010. MIX was developed to provide up-to-date model-ready emissions for multiple chemical transport models and climate models. Integrating latest MEIC, REAS2, PKU-NH3, and CAPSS emission inventories, MIX covers ten air pollutants and greenhouse gaseous (SO2, NOx, CO, NMVOC, NH3, PM10, PM2.5, BC, OC and CO2) with a resolution of 0.25 degree at Asia scale. MIX recently has been used to support MICS-Asia (Model Inter-Comparison Study for Asia) and TF HTAP (Task Force Hemispheric Transport of Air Pollution) projects as the base emission inventories for modeling. Gridded emissions of MIX can be accessed here.

MEIC模型团队为东亚模式比较计划(MICS-Asia)开发的2008年和2010年亚洲排放清单产品MIX于近日正式发布。MIX清单旨在为大气化学模式和气候模式提供最新、最精确的排放清单数据,采用集合开发方法,集成了MEIC、REAS2、PKU-NH3、CAPSS等亚洲各地区最新的排放清单成果,建立了涵盖10种大气污染物和温室气体、以2008和2010年为基准年的0.25度分辨率网格化排放清单。目前,MIX清单已用于支持东亚模式比较计划第三期(MICS-Asia Ⅲ)的模拟研究,并被联合国半球大气污染传输计划(HTAP)采用。点击这里下载MIX网格化清单。

The MEIC model contributes to the national emission inventory guidelines MEIC模型为国家排放清单编制技术指南体系提供支撑

The development of a complete emission inventory is an essential step in an air quality management process. To guild local governments, China’s Ministry of Environmental Protection (MEP) recently issued a series of air pollutants emission inventory guidelines for developing national and local emission inventories. The guidelines consist of four types of air pollutants (i.e., PM2.5, VOCs, NH3 and PM10) and four emission sources (i.e., on-road vehicles, off-road vehicles, biofuel combustion and dust). The MEIC team in Tsinghua University, as the technical supporter, intensively participated in systematic design of the guidelines and also proposed guidelines in details.


China’s MEP initiated the “emission inventory guideline” project since 2013, after the occurrence of two severe air pollution episodes. Prof. Kebin He, chair of the MEIC team, took charge of technical work of the project, and proposed working procedure for emission inventory establishment. He raised that individual emission inventory, in terms of air pollutants or sources, should be developed firstly over China. As the methods are widely understood and accepted, the final comprehensive guideline for different pollutants from multi-sources, with the accurate spatial and temporal information from point sources, then can be implemented, replacing the separated ones. So far, eight emission guidelines have been successfully issued and widely used in local governments. The MEIC team was in charge of the guidelines of PM2.5 and PM10 and participated in preparation of several others. Moreover, faced with the gradually higher demand of emission inventory from local governments, the MEIC team currently has begun to compile the guidelines for comprehensive emission inventory which include different pollutants from multi-sources and offers high spatial and temporal resolutions.
