Emission Data for China

1. The MarcoPolo Inventory for East China:

The MarcoPolo inventory provides monthly emissions for the year 2014, for the pollutants NOx, PM2.5, PM10, BC, SO2, VOCs, NH3 and CO, for East- and Central China on a 0.25 degree resolution. The emissions are categorized in six different sectors: industry, residential, energy, transport, agriculture and international shipping. The inventory is mainly based on top-down satellite emission estimates for the year 2014, and source sector information of existing bottom-up inventories.

A high resolution inventory (0.01 x 0.01 degree resolution) has been compiled for three selected regions: the Beijing-Tianjin area, the Yangtze river delta and the Pearl River delta. The high resolution inventory is obtained by downscaling the 0.25 degree resolution inventory using proxy data.

An elaborate description can be found here. The low and high resolution MarcoPolo emission inventories can be downloaded after registration.

Wildfire PM2.5 emissions

3. Bottom-up inventories:

The MEIC emission database

The the Multi-resolution Emission Inventory for China (MEIC) is a bottom-up inventory with monthly emission data for the region of China. It can be used to support chemical transport model and climate models at different spatial resolution and time scale.

More information and data can be found at http://www.meicmodel.org

The ECCAD emission database

The goal of the ECCAD (Emissions of Atmospheric Compounds & Compilation of Ancillary Data) database is to provide scientific and policy users with a large set of data on surface emissions of gaseous and particulate chemical species, as well as with ancillary data required to quantify and analyze surface emissions. ECCAD provides user-friendly access to global and regional emission inventories, ancillary data, and tools for the analysis and evaluation of these data.

ECCAD can be accessed through http://pole-ether.fr/eccad. Emissions available in ECCAD can be downloaded in NetCDF format. All the files are fully CF-compliant (see unidata.ucar.edu for more information). Several tools are available in ECCAD for the visualization and the analysis of emissions and ancillary data.

Recently the second version of the ECCAD database was developed and is already available at http://eccad.aeris-data.fr. It contains, inter alia, the two emission data sets REAS1.1 and REAS2.1 (Regional Emission inventory in ASia).
