Regional Emission inventory in ASia (REAS)
Data Download Site

For the analysis of long-term trends of the Asian atmospheric environment, the first inventory of historical and future projected emissions in Asia, the Regional Emission inventory in ASia (REAS) 1.11 has been developed and opened since 2007. Recently, we have updated the REAS inventory and opened as version 2.1 in this website. Datasets of Regional Emission inventory in Asia for Persistent Organic Pollutants (REAS-POP) 1.0 which focuses on polycyclic aromatic hydrocarbons (PAHs) in North east Asia are also provided.

@General Information

REAS2.1

Species: SO2, NOx, CO, NMVOC, PM10, PM2.5, BC, OC, NH3, CH4, N2O, and CO2

Years: 2000-2008

Area:
East, Southeast, South, and Central Asia. Asian part of Russia (Far East, Eastern and Western Siberia, and Ural)

Emission sources:
Fuel combustions in power plants, industry, transport, and domestic sectors; Industrial process; Agricultural activities (fertilizer application and livestock); and Others (fugitive emissions, solvent use, human, etc.)

Spatial resolution: 0.25 degree by 0.25 degree

Temporal resolution: Monthly

Japan:
Emissions except for the maritime sector were from the Japan Auto-Oil Program (JATOP) Emission Inventory-Data Base (JEI-DB) developed by JPEC (2012a, 2012b, 2012c). Emissions from the maritime sector were taken from the database developed by the Ocean Policy Research Foundation (OPRF, 2012). The maritime emission data were developed under the project named ethe comprehensive project of assessment for improving the air quality by establishment of the emission control areas (ECA) in Japanf, which is supported from the grant by the Nippon Foundation derived from revenues from motorboat racing. NMVOC evaporative emissions from stationary sources in Japan were from data developed by Ministry of the Environment of Japan (MOEJ, 2009).

Korea, Rep. of:
Emissions relied on the Clean Air Policy Support System (CAPSS) developed by Lee et al. (2011). Data were taken from the National Air Pollutants Emission website maintained by the National Institute of Environment Research-Korea.

Taiwan:
Emissions data sets were obtained from the Environmental Protection Administration of Taiwan at its website.

EDGAR 4.2:
Datasets for aviation (both domestic and international at altitude less than 1km) and international navigation were taken from EDGAR 4.2 (EC-JRC/PBL, 2011). Emissions related to agricultural activities for Asian Russia and Central Asia were also obtained from EDGAR 4.2.


REAS POP 1.0

Species:
fluoranthene (Flu), pyrene (Pyr), benz[a]anthracene (BaA), chrysene (Chr) benzo[b]fluoranthene (BbF), benzo[k]fluoranthene (BkF), benzo[a]pyrene (BaP), indeno[1,2,3-cd]pyrene (IcdP), benzo[g,h,i]perylene (BghiP))

Years: 2005

Area: Northeast Asia (China, Far East Russia, North Korea, South Korea, Mongolia, Taiwan, Japan)

Emission sources:
Fuel combustions in power plants, industry, transport, and domestic sectors; Industrial process; and Open biomass burning*

*Fuel consumption rates were derived from REAS 1.11. PAH emission from open biomass burning was estimated using the burned area, the BC emission rate, and the PAH and BC emission factors. The burned area and the BC emission rate were derived from GFEDv3.

Spatial resolution: 0.5 degree by 0.5 degree

Temporal resolution: Monthly
