EMEP European anthropogenic emissions
EMEP emissions have been superseded by CEDS global emissions.
On this page we provide information about The Co-operative Programme for Monitoring and Evaluation of the Long-range Transmission of Air Pollutants in Europe (EMEP) anthropogenic emissions inventory for Europe.
Overview
The EMEP inventory includes annual anthropogenic emissions of CO, NH3, NOx, and SOx for 1990-2005. This inventory also includes emissions of CO, NH3, NOx, and SOx from ship exhaust.
The data files were obtained from the EMEP website and processed by Aaron van Donkelaar.
In GEOS-Chem v10-01 and newer versions, the EMEP anthropogenic and ship emissions are read with the HEMCO. We have created EMEP data files COARDS-compliant netCDF format for use with HEMCO.
Discussion following 1-month benchmark v10-01h
The 2008-2010 updated EMEP emissions were validated in GEOS-Chem v10-01h. The following discussion ensued.
Aaron van Donkelaar wrote:
- I'm a little surprised at the drop of more than 50% in anthropogenic SO2 and NO over Europe.
- I decided to explore the large drop in emissions and have found the drop in the revised EMEP emissions that are presently available to be much lower in than what EMEP had estimated when I downloaded/reformatted the original dataset back in 2011.
- It should be fairly straightforward for me to reprocess new EMEP input files based on their latest estimates, which run until 2012, if the old format is still useful post-HEMCO.
- For now I would not recommend using the EMEP files originally slated as part of this update. Rather, I would suggest that I/we update the emission based on the latest EMEP inventory.
Update 3/31/15: Aaron has reprocessed EMEP emissions for 1990-2012. Please see this wiki post for more information.

Reprocess EMEP emissions for 1990-2012
This update was validated with the 1-month benchmark simulation v10-01i and approved on Approved 01 May 2015.
The original updated EMEP emissions for 2008-2010 (generated in 2012) were found to be too low in 1-month benchmark v10-01h, so Aaron van Donkelaar reprocessed EMEP anthropogenic and ship emissions of CO, NH3, SO2, and NO for 1990-2012. The reprocessed data file is in netCDF format and includes data that has been mapped from the original 50 km grid x 50 km grid onto a 0.1° x 0.1° grid. Regridding to the finer 0.1° x 0.1° resolution allowed these input files to maintain a reasonable representation of their original grid characteristics, thereby permitting HEMCO to more accurately regrid onto a variety of GEOS-Chem grids. This file is read with the HEMCO and was validated with 1-year benchmark v10-01h-Run0.
EMEP European ship emissions inventory
The EMEP inventory contains ship emissions for CO, NH3, SOx, and NOx.
Please also note the following fixes that are relevant for GEOS-Chem v9-01-01 or older versions:
- Bug with EMEP ship emissions for nested grids
- Bug fix for EMEP ship emissions
- Fix for initialization of EMEP ship emissions
- Inconsistent mask file for EMEP ship emissions
1980 to 1989
EMEP ship data from 1980-1989 emit NOx as pure NOx (and not HNO3 + 10*O3). It was not possible to separate the NOx into HNO3 and O3 from this data set.
See Auvray and Bey [2005] and Vestreng and Klein [2002] for more information.
1990 to 2005
EMEP ship data from 1990-2005 are based on Vestreng et al. [2007].
