EMEP European anthropogenic 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 also includes emissions from ship exhaust.

NOTE: The EMEP emissions data have been extended to the year 2007 in GEOS-Chem v8-03-01 and higher versions.

EMEP European ship emissions inventory

The EMEP inventory contains ship emissions for NOx, CO, SO2.

The source code is located in file GeosCore/emep_mod.f.

Please also note the following fixes:

1. Minor fixes for EMEP ship emissions
2. 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].

For more information about the data, please see the README file: GEOS_1x1/EMEP_200911/README

Bug with EMEP ship emissions for nested grids

NOTE: This update was introduced in emfossil.f in GEOS-Chem v8-02-01.

Win Trivitayanurak wrote:

This bug is in subroutine EMFOSSIL in emfossil.f. The use of function GET_EUROPE_MASK when LEMEP = .false. crashes the run because, i think, the function is not really valid when EMEP emission is not turned on. When I ran the China nested-grid, all other emission choices need to be turned off, e.g. EMEP, BRAVO. Only STREETS can be on for the China nested grid run. Therefore, w/o this fix, the run won't go anywhere.

I copy the section of the code and paste it here below. See the change in the line with !Prior to 5/1/09 (win, 5/1/09).

 !Prior to 5/1/09 (win, 5/1/09)
 !               ELSE IF ( LEMEPSHIP  .AND.
 !     $                 ( GET_EUROPE_MASK( I, J ) > 0d0 ) ) THEN
 !
 !                  ! Get SHIP EMEP emissions for NOx [molec/cm2/s]
 !                  SHIP = GET_EMEP_ANTHRO( I, J, NN, SHIP=.TRUE.)

              ELSE IF ( LEMEPSHIP ) THEN
                
                 IF ( GET_EUROPE_MASK( I, J ) > 0d0 )
                 ! Get SHIP EMEP emissions for NOx [molec/cm2/s]
    &            SHIP = GET_EMEP_ANTHRO( I, J, NN, SHIP=.TRUE.)
