This page describes the EDGAR v3 anthropogenic emissions, which were used in GEOS-Chem versions prior to v10-01. Much of the information on this page is now obsolete, but we will leave it here for future reference.

Overview

EDGAR v3 anthropogenic emissions were used in GEOS-Chem versions through GEOS-Chem v9-02. EDGAR v4.2 emissions (read via the HEMCO emissions component)are now the default in GEOS-Chem v10-01 and newer versions.

Anthropogenic emissions

The EDGAR emissions of NOx, CO, and SOx are the standard emissions. However, the EDGAR emissions are typically overwritten by data from various regional emissions inventories listed on our Anthropogenic emissions wiki page.

The EDGAR inventory also includes emissions from ship exhaust.

Ship emissions

For more information about the EDGAR ship emissions data files, please see the following README document: GEOS_1x1/EDGAR_200607/README

The source code routines that read the EDGAR ship emissions data from disk are:

  1. SEASCL_EDGAR_SHIP_SO2 (GeosCore/edgar_mod.F)
  2. GET_EDGAR_SHIP_SO2 (GeosCore/edgar_mod.f)

The EDGAR ship SO2 emissions are reported as per year. Routine SEASCL_EDGAR_SHIP_SO2 applies monthly scale factors (which are computed as the ratio of monthly/total ship SO2 emissions from the Corbett et al inventory to the annual EDGAR ship SO2 emissions. This is required to impose aseasonality onto the EDGAR ship SO2 emissions.
