CEDS anthropogenic emissions

Overview

Global anthropogenic emissions from the Community Emissions Data System (CEDS) inventory. Emission species include aerosol (BC, OC) and aerosol precursor and reactive compounds (SO2, NOx, NH3, CH4, CO, NMVOC) and CO2. CEDS emissions are available for 1750-2014, but only 1950-2014 have been processed for implementation into GEOS-Chem v11-02f. CEDS emissions replace EDGAR as the default global anthropogenic inventory in GEOS-Chem.

For more information see the original CEDS README files:

• README-CEDS_2017-09-28.txt
• README-CEDS-VOC-speciation_2017-05-18.txt

Original data were downloaded from https://esgf-node.llnl.gov/search/input4mips/ and were processed for GEOS-Chem. The processing scripts can be found in the ExtData/HEMCO/CEDS/v2014-08/scripts subdirectory.

Previous issues that are now resolved

Add missing RCO sector to CEDS emissions entries

This fix will be included in GEOS-Chem 12.0.1.

The CEDS emissions inventory includes 8 sectors:

1. AGR: Non-combustion agricultural sector
2. ENE: Energy transformation and extraction
3. IND: Industrial combustion and processes
4. TRA: Surface Transportation (Road, Rail, Other)
5. RCO: Residential, commercial, and other
6. SLV: Solvents
7. WST: Waste disposal and handling
8. SHP: International shipping (including VOCs from oil tanker loading/leakage)

The CEDS entries in HEMCO_Config.rc implemented in v11-02f were missing lines for the RCO sector.

In addition, entries for CEDS ship emissions have also been added to the HEMCO configuration file. These emissions can be turned on/off via the CEDS_SHIP option. The option is off by default for now.
