Overview:
===============================================================================

This directory contains Hg emissions from the GEIA and Streets inventory,
as prepared by Bess Corbitt et al (2011).  These emissions are used by the
GEOS-Chem mercury simulation.

GEIA_Streets_PRESENT_geos.1x1.nc

 -- Annual GEIA/STREETS emissions of Hg0, Hg2, Hgp, Corbitt et al 2011.

DESCRIPTION OF FILES:
---------------------

6/25/2012 E.S. Corbitt (corbitt@seas.harvard.edu)

GEIA_Streets_SCENARIO_HgX_REG.1x1.YYYY files are anthropogenic
emissions with the following specifications:

   -Based on the 1x1 gridded GEIA 2005 anthropogenic emissions inventory

   -Within major world regions (e.g. United States, Eastern Europe, etc.)
    the spatial pattern of the GEIA inventory is maintained, but a scaling
    factor is applied so that regional total emissions equal that of 
    Streets et al. 2009

  - SCENARIO may be the IPCC scenarios A1B, A2, B1, B2 or the present-day

  - HgX may be Hg0, Hg2, or HgP species emitted

  - REG or region may be one of 17 major world regions, listed below

  - YYYY is the year for the anthropogenic inventory, either 2050 for the
    future scenarios or 2006 for the present

  - See Corbitt et al. 2011 for more information, including map of regions
    in the SI

  - LIST OF REGIONS:
    CAN = Canada
    USA = United States
    CAM = Central America
    SAM = South America 
    WAF = West Africa
    EAF = East Africa
    SAF = South Africa
    NAF = North Africa
    EUR = OECD Europe
    EEU = Eastern Europe
    SOV = Former USSR
    MDE = Middle East
    SAS = South Asia
    EAS = East Asia
    SEA = Southeast Asia
    JPN = Japan
    OCE = Oceania
