On this page we describe the directory tree from which the [[HEMCO|HEMCO emissions component]] can read emissions inventories and other atmospheric data sets.
== Overview ==
== Overview ==


The [[HEMCO|HEMCO emissions component]] can read several types of emission inventories, as well as other types atmospheric data sets, such as production and loss rates, or concentration data.  We have collated all of this data into a comprehensive directory tree structure.  Each folder of the HEMCO data directory tree represents a particular emissions inventory or other data set.
On this page, we provide lists of data (chemistry inputs, emissions, initial conditions, and meteorology) that are read into GEOS-Chem by the [https://hemco.readthedocs.io Harmonized Emissions Component (HEMCO)].  These data reside at [http://geoschemdata.wustl.edu '''geoschemdata.wustl.edu'''] and at the '''s3://gcgrid''' Amazon S3 bucket.
 
At present, the HEMCO data directory tree resides on the Compute Canada and AWS s3://gcgrid bucket.  We have created a package that will let you download this directory tree to your local disk storage space.  For more information, please see the [[#Downloading_the_HEMCO_data_directories|''Downloading the HEMCO data directories'']] section below.
 
Please see [[Emissions_and_Deposition_Working_Group#Recommended_Default_Emission_Inventories|our list of recommended default emission inventories]], which has been compiled by the [[Emissions and Deposition Working Group]].
 
== Downloading the HEMCO data directories ==
 
We recommend the following methods for downloading the HEMCO data directories, depending on which GEOS-Chem version you are using:

== HEMCO data directories corresponding to an emissions option ==
 
The sections below describe each of the data directories corresponding to a HEMCO inventory or extension.  These are grouped in the order in which they appear in the <tt>HEMCO_Config.rc</tt> version that ships with [[GEOS-Chem 13.0.0]].''
 
In each of the tables below:
 
:The '''Inventory''' column contains a link that describes each data set in more detail.  Most of these links point to existing pages on the GEOS-Chem wiki.
 
:The '''Data file info''' column points to the README files that are stored with each data set.  Each README provides a list of the files contained within a given folder, information about the data contained in each file, and (often) a description of how the files were created.
 
:The '''Path''' column shows the location of each data set, with respect to <tt>$ROOT</tt>, the top-level HEMCO directory.  For example, on the Harvard disk server, <tt>$ROOT</tt> points to the directory <tt>/mnt/gcgrid/data/ExtData/HEMCO/</tt>.
 
:The '''Default or optional?''' column contains this description
 
:{| border=1 cellspacing=0 cellpadding=5
|-valign="top"
|width="225px" bgcolor="#00FF00"|'''DEFAULT SETTING'''
|width="785px"|Denotes that the data set is part of the standard emissions configuration for GEOS-Chem, that is:
*It is used in the GEOS-Chem 1-month and 1-year full-chemistry [http://acmg.seas.harvard.edu/geos/geos_benchmark.html benchmark simulations], or
*It is used in one or more of the [[GEOS-Chem_chemistry_mechanisms#Specialty_simulations|GEOS-Chem specialty simulations]].

:If use GEOS-Chem, then we recommend that you download the data sets that are listed as '''DEFAULT SETTING''', as these form the standard GEOS-Chem emissions configuration.  You are free, however, to use any of the data sets listed below.  Your choice of data sets will depend on your particular research needs.

NOTES about ship emissions:
#CEDS ship emissions are the default ship inventory in [[GEOS-Chem 12#12.1.0|GEOS-Chem 12.1.0]] and later versions.
#*Data files for CEDS ship emissions are stored with the other CEDS emission sector files in the HEMCO data path: <tt>$ROOT/CEDS/v2018-04/</tt>.
#If CEDS emissions are turned off above then:
#*ARCTAS should be used over ICOADS, CORBETT, and HTAP for SO2
#*ICOADS should be used for CO and NO.
#The NEI2011 ship emissions data only extends a few km from land.  They are therefore coastal emissions inventories and not global emissions inventories.

== Submitting new data for use with HEMCO ==
 
If you have a new emissions inventory or other atmospheric data set that you would like to add to the HEMCO data directories, then please contact the [[GEOS-Chem Support Team]].  Data files must be in COARDS-compliant or CF-compliant netCDF format.  Please see the following pages for more information:

Overview

On this page, we provide lists of data (chemistry inputs, emissions, initial conditions, and meteorology) that are read into GEOS-Chem by the Harmonized Emissions Component (HEMCO). These data reside at geoschemdata.wustl.edu and at the s3://gcgrid Amazon S3 bucket.

Data directories by GEOS-Chem version

Our input-data-catalogs Github repository contains lists of input files needed to run GEOS-Chem simulations. These are contained in the comma-separated files ChemistryInputs.csv, EmissionInputs.csv and InitialConditions.csv, and MeteorologicalInputs.csv.

Passing any of these files as input to the bashdatacatalog utility will initiate a data transfer to your local disk storage.

Version Chemistry Inputs Emissions Inputs Initial Conditions
GEOS-Chem 14.1.1 ChemistryInputs.csv EmissionInputs.csv InitialConditions.csv
GEOS-Chem 14.1.0 ChemistryInputs.csv EmissionInputs.csv InitialConditions.csv
GEOS-Chem 14.0.0 ChemistryInputs.csv EmissionInputs.csv InitialConditions.csv
