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 disk servers at Harvard University (and soon at Dalhousie University).  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]].

== HEMCO data directory structure ==
 
The sections below describe each of the data sets contained in the HEMCO directory tree, grouped by type. 
 
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 '''Status''' column describes the current status of each data set:
 
:{| 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.
 
NOTE: The inventories are grouped and listed in the same order as in the <tt>HEMCO_Config.rc</tt> version that ships with [[GEOS-Chem 13.0.0]].

NOTES about ship emissions:
== Emissions reference ==
#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.

To obtain the hemco_data_download package, use Git to clone this repository
 
<nowiki>git clone https://github.com/GCST/hemco_data_download.git</nowiki>
 
This will create a directory named <tt>hemco_data_download</tt>, in which you should see the following files:

=== Setting up the configuration file ===

<span style="color:red">'''''The hemco_data_download package will be retired in GEOS-Chem 12.7.0 in favor of the [[Downloading data with the GEOS-Chem dry-run option|GEOS-Chem dry run option]].'''''</span>
 
The configuration files (i.e. <tt>hemcoDataDownload.rc</tt> and <tt>forTesting.rc</tt>) are pretty much self-explanatory. 
 
At the top of the configuration file you will see this section:
 
###############################################################################
#                                                                            #
#  Specify the remote and local HEMCO data paths, plus other options.        #

|-valign="top"

|Location on the FTP server from which you are going to download the data. This can be from either Harvard or from Dalhousie. (For now we will use the Harvard server). You can edit this accordingly.
 
|-valign="top"
|<tt>Your HEMCO data path</tt>
|The root-level directory for HEMCO data on your own disk space. If you are not sure where to place this, then ask your sysadmin.
 
|-valign="top"
|<tt>Verbose output</tt>
|Lets you specify if you want to print out extra output during the download process. This can be set to either "yes" or "no".
 
|-valign="top"
|<tt>Dryrun only</tt>
|Allows you to print out the data download commands without actually downloading the data. This is useful for debugging.  This can be set to either "yes" or "no".

In the next section you specify all of the HEMCO inventories that you want to download. You will see this header:
 
###############################################################################

#                                                                            #
#  These data directories comprise the recommended emissions configuration    #
#  for typical GEOS-Chem full-chemistry and specialty simulations.            #
#                                                                            #
#  NOTE: In most cases, you only have to specify the top-level folder.        #
#  All subfolders will be downloaded automatically.                          #
#                                                                            #

... etc ...
Each line specifies the name of a HEMCO emissions inventory and the data path where it can be found on disk, relative to the root data path.  NOTE: The script will replace the <tt>$ROOT</tt> token with the value you gave to the "HEMCO remote data path" above.  (Lines starting with the comment character # will be ignored.)
 
Any inventory found in this section will be downloaded. To prevent an inventory from being downloaded you can either comment it out (i.e. place a # in the first column) or move the inventory to the next section.
 
The final section specifies HEMCO emission inventories that you do not wish to download. The section looks like this:
 
###############################################################################
#                                                                            #

#  are not used in typical GEOS-Chem simulations.  If you wish to download    #
#  any of these inventories, simply move the corresponding entry for each    #
#  inventory to the previous section.                                        #

Once you have [[#Setting up the configuration file|set up your configuration file]], you can run the <tt>hemcoDataDownload.pl</tt> script to start downloading the HEMCO data to your local server.  To run the script you can type:
 
hemcoDataDownload.pl
 
If you do not specify a configuration file name, then the <tt>hemcoDataDownload.pl</tt> scriptwill read the default configuration file <tt>hemcoDataDownload.rc</tt> configuration file.  If you wish to specify a different configuration file name, simply pass that as an argument to the script, e.g.
 
hemcoDataDownload.pl myNewConfigFile.rc
 
Before you start downloading GB's of data, we recommend that you run a short test to make sure that the data directories are being copied to the proper locations on your disk server.  For this purpose, we have provided a configuration file named <tt>forTesting.rc</tt>.  Typing
 
hemcoDataDownload.pl forTesting.pl
 
will only download a couple of data inventories that do not take up much disk space. This allows you to ensure that the data transfer is sucessful without making you wait a long time.

== 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:
 
#''[[Preparing data files for use with HEMCO|''Preparing data files for use with HEMCO]]''
#''[[Submitting updates for inclusion in GEOS-Chem]]''

Latest revision as of 21:17, 30 March 2023

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
GEOS-Chem 13.4.0 ChemistryInputs.csv EmissionInputs.csv InitialConditions.csv
GEOS-Chem 13.3.0 ChemistryInputs.csv EmissionInputs.csv InitialConditions.csv
GEOS-Chem 13.2.0 ChemistryInputs.csv EmissionInputs.csv InitialConditions.csv
GEOS-Chem 13.1.0 ChemistryInputs.csv EmissionInputs.csv InitialConditions.csv
GEOS-Chem 13.0.0 ChemistryInputs.csv EmissionInputs.csv InitialConditions.csv
