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.

== HEMCO data directory structure ==
 
The sections below describe each of the data sets contained in the HEMCO directory tree, grouped by type.  Each data set is contained in a subdirectory of the HEMCO root directory, which is specified by the <tt>$ROOT</tt> token.  (For example, on the Harvard disk server, <tt>$ROOT</tt> points to the directory <tt>/mnt/gcgrid/data/ExtData/HEMCO/</tt>.)
 
The status column in the tables below denote the following:
 
{| border=1 cellspacing=0 cellpadding=5

If use GEOS-Chem, then we recommend that you download the data sets that are listed as CURRENTLY USED, 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.

== Data directories by GEOS-Chem version ==


=== Non-emissions data ===
Our [https://github.com/geoschem/input-data-catalogs/ '''input-data-catalogs'''] Github repository contains lists of input files needed to run GEOS-Chem simulations.  These are contained in the comma-separated files <tt>ChemistryInputs.csv</tt>, <tt>EmissionInputs.csv</tt> and <tt>InitialConditions.csv</tt>, and  [https://github.com/geoschem/input-data-catalogs/blob/main/MeteorologicalInputs.csv <tt>MeteorologicalInputs.csv</tt>]. 


The following subdirectories of the HEMCO directory tree input data contains non-emissions data sets.  Most of these are used as inputs to GEOS-Chem's chemistry modules (i.e. photolysis, stratospheric chemistry, etc.).
Passing any of these files as input to the [https://github.com/LiamBindle/bashdatacatalog/wiki '''bashdatacatalog'''] utility will initiate a data transfer to your local disk storage.

== Emissions reference ==
 
== Downloading the HEMCO data directories ==
 
The [[GEOS-Chem Support Team]] has created a package called [https://github.com/GCST/hemco_data_download '''hemco_data_download'''].  With this package, you can download the various emissions inventories and related data files for HEMCO to your own disk server.  Furthermore, you can specify which data directories that you would like to download (as well as those you would like to ignore) via a configuration file.
 
=== Obtaining the hemco_data_download package ===
 
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:
 
;<tt>README</tt> : File with an overall description of the directory contents
;<tt>hemcoDataDownload.pl</tt> : Perl script to download HEMCO data directories
;<tt>hemcoDataDownload.rc</tt> : Configuration file for the <tt>hemcoDataDownload.pl</tt> script.  In this file you can specify which HEMCO data directories you would like to download and which you would like to omit.
;<tt>forTesting.rc</tt> : A configuration file that you can use for testing or debugging. This will tell <tt>hemcoDataDownload.pl</tt> only to download a couple of emissions inventories with files that do not take up much disk space.
 
--[[User:Bmy|Bob Y.]] 13:58, 12 February 2015 (EST)
 
=== Setting up the configuration file ===
 
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.        #
#                                                                            #
###############################################################################
<nowiki>Remote HEMCO data path | ftp://ftp.as.harvard.edu/gcgrid/data/ExtData/HEMCO</nowiki>
Your HEMCO data path  | /as/scratch/bmy/HEMCO
Verbose output        | yes
Dryrun only?          | no
 
#'''Remote HEMCO data path''' is the 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.
#'''Your HEMCO data path''' specifies 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.
#'''Verbose output''' lets you specify if you want to print out extra output during the download process. This can be set to either "yes" or "no".
#'''Dryrun only''' flag allows you to print out the data download commands without actually downloading the data. This is useful for debugging.
 
In the next section you specify all of the HEMCO inventories that you want to download. You will see this header:

=== Downloading the data ===
 
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 our [[Preparing data files for use with HEMCO|''Preparing data files for use with HEMCO'' wiki page]] 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
GEOS-Chem 13.4.0 ChemistryInputs.csv EmissionInputs.csv InitialConditions.csv
