HEMCO data directories

NOTE: Page under construction

HEMCO data directory structure

In the following sections we list the directory structure containing emissions inventories and related data files for use with HEMCO. Each data directory is referenced relative to the HEMCO root directory, which is specified by $ROOT token.

For example, on the Harvard disk server, the value of $ROOT is /mnt/gcgrid/data/ExtData/HEMCO/. All of the data files read by HEMCO are stored in subfolders of this root directory.

Downloading the HEMCO data directories

The GEOS-Chem Support Team has created a package called 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

git clone https://github.com/GCST/hemco_data_download.git

This will create a directory named hemco_data_download, in which you should see the following files:

README

File with an overall description of the directory contents

hemcoDataDownload.pl

Perl script to download HEMCO data directories

hemcoDataDownload.rc

Configuration file for the hemcoDataDownload.pl script. In this file you can specify which HEMCO data directories you would like to download and which you would like to omit.

forTesting.rc

A configuration file that you can use for testing or debugging. This will tell hemcoDataDownload.pl only to download a couple of emissions inventories with files that do not take up much disk space.

Setting up the configuration file

The configuration files (i.e. hemcoDataDownload.rc and forTesting.rc) are pretty much self-explanatory. At the top of the file you will see this section:

###############################################################################
#                                                                             #
#  Specify the remote and local HEMCO data paths, plus other options.         #
#                                                                             #
###############################################################################

Remote HEMCO data path | ftp://ftp.as.harvard.edu/gcgrid/data/ExtData/HEMCO
Your HEMCO data path   | /as/scratch/bmy/HEMCO
Verbose output         | yes
Dryrun only?           | no

1. 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.
2. 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.
3. 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".
4. 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:

#  THE FOLLOWING DATA DIRECTORIES WILL BE DOWNLOADED.                         #

#  These data directories comprise the recommended emissions configuration    #
#  for typical GEOS-Chem full-chemistry and specialty simulations.            #
#                                                                             #

... etc ...

Lines starting with the comment character # will be ignored. 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 $ROOT token with the value you gave to the "HEMCO remote data path" above.

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

1. 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:

###############################################################################

Downloading the data

Once you have set up your configuration file, you can run the hemcoDataDownload.pl script to start downloading the HEMCO data to your local server. To run the script you can type:

hemcoDataDownload.pl

which will read the default hemcoDataDownload.rc configuration file.

You may also specify a different configuration file name as an argument to the script. For example, we have provided a configuration file named forTesting.rc that you can use to test if the data is being downloaded to the right directory path. 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.
