This repository has input data catalogs for GEOS-Chem. The catalog files are intended for downloading GEOS-Chem input data with the bashdatacatalog. You can to obtain input data according to
- the GEOS-Chem versions you use (e.g., 13.2 + 13.4)
- the meteorology you use (e.g., MERRA2 2x2.5 + GEOS-FP 0.25x0.3125 NA nested)
- time spans of your simulation (e.g., 2019-01-01 to 2020-01-01)
NOTE: You do not need to clone this repository. You can download data catalogs from here.
Create a directory called MyCatalogs/ in the top-level of your GEOS-Chem input data directory (the directory that has HEMCO/, CHEM_INPUTS/, etc. ).
This directory is where you will put the catalog files you are actively using.
liam:~$ cd /ExtData
liam:/ExtData$ mkdir MyCatalogsNext, download the data catalogs for the GEOS-Chem versions you use from here: http://geoschemdata.wustl.edu/ExtData/DataCatalogs/. For example,
I am going to use 13.2 and 13.4 so I am going to download the catalog files to MyCatalogs/13.2 and MyCatalogs/13.4. Meteorological inputs do not change
between GEOS-Chem versions so you can put MeteorologicalInputs.csv at MyCatalogs/MeteorologicalInputs.csv. Here is what MyCatalogs/` looks like after
downloading the catalog files.
liam:/ExtData$ tree MyCatalogs
MyCatalogs
├── 13.2
│ ├── ChemistryInputs.csv
│ ├── EmissionsInputs.csv
│ └── InitialConditions.csv
├── 13.4
│ ├── ChemistryInputs.csv
│ ├── EmissionsInputs.csv
│ └── InitialConditions.csv
└── MeteorologicalInputs.csv
Next, edit MeteorologicalInputs.csv so that the meteorological data collections you use are enabled (i.e., set column 3 to 1 for every collection you need,
and set it to 0 for collections you do not use).
Now you can run bashdatacatalog commands like
liam:/ExtData$ bashdatacatalog MyCatalogs/**/*.csv list-missing url 2019-01-01 2020-01-01 NOTE: You should always run bashdatacatalog from the top-level of input data repository (i.e., /ExtData in my case).
When a collection is added/removed - Make the appropriate changes to the catalog files on the dev branch.
When a new version of GEOS-Chem is released - Tag dev with the new GEOS-Chem version number.
