Downloading GEOS-Chem data directories

Data Directory Access

The GEOS-Chem source code, data and meteorological field directories may be accessed by anonymous FTP from

ftp ftp.as.harvard.edu
cd pub/geos-chem

The geos-chem directory is further divided into the following subdirectories:

HDF/
data/
evaluation/
internal_releases/
mean_OH/
patches/
standard_releases/

Here is a quick look at the contents of these subdirectories:
