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

Data Directory Structure

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:


Directory Description
/data Root Data Directory
/data/GEOS_1x1 1x1 global grid emissions etc. files
data/GEOS_1x1_CH 1x1 China-nested grid emissions etc files
/data/GEOS_1x1_CH/GEOS_3 1x1 China-nested grid GEOS-3 met fields
/data/GEOS_1x1_NA/ 1x1 NA-nested grid emissions etc files
/data/GEOS_1x1_NA/GEOS_3 1x1 NA-nested grid GEOS-3 met fields
   
/data/GEOS_2x2.5/ 2x2.5 emissions and other data files
/data/GEOS_2x2.5/GEOS_1/YYYY/MM GEOS-1 2x2.5 met data
