The ESMA Project

The ESMA project is concerned with the deployment of modeling and data assimilation applications that are part of the ESMF testbed applications.

This project is hosted at: cvsacl.nccs.nasa.gov

Project admins are:

• da Silva, Arlindo
• Lucchesi, Rob
• Todling, Ricardo
• Takacs, Larry

The ESMA CVS repository

CVSACL is a version control server intended to specifically support the access control patches to CVS (https://progress.nccs.nasa.gov/trac/admin/wiki/CVSACL). Access to CVSACL requires an NCCS account (https://www.nccs.nasa.gov/). The web interface to CVS ESMA project is available at https://cvsacl.nccs.nasa.gov/cgi-bin/.

The ESMA CVS repository has a flat directory structure designed to accommodate a variety of modeling systems. The repository holds 'Applications', 'Components' and other software libraries needed to build earth modeling systems. The directories under esma/src/ are Applications/, Components/, Config/, Couplers/, Documentation/, Shared/ and of course CVS/.

PACKAGES: A collection of source files having one or more software deliverables

• Libraries
• Executables (binaries, scripts)
• Includes (.h, .mod)
• Configuration (Resource) files (.rc)
• Examples

MODULES: CVS modules are then used to compose individual modeling systems. A module is a collection of packages comprising some stand alone application, e.g. GEOSGCM_m0 (GMAO Unified Model, GEOS-5). A complete list of ESMA CVS modules is available at CVSROOT/modules.

Some examples are:

# ESMF/MAPL Tutorial
G5tutorial        -d G5tutorial/src  esma/src/Applications/G5tutorial &Config \
                                     &GEOSgcm_Shared_m2

# Ganymed
Ganymed           -d GEOSagcm &GEOSGCM_m3

etc.
