Getting Started

Getting Started with CRTM

There are three levels to get started with the CRTM, depending your application and interests:

Beginner (CRTM Bundle Using a JEDI container):

• First, you'll need to follow the directions here: Installing Singularity
• Once you have the singularity environment installed (either here or as part of a JEDI installation), clone and download the CRTM bundle https://github.com/JCSDA/crtm-bundle
• Inside the singularity environment:

git clone https://github.com/JCSDA/crtm-bundle
cd crtm-bundle/
sh ./kickstart_pycrtm.sh  

     This handy script will download, build, compile the CRTM, and link to the pyCRTM repository.

Intermediate: (CRTM Using a Container)

• Follow the Singularity instructions above.
• Clone and download CRTM v2.4.0 repository to a Linux machine, inside your container, and follow the included README_JEDI.md
• git clone --branch=v2.4.0 https://github.com/JCSDA/crtm
• cd crtm
• The README_JEDI.md contains a wealth of information on building and compiling in a container environment.

Advanced: (CRTM in a non-container build)

• Clone and download CRTM v2.4.0 repository to a Linux machine, and follow the included README.md
• git clone --branch=v2.4.0 https://github.com/JCSDA/crtm (remove --branch=v2.4.0 to get the latest master release)
• cd crtm
• Build using the traditional autotools approach. The README.md contains the directions for this.
