- Select desired options and click Run*
- Once installed, the processing components can be updated when necessary by repeating the above steps.
Manual Installation
The processing components can be installed manually, with or without the installation of the visualization package.
- Ensure the requirements detailed on the SeaDAS "requirements" tab are satisfied:
- Download the installer script and manifest script.
Make sure the installer script is executable:
$ chmod +x install_ocssw
Run the installer:
The following will get a list of the available Tags. Tags starting with "V" indicate operational versions while tags starting with "T" indicate test versions. The latest release is OCSSW V2025.5 tag.
$ ./install_ocssw --list_tags
The following will install the processing programs and required data packages for the MODIS-Aqua and SeaWiFS missions into the ocssw directory in the user's HOME directory:
$ ./install_ocssw --install_dir $HOME/ocssw --tag {latest-tag} --seadas --modisa --seawifs The following will install the processing source code into an existing directory:
$ ./install_ocssw --install_dir=$HOME/ocssw --tag {latest-tag} –-src The following will install the programs and data packages required for MODIS direct broadcast processing:
$ ./install_ocssw --install_dir $HOME/ocssw --tag {latest-tag} --direct_broadcast
Note: this includes the processing programs and the MODIS-Aqua and MODIS-Terra data packages. It does not include the source code.

Add the following lines to your .bashrc file to configure your command line environment. This assumes your login shell is bash. If you are using a different shell, talk to your system admin.
export OCSSWROOT=[SeaDAS_install_dir]/ocssw
source $OCSSWROOT/OCSSW_bash.env
where: SeaDAS_install_dir is the directory where you installed SeaDAS.
