In some browsers you may need to right click on the appropriate link and choose “Save Link As” to download the installer.

To install and run SeaDAS, follow the instructions on this page.

Processing Programs and Source Code

The SeaDAS data processing components are distributed separately from the SeaDAS visualization package.

To process SeaDAS OCSSW in Windows see the client/server model model. (Note: previous SeaDAS version 8.0.0 did not support Windows processing but the current SeaDAS version 8.1.0 does support Windows processing).

Currently, the processing components can only be installed on Linux or MacOSX (Intel) systems. The Linux binaries were compiled on a system with CentOS 6.10 and gcc-6.3.1. If your system is not the same, you might need to build the binaries from source.

Ensure that the requirements are satisfied

• Bash
• Python 3.6 or later
• Python requests package v2.18.0 or later

Install with GUI

Once the visualization package is installed, you can easily install the processing components:

• Select the menu item SeaDAS-OCSSW → Install/Update OC Processors

  
  
  

• 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.

1. Ensure that the requirements are satisfied:
   • Bash
   • Python
   • Git
   • cURL
2. Download the installer script and manifest script
3. Make sure the installer script is executable:

         $ chmod +x install_ocssw
         

4. Run the installer: The following will get a list of the available TAGS. Tags starting with "V" are operational versions, "T" are test versions.

   $  ./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 V2021.2 --seadas --modisa --seawifs 

   The following will install the processing source code into an existing directory:

   $   ./install_ocssw --install_dir=$HOME/ocssw --tag V2021.2 –-src 

   The following will install the programs and data packages required for MODIS direct broadcast processing:

   $   ./install_ocssw --install_dir $HOME/ocssw --tag V2021.2 --direct_broadcast

Note: this includes the processing programs and the MODIS-Aqua and MODIS-Terra data packages. It does NOT include the source code.

Command Line Configuration

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.
