Installation

1. Provide a convenient empty local subdirectory to contain the software package. Ensure that you have Wget installed on your system, and that you have adequate free space to accommodate the assembled file [OMPSNADIR_2.7.1_SPA_2.1.tar.gz (13.5 GB)]. Note that you must use the same machine to both download and run the downloader_OMPSNADIR_2.7.1_SPA_2.1.sh script. The script must be run to completion within 24 hours after it was downloaded, or it will be necessary to download and run a fresh script.

2. Download the downloader_OMPSNADIR_2.7.1_SPA_2.1.sh script to the local subdirectory. From the local subdirectory, make the downloader_OMPSNADIR_2.7.1_SPA_2.1.sh script executable and run it to fully automate and verify the transfer of the complete OMPSNADIR_2.7.1_SPA_2.1 package.

chmod +x downloader_OMPSNADIR_2.7.1_SPA_2.1.sh
./downloader_OMPSNADIR_2.7.1_SPA_2.1.sh

Progress indicators will appear as the package is downloaded, assembled and verified. When the entire process is complete the script will return the message "File successfully downloaded." The OMPSNADIR_2.7.1_SPA_2.1.tar.gz and OMPSNADIR_2.7.1_SPA_2.1.pdf files should now be contained in the local subdirectory. The download is complete.

Installing into an IPOPP Framework:

This SPA must be installed dynamically into an IPOPP framework to automate production of OMPSNadir data products. IPOPP v5.0 with Patch 1 or higher must be installed to run this SPA.

The SPA installation process will install SPA service(s) into IPOPP. An SPA service is an IPOPP agent that provides the mechanism necessary for running an SPA automatically within the IPOPP framework. Once this SPA is installed, users must enable the service(s) corresponding to this SPA along with any other prerequisite service(s). Instructions for installing an SPA and enabling its services are contained in the IPOPP User's Guide (available on the DRL Web Portal).

Run

Please refer to the the User Guide (PDF) included with the software package for details.
