Enhancements to this SPA include:
This SPA provides a common command and execution interface that takes advantage of a subset capability of the UW/CIMSS International MODIS/AIRS Processing Package (IMAPP). This implementation serves as a source of scientific algorithms for the following products only: Cloudmask (MOD35); Cloudtop Properties, Cloud Phase and Cloud Optical properties (MOD06); Atmospheric Profiles (MOD07); and Aerosols (MOD04 and MOD04_3K). The IMAPP_SPA functions in two modes: Standalone, or as an IPOPP plug-in.
1. Installing into an IPOPP Framework:
This SPA can be installed dynamically into an IPOPP framework to automate production of IMAPP_SPA data products. 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 the SPA. Instructions for installing an SPA and enabling its services are contained in the IPOPP User’s Guide (available on the DRL Web Portal). The SPA services for this SPA are listed in Appendix A of the User's Guide (PDF) included with this software package.
2. Download the IMAPP_3.1.1_SPA_1.4.tar.gz, IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.tar.gz (optional) and IMAPP_3.1.1_SPA_1.4_testdata.tar.gz (optional) files into the same local subdirectory.
NOTE: The optional IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.tar.gz contains coefficient files required by the MODIS Cloud Optical Properties software module (MOD06OD). This module populates the cloud optical property arrays in the MOD06 output product. In the absence of these coefficient files, the Cloud Optical Properties algorithm will not be run and the corresponding datasets in the MOD06 output product will remain unpopulated. Please refer to Step 3 should you wish to download the optional IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.tar.gz file.
3. Ensure that you have Wget installed on your system, and that you have adequate free space to accommodate the assembled IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.tar.gz file (22.5 GB). Note that you must use the same machine to both download and run the downloader_IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.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.
Download the downloader_IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.sh script to the same local subdirectory containing the IMAPP_3.1.1_SPA_1.4.tar.gz and IMAPP_3.1.1_SPA_1.4_testdata.tar.gz files. From this subdirectory, make the downloader_IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.sh script executable and run it to fully automate and verify the transfer of the IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.tar.gz file:
chmod +x downloader_IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.sh
./downloader_IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.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 IMAPP_3.1.1_SPA_1.4_MOD06OD_COEFF.tar.gz file should now be contained in the local subdirectory.
See the User's Guide (PDF) included with the software package for more details.
In order to run the package using your own input data, you can either use the 'run' scripts within the wrapper subdirectories, or modify the test scripts within the testscripts subdirectory. See the User's Guide (PDF) included with the software package for more details.
