International MODIS/AIRS Processing Package

 IMAPP Virtual Appliance v2.0 release                  23 April 2015

The IMAPP Virtual Appliance is a complete processing system for MODIS data acquired by direct broadcast from the Terra and Aqua spacecraft. It is implemented in the form of a VMware virtual machine that is easy to install and run on platforms including

- Microsoft Windows 64-bit (7, Vista, XP),
- Intel Linux (Red Hat, CentOS, Ubuntu; 2.6 kernel or higher),
- Apple OS X (10.6 or higher).

The minimum requirements to run the IMAPP Virtual Appliance are

(1) VMware Player (a free download for Windows and Linux), or VMware Fusion for OS X,
(2) 2 CPUs, 4 GB of RAM, and a minimum of 50GB of disk space.

Please note: With the inclusion of updated software and coefficient files, the size of the VM is now about 7 GB.

New Features in Version 2.0
  • MODIS Level 1 processing software through NASA OBPG SeaDAS version 7.0.2.
  • MODIS Atmosphere processing software updated to IMAPP MODIS Level 2 Version 3.1 (NASA baselined Collect 6 software).
  • MODIS Ocean processing software updated to the current NASA OBPG SeaDAS version.
  • Linux guest is updated to Lubuntu 14.04.1 Desktop LTS (64-bit).
  • Updated Desktop 1280 x 768 to match modern monitor resolution and aspect ratio.
  • The software no longer supports AIRS and AMSR-E instrument processing.
Features of the IMAPP Virtual Appliance
  • Can be installed, configured, and be ready to start processing data within 30 minutes of completing download.
  • Designed to be easy to modify, maintain, and upgrade.
  • Preconfigured with MODIS Level 1 and IMAPP Atmosphere software installed and ready to run.
  • Other DB processing packages can be added (or removed) by editing one configuration file, and then running an installer script.
  • Highly reliable and fault tolerant, and is fast and efficient on modest computer hardware.
  • Supports automated ingest and processing of Level-0 PDS files from a local directory or a remote anonymous FTP site.
  • Implemented entirely in bash scripts (<3000 lines). All bash scripts are extensively commented, and are designed to make it easy to add your own local DB processing software.
  • Uses only freely available software, and is licensed under the terms of the GNU GPL.
