The University of Wisconsin-Madison team is pleased to announce the release of the NASA International MODIS/AIRS Processing Package (IMAPP) Virtual Appliance for the processing of direct broadcast MODIS data. It is available for download via the IMAPP website at:

http://cimss.ssec.wisc.edu/imapp/

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 64-bit (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 NASA OBPG SeaDAS version 7.1.
  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.
