Background

• Current processing
• Collect and process MODIS oceans data from TERRA
  and AQUA in real time.
• RT-STPS, Simulcast, GBAD, SeaDAS
• Data available online or by subscription

Is there life after MODIS?

• TERRA MODIS is already past its life expectancy,
  and has limited processing support
• AQUA MODIS is nearing retirement age
• VIIRS (Visible Infrared Imager/Radiometer Suite)
• next U.S. satellite sensor to continue oceans
  monitoring
• scheduled for launch on NPP in 2009?
• followed by NPOESS in 2013?
• we need to prepare for the transition!

IPOPP alpha test program

• IPOPP International Polar Orbiter Processing
  Package (NASA GSFC DRL)
• Software to process MODIS (and future NPP) data
  in real time.
• Alpha Test Program
• Provides IPOPP and related software to several
  direct broadcast stations for evaluation.

• Alpha stations
• USDA Forest Service Remote Sensing and
  Applications Center (USA)
• Oregon State University (USA)
• University of South Florida (USA)
• National Institute for Space Research (Brazil)
• National Commission for Biodiversity of Mexico

Why IPOPP rocks!
1. Startup
Easy to run One command starts all the programs
running (runs continuously). Whenever a new PDS
(Level 0) file appears, the processing
starts. Easy to configure Which algorithms are
run can be chosen from a single config
file. More (custom) algorithms can be
added. Comprehensive documents.

2. Running
Easy to monitor A log interface shows real-time
log output and a history. The logs are
searchable and can be viewed on any
x-terminal. Easy to manually run a pass (for
testing or reprocessing) To run from PDS,
simply place it in the right folder. To rerun a
processed file, an interface lets you select the
file to redo.

3. Output
Provides output you hope for HDF files TIFF
images XML files (with pass information) Produces
all data types with no extra work! air we
have plenty of clouds! land fires are common
in summer ocean still our
favorite
22
Evaluation Plans

• Memorize all the acronyms.
• Track down what is causing the remaining
  differences between the SeaDAS and IPOPP output.
• Test reprocessing capabilities.
• Investigate software update ease.
• Provide suggestions to improve log interface and
  access.
• Modify our system to include MODIS FLH as an
  output product.
• Try adding a custom SPA.
• Have a spa.

Next weeks agenda
Dish disassembly in June 2005after water
intrusion. Well be repeating this next week to
fix a new mechanical problem.
