## 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.

-  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 (Mexico)
-  Center for Rapid Environmental Assessment and Terrain Evaluation (USA)
-  Landgate Satellite Remote Sensing Services (Australia)

## IPOPP vs. SeaDAS

- MODIS chlor-a: March 10, 2008
- (southern portion of a pass)

- IPOPP

- SeaDAS

## IPOPP vs. SeaDAS

- IPOPP MODIS chlor-a March 10, 2008

- MODIS chlor-a difference (mg m-3)
- IPOPP – SeaDAS

- 5

- -5

- 0

- These differences were caused by using different ancillary files (OZONE, MET, OISST).

## IPOPP vs. SeaDAS

- Histogram of the difference between IPOPP and SeaDAS chlor-a for MODIS from the Baja California region on March 10, 2008
- using different ancillary files

- IPOPP – SeaDAS

## IPOPP vs. SeaDAS

- IPOPP MODIS chlor-a March 10, 2008

- MODIS chlor-a difference (mg m-3)
- IPOPP – SeaDAS

- 0.001

- -0.001

- 0

- These used the same ancillary files (OZONE, MET, OISST).

## Why IPOPP rocks!

- 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.

- 1. Startup

## Why IPOPP rocks!

- 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.

- 2. Running

## Why IPOPP rocks!

- 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

- 3. Output

## 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 week’s agenda

- Dish disassembly in June 2005after water intrusion.
- We’ll be repeating this next week to fix
- a new mechanical problem.
