- TLSCF Integration and Test Configuration

## Linux Porting

- PORTING IS COMPLETE AT THE TLSCF!
- No integration and test on MISTY (the SGI)
- Ported algorithms are not backward compatible
- Integration and test procedures have not changed
- Metadata Updates
- “Inputpointer” field now contains all input file names
- Increase the ESDT version ID
- Change the “reprocessing actual” attribute value to “reprocessed once”
- All AMSR-E ESDT descriptor files and metadata configuration files were updated for ECS version 7.21
- Maximum number of input pointers

## Linux Porting

- The AMSR-E installation program (AE_install) provided by the TLSCF to the SIPS has also been ported and integrated
- New shell script used during installation to make LF95 compilation less verbose
- Increase system stack size parameter to “unlimited”
- Accommodate syntax differences between SGI IRIX and Linux
- Differences noted in output files can be attributed to rounding

## AMSR-A

- L2A is ready to be re-sent to the SIPS-GHCC
- Due to error in processing
- L2A ESDT
- Created, tested
- Delayed due to ECS version 7.21 delivery
- Expected delivery to NSIDC by the end of the month
- L2A DAP
- Metadata and QA routines completed
- Read software changes completed

## AMSR-A

- L2A DAP (continued)
- AA_install completed
- RSS software processes either AMSR-E or AMSR-A

- AMSR-E Science Software Status

## AMSR-E Science Software Status

- L2A processing error at RSS
- Channel 89H, resolutions 1-4 from June 19, 2002 through November 4, 2004
- When resampling the 89H channel, 89V scan A was inadvertently used as input instead of 89H scan A
- SCF was notified February 28, 2008
- Affected L2A B07 and V08
- DAP V09 with the correction was delivered by the TLSCF to the SIPS March 6, 2008
- The affected data was then reprocessed at the SIPS
- To ensure the same version number for all reprocessed L2A data, the TLSCF provided software to update the unaffected L2A data to V09
- Update to metadata – external to the file as well as internal
- Files were renamed

## AMSR-E Science Software Status

- L2A processing error:  L2B and L3 impact
- Only the reprocessed data was at risk because of the time frame
- No impact to L3 products because reprocessing of L3 products had not begun
- L2B Land was the only L2B product affected
- Surface soil moisture retrieval was not affected
- Sets a QC flag if the 89H R1 is out of bounds
- Creates intermediate TB files from the resampled 89H & V R4 which are then used to create the L3 Land products
- Reprocessed with the corrected L2A

## AMSR-E Science Software Status

- L2B Land
- T08
- When no Level 2A TB’s qualify for retrieval, only a QA file is created (previously, an empty Land Level 2 files was created, causing an error during subsequent L3 processing)
- Delivered to the SIPS May 8, 2008
- T07
- First Linux version
- Byte-swapped binary ancillary files
