AMSR-E / AMSR2 Team Leader Science Computing Facility

• Current Science Software• Science Software Updates• End of Mission Schedule• AMSR2 Team & Products


• L2A Brightness Temperatures V12 – RSS V07 delivered to TLSCF - Jan 2013– TLSCF integration

• New ISO metadata• Updated ECS metadata• Documentation• New ESDT• New Reader

– TLSCF delivered to SIPS June 2013– There were 15 files that did not include equator crossing

longitude and time in the metadata • Needed to pass QA• SIPS – GHCC (Beaumont) corrected these

Current Science Software


• L2B Ocean V07– July 2010

• Updates to accommodate LANCE processing

– Last algorithm updates • Version V05, April 2007• Improved beamfilling correction to account for different

footprint sizes of different frequencies • Include a new expression for the rain column height that

yields more accurate rain flags



• L2B Land V10– July 2010


– Last algorithm update • Version B03, June 2005• Minor modification to the soil moisture QC



• L2B Rain V11 – July 2010


– GPROF 2010 delivered to the TLSCF (L2B Rain V12)• Expecting algorithm updates soon• Integrate new L2A reader• Add ISO metadata• Update ECS metadata• New ESDT• Update documentation

• Updates to metadata to accommodate LANCE processing

– Last algorithm updates • Version V04, May 2010• RIF Filtering• Update Aral Sea filters • Include the RFI angle grid in the product



• L3 Land V07– July 2010


– Last algorithm update• Version B03, May 2005• Correct grid projection parameters



• L3 Snow V10– August 2010


– Last algorithm update• Version B05, November 2005• Update the forest cover ancillary files. • The daily product retrievals are now performed on the

AMSR-E individual Tb samples which are then averaged to the EASE-Grid 25x25 km northern and southern hemisphere projection grid.

• Retrievals are calibrated for snow depth with a snow density climatology file used to convert snow depth to snow water equivalent.



• L3 Rain V07 – April 2011

• Improved quality check on input data date

– Last algorithm update V06, April 2008• Skip duplicate (overlapping) scans in consecutive L2A files• Improve L2A Brightness Temperature binning for monthly

ocean grids• Update the leap second ancillary file to include the leap

second which occurred at the end of 2005

– Next update • Derived from L2B Rain as input (GPROF 2010)• Monthly• 0.25 degree resolution



• L3 Sea Ice V14– July 2012

• Update Southern Hemisphere sea ice mask using National Ice Center (NIC) data from June 2011

• Mask provided by NSIDC • The shoreline was developed from ENVISAT and RADARSAT

imagery from OCT 2009 until APR 2010.



• L3 Sea Ice V14– Update to the algorithm to correct internal land / ocean

flag that conflicted with the new sea ice mask – TLSCF integration in progress– New ISO metadata– Updated ECS metadata– Documentation– New ESDT– New L2A reader integration– Review by NSIDC and Science Team



• L3 Sea Ice Drift B03– Polar Stereographic grids containing speed and

direction for each hemisphere– Derived from AMSR-E 89 GHz 6.25 km resolution Tb’s– Uses the 6.25 km and 12.5 km AMSR-E sea ice products

as input– Uses a 5 day window– Browse created during product generation

• New Requirement: Java
