MODIS Sea Surface Temperatures Robert H. Evans Peter J. Minnett Meteorology Physical Oceanography Rosenstiel School of Marine and Atmospheric Science University of Miami Miami MODIS SST update Latitude Band – seasonal offsets, correction approach to use separate SST retrieval coefficients per lat band. SST4 not affected. SST coverage – current quality tests can results in loss of SST in high gradient regions, GS core – correction approach to test only for ‘too cold’. Test with OGBP last week shows revised test successful. TERRA mirror side offset – requires revised mirror side bias correction Worked with OBPG to correct coding errors Transfer match-up extraction SST AQUA SST4 TERRA SST TERRA SST4 AQUA TERRA Match-ups vs timeby latitude band SST4 residuals (left)and in situ data density (right) Improved SST outlier testing GS core, slope-stream boundary Terra mirror side correction SST CDRs – traceability to NIST standards Climate Data Records require traceability to National Standards. For MODIS SSTs this is through the Infrared Radiometry Calibration Facilities at RSMAS. The RSMAS Water Bath Black-Body Calibration Target was characterized by the NIST EOS Transfer Radiometer (TXR) during a workshop in 2001, at the start of the Terra, Aqua and Envisat Missions NIST traceability to MODIS SSTs through M-AERIs and ISARs Follow-up workshop planned for late 2008. M-AERI ISAR deployments M-AERI deployments on Explorer of the Seas halted on 1 Dec 2007; new operating framework being negotiated. M-AERIs continue to be deployed on Research Vessels, one currently on Ronald H Brown, another to be installed on Oden next month. ISAR deployed on Jingu Maru on a trans-Pacific route.
