Skin and Bulk Sea Surface Temperature Estimates from Passive Microwave and Thermal Infrared Satellite Imagery and their Relationships to Atmospheric Forcing, S. Castro, B. Emery, G. Wick, IGARSS 2004
Additional regional biases in TMI investigated: land contamination flag added, increase in STD when near land, and regional biases studied – related to stability of boundary layer, (water vapor, air temperature)
4) AVHRR biases/STD calculated as a function of time of observation, month, channel differences, side of scan, latitude, scan angle
5) Report on estimation of errors due to aerosols: type of aerosol important
Report for JCSDA project on use of NAAPS Product for reducing aerosol-induced bias in AVHRR SST retrievals, A. Harris, NOAA-CICS, University of Maryland
Figure 3. Linear dependencies of ∂Ti/∂Χ on total clear-sky (i.e. no aerosol) transmittance, simulated for desert aerosol.
Fortran code with initial diurnal model supplied to MISST team, continuing development & reformulation scheduled for June.

CIRIMS skin radiometer compared to bulk temperature for a number of cruises. Clear dependence on wind speed similar to Donlon 2002 paper. Results indicate skin-bulk differences estimated well by wind speed model.

FNMOC-Stennis now updates bias/STD daily. In operational data stream. Has added AOD for possible aerosol correction.
Data pushed to FNMOC and JPL in NRT
Initial testing completed
FR-MMR file created for each L2P file
L2P TMI – coming soon!
Update to SSES, diurnal model, formatting, additional meta-data: June 05
