Page 3 GHRSST-PP, 8 th Science Team Meeting, Melbourne, 16 th May 2007 Notes  Scheme does not use comparisons to minimum SST climatology  Scheme does not use all levels (0 to 5) Does it have to?  SSES will still use static biases (and standard deviation) Will be updated later this year  Improved SSES following completion of (A)RC Project Do we give error in AATSR SST or comparison to in situ?
