It should be noted that the 2009.1 MODIS ocean color products do not contain a sea surface temperature field.

The former MODIS ocean color products contained the 11-12um SST product, which was a duplicate of the data contained in the standard daytime SST product. We started doing this before we were officially tasked to produce the "standard"  MODIS SST products. The reason we discontinued the practice is that the algorithm refinement of OC and SST are on a different schedule.  There will be a reprocessing of the SST, with significant changes in algorithm coefficients and quality screening, sometime this summer.  We don't know when, exactly, because the buoy match-up analysis against collection 6 MODIS calibrated brightness temps has just started.  We don't want two different MODIS SSTs, and it would be expensive to reprocess OC again just to merge SST changes.  In addition, the SST is really not valid without the quality level info, so even if the SST algorithm was consistent, users doing Level-3 SST compositing from the OC SST product would get different results from "standard" MODIS SST products.
