Here is a remarkable graphic from a new publication, Kent et al 2007, showing the distribution of SST measurements between buckets and engine inlets from 1970 on. I think that this evidence has great significance for the Folland and Parker SST adjustment, which is one of the most fundamental Team adjustments. I’ll discuss this more when I have time, but was struck by the graphic sufficiently to want to post it up immediately. I’m sure that some of you can figure out where this is going.

The known methods for air and dewpoint temperatures and pressure [(a)—(e)] are all from Pub. 47, whereas those for SST [(f)—(h)] are from Pub. 47 or ICOADS.
