One thing that I was thinking is that the Menne et al (Menne and Vose?) USHCN adjustments altered the sign of the US trend in Tmax and Tmin in some regions. [Gilbert Compo to Phil Jones]
One final thing - don't worry too much about the 1940-60 period, as I think we'll be changing the SSTs there for 1945-60 and with more digitized data for 1940-45.
