Wood for Trees maintains copies of all the major climate data from satellite systems and surface records. NASA, Hadcrut, UHI, they are all there.

If you want to compare January temperature trends in the northern hemisphere as recorded by NASA to July temperatures as recorded by Hadcrut (no idea why you would do that, its just an example) for the last 100 years, you can

What caught my eye is that south polar is showing a negative trend. AR4 WG1 projects a warming trend for south polar about double that of temperate and tropics!
Belay my last comment. Just went to the report and double checked, my recollection was faulty. South Polar is slightly less than tropics and temperates:
