Ah, found it; http://www.vision.net.au/~daly/sonde.htm shows a graph
from the fifties to nineties; assuming it's accurate, the temperature
measured by balloons has dropped nearly 1C in that time. Of course if
you cut off the ends the temperature rises rather than falls, but this
is what's so dubious about greenhouse science; you can prove anything
by choosing the right dates.
