Adiabatic lapse rate

Does the lapse rate equation hold in all cases? I was recently
wondering what kind of temperature would be reached at 35 Kft
over Arctic Canada in January. It seemed that the lapse rate
equation would lead you to expect temperatures that would be
causing nitrogen and carbon dioxide to be condensing which
doesn't seem likely.


The equation breaks at tropopause, and
your requested altitude is quite near it,
if not above.

AFAIK, you need measurements for the
temperature, as the equation cannot handle it.
