lol, i think it's been done. At least, there's a specific rule that forbids it, which usually means that someone tried it!

*In theory only since I've never heard of this being done*
I'd guess that both temperature and atmosphere pressure would only be relevant for air density. ... and that SPL meters would measure the difference between peaks and lows and therefore not be much affected by ambient air pressure. What would be strongly affected would be tuning since the weight of the air at various densities would affect port calculations. ... and of course a change in tuning would either increase or decrease SPL depending on how well it matched the tone being played.
... allowing for possibilities like a cab full of either CO2 or Helium could result in making smaller boxes yield good results. No idea which way you'd need to go to do that.
*open for any input on that*
 OK, so I just remembered that cold also affects mechanical compliance of things like surrounds, plastics and vinyl Car seats as well. So, do people tend to get better numbers in cold weather?
Sometimes, when I'm really nervous, I stick my hands in my armpits, and I smell them. *SSSSNNNNNNNNNHHHHHHHHHHHH*. SupahStahh!

oh some guy in a 1/2 bagged cougar said his sh*t was the loudest in town and he was running in the 1800+ rms class at a show here in town. He hit like 145 on the meter. My buddy pulls up to the meter in a lifted Cherokee w/3 CVX 12s and a 1500.1 kicker and hits 149.2. I was laughing at the guy(mainly because he only had the front of his car bagged)what a douche
