My bad..

When checking for the tropopause, i.e.

Code:

if ( height < tropopause ) then
else
end

We have to adjust the whole T_std equation, not the the TLR!

Note I had this

Code:

if ( height < tropopause ) then
   TLR = 6.49(°C/1,000m) = 1.98(°C/1,000ft) = 3.56(°F)/1,000ft
else
   TLR = -56.5(°C) = 216.65(°K)

Which is wrong!

What we want to do is this

Code:

if ( height < tropopause ) then
   T_std = T_o - Alt_ind × TLR
else
   T_std = T_tropopause

Where

Code:

T_Topopause = -56.5(°C) = 216.65(°K)
