{ %%%%%% Algorithm name %%%%%%
temp\_static\_cnrm
}
{ %%%%%% Algorithm summary %%%%%%
Calculates static temperature of the air from total temperature.  
This method applies to probe types such as the Rosemount.
}
{ %%%%%% Category %%%%%%
Thermodynamics
}
{ %%%%%% Inputs %%%%%%
$T_t$ &	Vector & Measured total temperature [K] \\
${\Delta}P$ & Vector & Dynamic pressure [hPa] \\
$P_s$ & Vector & Static pressure [hPa] \\
$r_f$ & Coeff. & Probe recovery coefficient \\ 
$R_a/c_{pa}$ & Coeff. & Gas constant of air divided by specific heat of air 
at constant pressure
}
{ %%%%%% Outputs %%%%%%
$T_s$ & Vector & Static temperature [K]
}
{ %%%%%% Formula %%%%%%
\begin{displaymath}
 T_s = \frac{T_t}{1+r_f \left(\left(1+\frac{\Delta P}{P_s}\right)^{R_a/c_{pa}}
 -1\right)} \nonumber
\end{displaymath}
