A summary of the variables in this file is given in
Section 1.4.1.
The parameters in qtcmpar.in are generated by a Fortran 77 program, par.f.
One can compile par.f using a command f77 -o par par.f,
and then run par.
It produces the file, qtcmpar.in. The input reference profile for par.f is
Tqo3.ref which includes SST (K), air temperature (K), water vapor mixing
ratio (kg/kg), and ozone mixing ratio (kg/kg) in 1 hPa interval from 1000 hPa
to 1 hPa.
Note: The par.f program is not included in the current QTCM1 (v2.0) package;
interested users should contact the development team directly.
For calculating a1, 950 hPa cloud base and
200 hPa cloud top are used. Below the
cloud base, the atmosphere is dry adiabatic; above the cloud base, the
atmosphere is moist adiabatic.
A relative humidity of 0.8 is used to calculate b1.
Tqo3.ref is used to calculate reference values of the gross moist stability
and the gross moisture stratification.
However, the model is sensitive to
qtcmpar.in, so reasonable values are assigned to the gross moist stability
(3.5) and the gross moisture stratification (3.0), and cloud top is set
at 200 hPa at this moment.
