In this version, the computation of some diagnostic fields has been changed in the turbulence. Also, some technical adaptations have been done.
The interpolation to the diagnostic levels has been changed. In particular, no more exponential canopy profile is assumed, but a diagnostic Prandtl layer interpolation is used even for scalars, using an adopted canopy layer resistance (and standard SYNOP lawn).
| Note: | Because the 2m temperature is used in the soil model, these changes do influence not only the results of the field T_2M, but also the whole forecast. |

On February 18th, the COSMO_EU got a hard limit violation of the surface
pressure for the RTTOV library: the model pressure was 1100.14 hPa!!
But this was at the Death Sea, which is not too unrealistic, because there were
rather cold temperatures by that time.
Now, the surface pressure given to the RTTOV-library is limited by 1100 hPa
(which is the hard limit).

Some new fields have been introduced to the COSMO-Model (for later use)
and some fields now got official GRIB numbers.

The changes in the computation of the 2m temperature also influence the
whole forecast, because it is used as input to the soil model.
