According to the TIGGE+ list these variables are missing:
Precipitation: grid-scale only, hail (kg/m^2) acc_st 218 201 SURF
Precipitation rate: grid-scale only, hail (kg/s/m^2) inst 221 201 SURF
Precipitation: convective, snow (kg/m^2) acc_st 078 002 SURF
Precipitation: convective, graupel (kg/m^2) acc_st 217 201 SURF
Precipitation: convective, hail (kg/m^2) acc_st 219 201 SURF
Cloud top height (m) inst 087 201 SURF
Convective cloud top height (m) inst 069 201 SURF
Convective cloud bottom height (m) inst 068 201 SURF
Sunshine duration (s) acc_st 020 201 SURF
In most cases the missing variables are no longer part of the model physics of LMK, because there is no parametrization of convection.
