 'absolute_value': The absolute instantaneous values of all prognostic variables but vertical velocity are recycled, so that the values at the inflow boundary and the recycling plane are identical (for vertical velocity, still only the turbulent fluctuations are recycled). With this method there is no horizontal temperature (humidity) gradient and thus the circulation and the instabilities at the inflow boundary will not occur. Note that the mean inflow profiles of  all prognostic variables but vertical velocity will now change in time (growing boundary layer).\\\\
 
-'absolute_value_thermodynamic_quantities': The absolute instantaneous values of potential temperature and (if present) humidity are recycled. For all other prognostic variables the turbulent fluctuations are recycled. With this method there is no horizontal temperature (humidity) gradient and thus the circulation and the instabilities at the inflow boundary will not occur. Note that the mean inflow profiles of potential temperature (humidity) will now change in time (growing boundary layer), in contrast to the inflow profile of all other quantities (e.g. u,v,w) that are constant. In order to avoid this mismatch, the boundary layer height should be kept constant by applying a [#large_scale_subsidence large_scale_subsidence] to scalar quantities.
