Description

The surface radiative temperature has been incorrectly changed in the model.

It is important to understand that the implicit surface energy balance only provides an emitted long-wave radiation. From this we compute a corresponding surface radiative temperature by inverting the Stefan-Boltzmann relation.

The implicit solution of the energy balance computes an emitted long-wave flux which is a limited Taylor expansion of the future surface temperature around the current values. Thus the long-wave flux does not correspond to the new surface temperature but some intermediate value. So we need to deduce the radiative surface temperature to which this flux corresponds.

comment:1 Changed 8 years ago by jpolcher

  • Resolution set to fixed
  • Status changed from new to closed

Corrected with revision 2183 :

The surface radiative temperature is now again corectly computed. The comment

was updated so that a nybody wanting to change this again can educate
himself before.
