+For radiation calculations during spinup, a starting time is calculated based on the setting of [../radpar#time_utc_init time_utc_init] and [#spinup_time spinup_time], so that the spinup starts at {{{time_utc_init - spinup_time}}}. The timestamps during spinup will hence show negative values in the output data so that the coupled model system starts at {{{time_utc_init}}}, which equals the timestamp 0 in the output data.

-Parameter for steering of the spinup time. Depending on the model components switched on, these can run in a spinup phase without an interactive atmosphere. Currently, this mechanism is implemented for the land surface and the urban surface model. In the spinup phase, these models predict the skin and soil/wall temperatures. For using the spinup mechanism it is required to have a radiation model activated. Forcing is achieved by radiation and optionally a varying near-surface air temperature (steered via [#spinup_pt_mean spinup_pt_mean], [#spinup_pt_amplitude spinup_pt_amplitude], and the incoming solar radiation. After completion of the spinup, the atmospheric code is switched on and runs coupled to the surface models. Note that the near-surface temperatures are reset before coupling to their initial values prescribed by the user. The spinup mechanism can be steered via the additional parameters [#dt_spinup dt_spinup] and [#data_output_during_spinup data_output_during_spinup].
