3.2.5. Interpolation of forcing data at the model time step

Generally, the forcing time step is longer than the model time step.

That is why a linear interpolation is realized for nearly all atmospheric parameters, except for RAIN and SNOW that are set equal to the value at the end of the current forcing time step (that is the mean rate of rain during the spell between the two forcing time steps).
