All attributes are element-wise and only for horizontal and 3D models.

Attribute:

NMKL [-] (only for Meßer method),

NKID [-] (RUBINFLUX method),

In the Meßer method, the elements are categorised into 6 climatope classes depending on the potential evapotranspiration (attribute NETP). In the RUBINFLUX method, the IDs for the associated climate zones are assigned to the elements.

The division of the classes is discussed in detail in the chapter calculation of the groundwater recharge rates .
