    3 One of the main challenges in LES modeling is the turbulence closure. The filtering process yields four SGS covariance terms (see the first five equations Sect. [wiki:doc/tec/gov governing equations]) that cannot be explicitly calculated. In PALM, two different subgrid-scale models are available to parameterize the SGS terms:
