The level of the ground relative to the ASHES coordinate system origo (zero-level). We recommend thinking of the mean sea level (MSL) as the zero-level since the MSL is a common reference for ground elevation.

The value must be positive or 0.

This value is used to estimate the air density if the option From temperature and altitude is selected for the air's Density scheme. And in this case it is treated as above mean sea level (AMSL or MAMSL).

Note that the MSL cannot be set explicitly for onshore simulations (as opposed to offshore simulations).

  • Default value: 0
  • Unit: $\text{m}$
  • Range: 0 — 10000
