Description Usage Arguments Details Value References Examples

This is used to transform units: [mm] to [nm/s²]

1	facTopo_from_grid(gravity_component_grid3d, ...)

gravity_component_grid3d

data.frame, supplying the gravity grid. Needs columns x, y, z, Depth, gcomp (gravity component value).

missing

Returns the topographic conversion factor which represents the gravity effect resulting from 1 mm of vertical water storage change. This factor is used to convert mm of water from precipitation or evapotranspiration measurements, etc. to gravity units [nm/s²].
