arlmet.VerticalAxis#

class arlmet.VerticalAxis(levels, *, offset=0.0)[source]#

Abstract base class for ARL vertical coordinate axes.

Use from_flag() to construct from a raw ARL flag integer, or instantiate a subclass directly (e.g. PressureAxis(levels=[...])).

Parameters:

levels (sequence of float) – Native level values stored in the file.
offset (float, default 0.0) – Pressure offset used by sigma and hybrid coordinate conversions.

Methods

`VerticalAxis.__init__`(levels, *[, offset])
`VerticalAxis.calculate_coords`()	Return the native level coordinate values stored in the file.
`VerticalAxis.from_flag`(flag, levels, *[, offset])	Construct the appropriate subclass from an ARL vertical flag.
`VerticalAxis.to_height_agl`(**kwargs)	Compute height above ground level [m] at each level.
`VerticalAxis.to_pressure`(**kwargs)	Compute pressure [hPa] at each level.
