    Properties

    baseFt?: number

    Base altitude in feet MSL. Undefined when the base is the surface (SFC) or the freezing level (see baseIsFreezingLevel).

    baseIsFreezingLevel?: boolean

    True when the base altitude is the freezing level rather than a fixed altitude. When set, baseFt is undefined because the freezing level varies geographically.

    topFt: number

    Top altitude in feet MSL.
