    symbol

    description

    unit

    variable name

    \(\theta_{S}\)

    sensor zenith angle

    \(deg\)

    sensor_zenith_angle {:}

    \(\theta_{V}\)

    viewing zenith angle

    \(deg\)

    viewing_zenith_angle {:}

    The pattern : for the dimensions can represent {time}, or no dimensions at all.

    \[\theta_{V} = 180 - \theta_{S}\]
