Discover LudwigThe phrase "upper altitude" is not commonly used in written English and may sound awkward.
It can be used when referring to higher elevations or levels in a specific context, such as aviation or geography, but it is better to use more standard terms. Example: "The aircraft reached an upper altitude of 30,000 feet before cruising."

Therefore, high 7Be concentrations with respect to low 210Pb concentrations could indicate strong air subsidence from upper altitudes, which can increase surface 7Be and O3 concentrations, because these components are produced mainly in the stratosphere/upper troposphere (Cristofanelli et al. 2006, 2015; Cuevas et al. 2013; Tsutsumi et al. 1998; Zanis et al. 1999).
