| The mixing height is a key parameter for many applications that relate
surface–atmosphere exchange fluxes to atmospheric mixing ratios, e.g., in
atmospheric transport modeling of pollutants. The mixing height can be
estimated with various methods: profile measurements from radiosondes as well
as remote sensing (e.g., optical backscatter measurements). For quantitative
applications, it is important to estimate not only the mixing height itself
but also the uncertainty associated with this estimate. However, classical
error propagation typically fails on mixing height estimates that use
thresholds in vertical profiles of some measured or measurement-derived
quantity. Therefore, we propose a method to estimate the uncertainty of an
estimation of the mixing height. The uncertainty we calculate is related not
to the physics of the boundary layer (e.g., entrainment zone thickness) but
to the quality of the analyzed signals. The method relies on the concept of
statistical confidence and on the knowledge of the measurement errors. It can
also be applied to problems outside atmospheric mixing height retrievals
where properties have to be assigned to a specific position, e.g., the
location of a local extreme. |
