Abstract The critical bulk Richardson number (RiBc; defined over the entire stable boundary layer) is commonly utilized in observational and modelling studies for the estimation of the boundary layer height. Traditionally, RiBc is assumed to be a quasi-universal constant. Recently, based on large-eddy simulation and wind-tunnel data, a stability-dependent relationship has been proposed for RiBc. In this study, we analyze extensive observational data from several field campaigns and provide further support for this newly proposed relationship
