Simple models describing general ABL dynamics or output from NWP models representing varying synoptic conditions have been used to guide layer attribution. Measurement variables provide information on the probed atmosphere but are strongly dependent on sensor characteristics or measurement setup. 2015.a, Liu, S. and Liang, X. Meas. Turner, D. D. and Lhnert, U.: Ground-based temperature and humidity profiling: combining active and passive remote sensors, Atmos. To detect heights (or regions) of potential layer boundaries from attenuated backscatter profiles, a range of indicators has proven useful (see reviews by, for example, Emeis etal.,2008; Dang etal.,2019). This will help you to collect the data in a format you can use. Tech., 9, 58335852, https://doi.org/10.5194/amt-9-5833-2016, 2016.a, Bonin, T. A., Choukulkar, A., Brewer, W. A., Sandberg, S.

It is specifically designed to record downwelling radiance at high spectral resolution (0.5cm1). Naturally, utilising multiple sensors across an entire measurement network adds spatial information in the horizontal domain, which allows variations in layer heights to be assessed and interpreted (for example, in relation to surface forcing, local or regional circulations, synoptic conditions) but also for transport processes to be better detected (e.g. While layer detection methods (first derivative, WCT, and two-dimensional derivative) often agree, the greatest uncertainty in final products was associated with the step of layer attribution, even when considering simple categories only. 63620R.

It is specifically designed to record downwelling radiance at high spectral resolution (0.5cm1). Naturally, utilising multiple sensors across an entire measurement network adds spatial information in the horizontal domain, which allows variations in layer heights to be assessed and interpreted (for example, in relation to surface forcing, local or regional circulations, synoptic conditions) but also for transport processes to be better detected (e.g. While layer detection methods (first derivative, WCT, and two-dimensional derivative) often agree, the greatest uncertainty in final products was associated with the step of layer attribution, even when considering simple categories only. 63620R.
