Different quantities provide insights into ABL dynamics and can be analysed to derive the heights of the various sub-layers (Sect.

The presence of clouds increases uncertainty in CBLH retrievals for all methods (Sect. Continuous variables can theoretically take on an infinite number of values - the accuracy of the measurement is limited only by the measuring instrument.

Given their impact on layer height uncertainty, measurement setup (such as MWR calibration, DWL focal setting and scan strategy, aerosol lidar optical overlap, amongst others; Sect. 50, 100, and 250m at <500, 5002000, and >2000m, respectively), this spacing should not be confused with the actual vertical resolution, which by definition is the minimum distance at which differences in the vertical profile are resolved.

In situ data obtained on tall towers, on tethered balloons, or using UASs, for example, usually provide very detailed information; however, observations from the airborne platforms tend to lack temporal coverage. But valuable characteristics can also be determined from wind and turbulence data alone, for example to differentiate between buoyancy- or shear-driven turbulence (Tucker etal.,2009), surface or elevated turbulence sources (Tonttila etal.,2015; Manninen etal.,2018; Huang etal.,2020; Harvey etal.,2015), and elevated turbulence sources associated with either the flow (e.g. The various physical quantities (Sect. Generally, a differentiation can be made between ALCs that provide high-SNR observations and those with rather low SNR (Kotthaus etal.,2020).

Sugimoto, N.: Evolution of a lidar network for tropospheric aerosol Improved process understanding and quantitative knowledge of ABL dynamics are hence crucial for a wide range of applications with high societal, economic, and health impacts, including the assessment of air quality (e.g. Thus, a frequency distribution for gender would have two nonoverlapping classes to show the number of males and females.

Banta, R.M., Senff, C.J., White, A. Schmid and Niyogi (2012) improve the detection of CBLH by allocating heights where a change in the vertical v gradient coincides with a dew point temperature inversion.

The sign of the vertical velocity skewness provides information on the source of turbulence, with positive values typical of surface-driven buoyancy in clear-sky CBL and negative values associated with cloud-topped boundary layers dominated by downwards convection that is driven by radiative cooling at the cloud top (Hogan etal.,2009).

J. Meteorol., 181, 95123. By the end of this section you should: Understand what the variables are and why they are used. The vertical profile of air temperature in the SBL often shows a characteristic surface-based temperature inversion (SBI), whose height (SBIH) can be very meaningful in restricting vertical dilution.

In addition, consumables of high-power lidars are expensive, so that most operators limit measurements to times when no low-level liquid water clouds are present as these extinguish the lidar signal at very low altitudes. Thus, the data values of 28, male, single, and $30,000 would be recorded for a 28-year-old single male with an annual income of $30,000.

Choosing the appropriate technology for a given network not only needs to consider the physical information content of the atmospheric quantity observed (temperature, humidity, wind, turbulence, aerosol, or trace gases) but also whether the sensitivity, resolution, and capabilities of a given sensor are appropriate to monitor the layer(s) of interest. Different sub-layers occur within the ABL depending on atmospheric stability. Rfenacht, R., Haefele, A., Pospichal, B., Cimini, D., Bircher-Adrot, S., TKE can also be obtained by scanning at the specific elevation angle of 35.5 (Eberhard etal.,1989). 3.3). Boundary Layer Height on Short Spatial and Temporal Scales: A Demonstration Examining continuous variables can give you important information: Do all subjects have data, or are values missing? In general, IRS data have greater information content than MWR, resulting in higher vertical resolution for temperature and humidity profiles, and sensitivity to trace gases and cloud particle size. Recent advanced approaches (Bonin etal.,2018; Krishnamurthy etal.,2021) combine a diverse set of atmospheric variables, which enables reliable layer detection under nearly all atmospheric conditions.

To account for differences in ABL heights associated with cloud dynamics, ALC data have also been used to automatically distinguish between simple cloud types (Kotthaus and Grimmond,2018a).

Meteor. Some stations operate automatic launch systems that can introduce temperature and humidity uncertainties in the lowest altitudes (<200m) as sondes are located in climate-controlled chambers before being released into ambient air (Madonna etal.,2020). In general, uncertainties in layer height detection vary with time of day and differ between the layer targeted.
