Special Issue Information

Dear Colleagues,

Most human activities take place within the atmospheric boundary layer (ABL), the layer of the atmosphere closest to the Earth's surface. The ABL is directly influenced by the exchange of heat, moisture, and aerosol and gaseous constituents with the surface, as well as the biosphere and the anthropogenic activities. Furthermore, the main physical phenomena occurring in the ABL, such as temperature, wind, humidity, fog, clouds and precipitation, have a direct influence on human activities. Atmospheric profiling allows the measurement and characterization of atmospheric conditions at various heights, and hence, is critical for improving weather forecasts, air quality, and the projections of future climate scenarios, thereby leading to a better understanding of the atmospheric processes occurring in the climatic system. Energy security, public health and safety, transportation, water resources, and food production are the five societal requirements that necessitate  the determination and characterization of the ABL height and profile, respectively. Ground-based sensors and satellite observations provide information on the high temporal variability and strong vertical gradients experienced within and above the ABL. Despite its significance, the ABL remains the most important under-sampled part of the atmosphere, and the scientific community is still trying to fill this informational gap.

With this aim and aligned with the objectives of the EU COST action PROBE (http://probe-cost.eu), this Special Issue is open to contributions dealing primarily with the remote sensing of the ABL, including support from in situ data, modelling approaches, and synergy using different techniques and equipment.

The wave turbulence interactions in the stable boundary layer (SBL) of the atmosphere are studied based on data from lidar measurements of the vertical component of wind velocity during the propagation of internal gravity waves (IGWs). It is shown that as an IGW appears, the amplitude of the spectra of turbulent fluctuations of vertical wind velocity nearby the frequency of quasi-harmonic oscillations induced by an IGW increases significantly, sometimes by several orders of magnitude, compared to the spectra in the absence of an IGW. Since IGW energy is transferred to small-scale turbulence, the amplitude of spectra with the Kolmogorov–Obukhov −5/3 power-law frequency dependence in the inertial frequency range increases. The slope of the spectra in the low-frequency range between the frequency of IGW-induced oscillations and the frequency of the lower boundary of the inertial range exceeds the slope, corresponding to the −5/3 power-law dependence. In this frequency range, the spectra obey the power-law dependence on the frequency with the exponent ranging from −4.2 to −1.9. The average value of the exponent −3 is consistent with a low-frequency slope caused by IGWs in turbulent spectra in the lower SBL. Full article
