Special Issue Information

Dear Colleagues,

Land-atmosphere interaction is a key-aspect in several atmospheric processes of the surface layer and, more generally, of the Planetary Boundary-Layer. This interaction determines the energy balance at the surface, which, in turn, influences turbulence, atmospheric stability, and surface-layer structure. There is nowadays a strong interest in the scientific community in the measurement and modeling of atmosphere-surface exchange, over different typologies of surfaces, of energy, tracers, and pollutants for studying both air quality implications and impact on climate in urban, coastal, and remote sites. The vertical exchange (flux) of water vapor is an essential part of the water balance in the biosphere. The determination of vertical net exchange of CO2 over forest and vegetated surfaces is extremely important in determining the CO2 concentration levels and trends at a global scale and has an important role in climate change scenarios. The net balance between pollutant emission and deposition in urban areas and its parameterization is a key-step in modeling and in the evaluation of the role of urban agglomerates and mega-cities on air quality, health, and climate.

Manuscripts on all aspects of land-atmosphere interactions are welcome for this special issue.

Abstract: Wave-like motions are a fundamental characteristic of the SBL dynamics on a wide variety of scales. Even if the influence of gravity waves on the atmospheric dynamics is being increasingly recognized, a detailed knowledge of the properties of such wavelike disturbances and of their modalities of interaction with turbulence is yet missing. In this work, the characteristics of gravity waves and their impact on turbulent statistics and fluxes have been studied by analyzing data collected on an Antarctic Ice sheet during an Austral Summer. Antarctica is an ideal location for studying the characteristics of the gravity waves for the persistent conditions of strong atmospheric stability in the lower troposphere. Periods interested by wavelike motions have been identified by analyzing time series measured by fast response instrumentation. The nature and characteristic periods of wavy motions have been investigated by Fourier co-spectral indicators. Moreover a multi-resolution decomposition has been applied in order to filter gravity waves from turbulent fluctuations in case of a defined spectral gap. Statistics computed after removing wavy disturbances highlight the importance to filter gravity waves to avoid overestimations in turbulent parameters and errors in turbulent flux calculations.

Title: Air Pollutants Reduction by Urban Trees: Comparison between the i-Tree and the EMEP Models

Abstract: There is a growing interest to identify and quantify the benefits provided by the presence of trees in urban environment in order to improve the environmental quality in cities. However, the evaluation and estimate of plants efficiency in removing atmospheric pollutants is rather complicated, because of the high number of factors involved and the difficulty of estimating the effect of the interactions between the different components. In this study the i-Tree and the EMEP MSC-W models are tested and compared to identify the main strengths and weaknesses, with the intent to improve the estimates. These two models are internationally recognized as semi-empirical models designed for different applications, but with several common points that allow to share parts of the algorithm to estimate the deposition and to understand the main reasons of the reported divergences. The comparison shows a good agreement in the estimates and highlights how the methodology presented in this study may have significant opportunities for further developments.
