Abstract. Due to the major role of sun in heating earth's surface, atmospheric planetary boundary layer over land is inherently marked by a diurnal cycle. The afternoon transition, period day that connects daytime dry convective night-time stable layer, still has number unanswered scientific questions. This phase cycle challenging from both modelling and observational perspectives: it transitory, most forcings are small or null turbulence regime changes fully convective, close homogeneous...
Abstract. Vertical profiles of temperature, humidity and wind up to a height 1500 m a.g.l. (above ground level) were measured with the automatically operating small unmanned research aircraft M2AV (Meteorological Mini Aerial Vehicle) during LITFASS-2009 LIndenberg-To-Falkenberg: Aircraft, Scintillometer large-eddy Simulation) experiment. The campaign took place in July 2009 over heterogeneous landscape around Meteorological Observatory Lindenberg – Richard-Aßmann-Observatory eastern part...
Abstract. Observations of turbulence are analysed for the afternoon and evening transition (AET) during Boundary-Layer Late Afternoon Sunset Turbulence (BLLAST) experimental field campaign that took place in Lannemezan (foothills Pyrenees) summer 2011. The case 2 July is further studied because properties lower atmosphere (up to 300 m above ground level) were sampled with Meteorological Mini Aerial Vehicle (M2AV) from turbulently mixed stably stratified atmospheric conditions. Additionally,...

We elaborate on the preliminary results presented in Beyrich et al. (in Boundary-Layer Meteorol 144:83–112, 2012), who compared structure parameter of temperature ( $${C_{T}^2}_{}$$ ) obtained with unmanned meteorological mini aerial vehicle $$\text{ M }^{2}\text{ AV } $$ versus two large-aperture scintillometers (LASs) for a limited dataset from one single experiment (LITFASS-2009). They found that data is significantly larger than LAS data. investigate if similar differences can be flights...
Abstract In the soil–plant–atmosphere continuum, fluxes of water, energy, and carbon determine water balance peat bogs. We used eddy covariance (EC) measurements to study surface atmosphere exchange its drivers above an ombrotrophic bog (Odersprungmoor) in Harz Mountains, Germany, with nonideal measurement conditions during growing season 2013. For montane peatlands, only very few EC flux exist due site constraints, for example, slope, limited fetch, frequent dew formation on open path...

Focusing on the basic structure as subject of justice has tended to lead theorists make a choice: either there is no global and therefore obligations remain domestic only (the statist position) or sufficient institutional basis at level warrant affirming in scope, meaning that duties must also be cosmopolitan position). Recent literature, however, pointed out this might false choice between denying asserting existence structure. There are two main claims I paper. First, claim Rawlsian...
Abstract. The article analyses airborne observations of turbulence in vertical and horizontal direction during the afternoon transition from turbulently mixed to stably stratified atmospheric conditions. data were obtained four flights at 14:30, 16:30, 18:30 20:30 UTC with Meteorological Mini Aerial Vehicle M2AV BLLAST field experiment summer 2011, which corresponds 18:30, 22:30 local time. Sunset was 19:42 UTC. anisotropy ratio defined here as variance wind speed changes a mean value about...
