Abstract. The Meso-NH Atmospheric Simulation System is a joint effort of the Centre National de Recherches Météorologiques and Laboratoire d'Aérologie. It comprises several elements; numerical model able to simulate atmospheric motions, ranging from large meso-alpha scale down micro-scale, with comprehensive physical package, flexible file manager, an ensemble facilities prepare initial states, either idealized or interpolated meteorological analyses forecasts, post-processing graphical...
Abstract. The current version of the Dutch Atmospheric Large-Eddy Simulation (DALES) is presented. DALES a large-eddy simulation code designed for studies physics atmospheric boundary layer, including convective and stable layers as well cloudy layers. In addition, can be used more specific cases, such flow over sloping or heterogeneous terrain, dispersion inert chemically active species. This paper contains an extensive description physical numerical formulation code, gives overview its...
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 The influence of dry‐air entrainment on surface heat fluxes and the convective boundary‐layer (CBL) properties is studied for vegetated land surfaces, using a mixed‐layer CBL model coupled to Penman–Monteith equation under wide range conditions. In order address complex behaviour system, feedback mechanisms involved were put into mathematical framework. Simple expressions evaporative fraction Priestley–Taylor parameter derived, based concept equilibrium evaporation. Dry‐air enhances...
Abstract Forests impact regional hydrology and climate directly by regulating water heat fluxes. Indirect effects through cloud formation precipitation can be important in facilitating continental-scale moisture recycling but are poorly understood at scales. In particular, the of temperate forest on clouds is largely unknown. Here we provide observational evidence for a strong increase cover over large regions western Europe based analysis 10 years 15 min resolution data from geostationary...

The diurnal and vertical variability of heat carbon dioxide (CO 2 ) in the atmospheric surface layer are studied by analyzing measurements from a 213 m tower Cabauw (Netherlands). Observations thermodynamic variables CO mixing ratio as well profiles turbulent fluxes used to retrieve contribution budget terms scalar conservation equation. On basis daytime evolution fluxes, we calculate assuming that follow linear profile with height. This assumption is carefully tested deviation linearity...
Abstract. Ambient total OH reactivity was measured at the Finnish boreal forest station SMEAR II in Hyytiälä (Latitude 61°51' N; Longitude 24°17' E) July and August 2010 using Comparative Reactivity Method (CRM). The CRM – method is a direct, in-situ determination of loss rate hydroxyl radicals (OH) caused by all reactive species air.

Abstract Atmospheric aerosol plays critical roles in suppressing planetary boundary layer (PBL) and deteriorating air quality. However, comprehensive understanding on how optical properties (absorption scattering) affect PBL remains lacking. Utilizing a large‐eddy simulation model incorporated with situ observations, we demonstrate distinct impacts of absorption development when it is present below (stove effect promotion) or above morning residual (dome strong inhibition) similar inhibition...
Abstract. This paper describes the background, instrumentation, goals, and regional influences on HUMPPA-COPEC intensive field measurement campaign, conducted at Boreal forest research station SMEAR II (Station for Measuring Ecosystem-Atmosphere Relation) in Hyytiälä, Finland from 12 July–12 August 2010. The prevailing meteorological conditions during campaign are examined contrasted with those of past six years. Back trajectory analyses show that site 2010 were characterized by a higher...
Global warming increases the number and severity of deadly heatwaves. Recent heatwaves often coincided with soil droughts that intensify air temperature but lower humidity. Since lowering humidity may reduce human heat stress, net impact desiccation on morbidity mortality remains unclear. Combining weather balloon satellite observations, atmospheric modelling, meta-analyses heatwave mortality, we find droughts—despite their effect—lead to a mild reduction in lethality. More specifically,...
Satellite measurements of tropospheric NO2 columns are valuable for monitoring long-term changes in air quality. However, direct linkage satellite-derived trends with underlying NOx emissions and surface concentrations is complicated by the contribution background to column, chemical regime wherein take place, data sampling differences. Here we study 2005–2018 nitrogen oxides over polluted Netherlands. We use QA4ECV OMI retrievals, RIVM NO, NO2, O3, wet deposition fluxes nitrate, reported...
Nitrogen oxides (NO x ) play a central role in catalyzing tropospheric ozone formation. dioxide 2 has recently reemerged as key target for air pollution control measures, and observational evidence points toward limited understanding of high-NO environments. A complete the mechanisms controlling rapid atmospheric cycling between (O 3 )–nitric oxide (NO)–NO regimes at surface is therefore paramount but remains challenging because competing dynamical chemical effects. Here, we present...
Abstract Vegetation and atmosphere processes are coupled through a myriad of interactions linking plant transpiration, carbon dioxide assimilation, turbulent transport moisture, heat atmospheric constituents, aerosol formation, moist convection, precipitation. Advances in our understanding hampered by discipline barriers challenges the role small spatiotemporal scales. In this perspective, we propose to study atmosphere–ecosystem interaction as continuum integrating leaf regional scales...
Irrigation in semi-arid regions induces thermal heterogeneity across a range of spatial scales that impacts the partitioning energy at surface, development atmospheric boundary layer, and bidirectional interactions between atmosphere surface. In this analysis, we use data from Land Surface Interactions with Atmosphere Iberian Semi-Arid Environment (LIAISE) experiment combined coupled land–atmosphere model to understand role irrigation-induced, on surface fluxes consequently, diurnal...
