Abstract. We report on the first multi-year kilometre-scale global coupled simulations using ECMWF's Integrated Forecasting System (IFS) to both NEMO and FESOM ocean–sea ice models, as part of H2020 Next Generation Earth Modelling Systems (nextGEMS) project. focus mainly an unprecedented IFS-FESOM setup, with atmospheric resolution 4.4 km a spatially varying ocean that reaches locally below 5 grid spacing. A shorter simulation 2.8 has also been performed. number shortcomings in original...
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...

Abstract. A ground-based field campaign was conducted in southern West Africa from mid-June to the end of July 2016 within framework Dynamics–Aerosol–Chemistry–Cloud Interactions (DACCIWA) project. It aimed provide a high-quality comprehensive data set for process studies, particular interactions between low-level clouds (LLCs) and boundary-layer conditions. In this region missing observations are still major issue. During campaign, extensive remote sensing situ measurements were at three...
Abstract. The Next Generation of Earth Modeling Systems (nextGEMS) project aimed to produce multi-decadal climate simulations, for the first time, with resolved kilometer-scale (km-scale) processes in ocean, land, and atmosphere. In only three years, nextGEMS achieved this milestone two km-scale system models, ICOsahedral Non-hydrostatic model (ICON) Integrated Forecasting System coupled Finite-volumE Sea ice-Ocean Model (IFS-FESOM). was based on cornerstones: 1) developing models small...

The Climate Adaptation Digital Twin within the Destination Earth project represents an innovative initiative aimed at achieving operational kilometer-scale global climate simulations to support adaptation efforts. Three state-of-the-art System Models (ESMs) are used separately and we focusing on scientific advancements simulation results of IFS-NEMO model throughout project's duration.During first phase project, two main were produced: a historical experiment (1990–2019) 10 km...
Abstract. During the West African summer monsoon season, extended nocturnal stratiform low-level clouds (LLCs) frequently form in atmospheric boundary layer over southern Africa and persist long into following day affecting regional climate. A unique data set was gathered within framework of Dynamics–Aerosol–Chemistry–Cloud Interactions (DACCIWA) project, which allows, for first time, an observational analysis processes parameters crucial LLC formation. In this study, situ remote sensing...
Abstract One‐dimensional radiative transfer solvers are computationally much more efficient than full three‐dimensional but do not account for the horizontal propagation of radiation and thus produce unrealistic surface irradiance fields in models that resolve clouds. Here, we study impact using a 3‐D solver on direct diffuse solar beneath clouds subsequent effect fluxes. We couple relatively fast approximation (TenStream solver) to Dutch Atmosphere Large‐Eddy Simulation (DALES) model...

Abstract The explicit coupling at meter and second scales of vegetation's responses to the atmospheric‐boundary layer dynamics drives a dynamic heterogeneity that influences canopy‐top fluxes cloud formation. Focusing on representative day during Amazonian dry season, we investigate diurnal cycle energy, moisture carbon dioxide canopy top, transition from clear cloudy conditions. To this end, compare results large‐eddy simulation technique, high‐resolution global weather model, complete...
Abstract. During the boreal summer, monsoon season that takes place in West Africa is accompanied by low stratus clouds over land stretch from Guinean coast several hundred kilometers inland. Numerical climate and weather models need finer description knowledge of cloud macrophysical characteristics dynamical thermodynamical structures occupying lowest troposphere, order to be properly evaluated this region.

Abstract. The misrepresentation of the diurnal cycle boundary layer clouds by large-scale models strongly impacts modeled regional energy balance in southern West Africa. In particular, recognizing processes involved maintenance and transition nighttime stratocumulus to shallow cumulus over land remains a challenge. This is due fact that vegetation, surface fluxes exhibit much larger magnitude variability than on more researched marine transitions. An improved understanding interactions...
