Beyond the boundary: a new road to improve photosynthesis via wind Open
Plants interact with their microclimate, simultaneously responding to and influencing it. A key element in this interaction is the leaf boundary layer: a stagnant air layer enveloping the leaf, creating a resistance to heat and gas exchang…

Next-generation hybrid precipitation forecasts that integrate Indigenous knowledge Open
Many smallholder farmers in the Global South utilize local forecasts based on Indigenous knowledge due to limited reliability and accessibility of scientific weather forecasts. The use of local forecast, however, faces challenges by increa…

Increasing complexity in Aerodynamic Gradient flux calculations inside the roughness sublayer applied on a two-year dataset Open
Over tall canopies such as forests the atmospheric surface layer is subdivided into an inertial sublayer (ISL) and a roughness sublayer (RSL). Inside the RSL the classic aerodynamic gradient method using Monin-Obukhov similarity theory (MO…

Numerical Investigation of Observational Flux Partitioning Methods for Water Vapor and Carbon Dioxide Open
While yearly budgets of CO 2 flux ( F c ) and evapotranspiration ( ET ) above vegetation can be readily obtained from eddy‐covariance measurements, the separate quantification of their soil (respiration and evaporation) and canopy (photosy…

Understanding in and above canopy-atmosphere interactions by combining large-eddy simulations with a comprehensive observational set Open
<p>The vegetated canopy plays a key role in regulating the surface fluxes and, therefore, the global energy, water and carbon cycles. In particular, vulnerable ecosystems like the Amazonia basin can be very sensitive to changes in ve…

Plants, vital players in the terrestrial water cycle Open
<p>Plant transpiration accounts for about half of all terrestrial evaporation (Jasechko et al., 2013). Plants need water for many vital functions including nutrient uptake, growth, maintenance of cell turgor pressure and leaf cooling…

Direct numerical simulation of laminarization in the atmospheric boundary layer Open
A well-known phenomenon in the atmospheric boundary layer is the facts that winds may become very weak in the evening after a clear sunny day. In these quiet conditions usually hardly any turbulence is present. Consequently, this type of b…
