Abstract. Evaporation (E) and transpiration (T) respond differently to ongoing changes in climate, atmospheric composition, land use. It is difficult partition ecosystem-scale evapotranspiration (ET) measurements into E T, which makes it validate satellite data surface models. Here, we review current progress partitioning T provide a prospectus for how improve theory observations going forward. Recent advancements analytical techniques create new opportunities at the ecosystem scale, but...
Abstract Depending on season, rainfall characteristics and tree species, interception amounts to 15–50% of total precipitation in a forest under temperate climates. Many studies have investigated the importance different species all kinds Often authors merely determine storage capacity that specific considered event, only sometimes distinction is made between foliated non‐foliated trees. However, highly variable time space. First, since potential evaporation higher summer, but secondly...
The Budyko curve is often used to estimate the actual evaporation as a function of aridity index in catchment. Different empirical equations exist describe this relationship; however, these have very limited physical background. model concept presented paper physically based and uses only measurable parameters. It makes use two types evaporation: interception transpiration. assumes that can be modeled threshold process on daily time scale. If multiplied with rainfall distribution function,...
Abstract. Knowledge of the water fluxes within soil-vegetation-atmosphere system is crucial to improve use efficiency in irrigated land. Many studies have tried quantify these fluxes, but they encountered difficulties quantifying relative contribution evaporation and transpiration. In this study, we compared three different methods estimate during simulated summer conditions a grass-covered lysimeter laboratory. Only two can be used partition total into transpiration, soil interception. A...
Individual Fe atoms on a Cu2N/Cu(100) surface exhibit strong magnetic anisotropy due to the crystal field. Using atom manipulation in low-temperature STM we demonstrate that of one is significantly influenced by local strain second placed nearby. Depending relative positions two Cu2N lattice can controllably enhance or reduce uniaxial anisotropy. We present model explains observed behavior qualitatively terms first principles.
Abstract. In hydrological models, evaporation from interception is often disregarded, combined with transpiration, or taken as a fixed percentage of rainfall. general not considered to be significant process in rainfall-runoff modelling. However, it appears that on average can amount 20–50% the precipitation. Therefore, knowledge about important. Traditional research mainly focuses canopy and almost completely denies forest floor interception, although this an important mechanism precedes...
Abstract. Deforestation can considerably affect transpiration dynamics and magnitudes at the catchment scale thereby alter partitioning between drainage evaporative water fluxes released from terrestrial hydrological systems. However, it has so far remained problematic to directly link reductions in changes physical properties of system quantify these scale. As a consequence, is difficult effect deforestation on parameters catchment-scale models. This turn leads substantial uncertainties...
Abstract A system of two exchange-coupled Kondo impurities in a magnetic field gives rise to rich phase space hosting multitude correlated phenomena. Magnetic atoms on surfaces probed through scanning tunnelling microscopy provide an excellent platform investigate coupled impurities, but typical high temperatures prevent field-dependent studies from being performed, rendering large parts the inaccessible. We present study pairs Co insulating Cu 2 N/Cu(100), which each have temperature only...
Abstract. Near-surface wind speed is typically only measured by point observations. The actively heated fiber-optic (AHFO) technique, however, has the potential to provide high-resolution distributed observations of speeds, allowing for better spatial characterization fine-scale processes. Before AHFO can be widely used, its performance needs tested in a range settings. In this work, experimental results on novel observational wind-probing technique are presented. We utilized controlled...
Abstract. Thornthwaite's formula is globally an optimum candidate for large-scale applications of potential evapotranspiration and aridity assessment at different climates landscapes since it has lower data requirements compared to other methods especially from the ASCE-standardized reference (formerly FAO-56), which most data-demanding method commonly used as benchmark method. The aim study develop a global database local coefficients correcting monthly Thornthwaite (Ep) using (Er)....
Abstract. Scintillometers are used to measure path-integrated evaporation and sensible heat fluxes. They consist of a transmitter receiver separated along line sight several hundreds meters few kilometers. Turbulent eddies the associated refractive index fluctuations path between cause diffraction transmitted beam, known as scintillation effect. Optical microwave scintillometers have been designed full spectral range signal intensity caused by this phenomenon quantitatively link these...
Quantification of long-term partitioning precipitation into evaporation and runoff is a fundamental pursuit in catchment hydrology. The Budyko framework provides theoretical basis for this estimates the evaporative fraction based on aridity index via curve. However, deviations from global-average curve suggest additional controls beyond index. We hypothesized that root zone storage capacity (Sr), defined as maximum subsurface water accessible to vegetation roots, key driver these deviations....
Spatial evaporation estimates are essential information for studying the water cycle, yet amount of direct observations, such as Eddy-Covariance (EC) networks, limited. Satellites can also provide spatial estimates, but these based on indirect measurements surface conditions and contain many assumptions. As a new method, we explore potential commercial microwave links (CMLs), used in cellular telecommunication to be scintillometers. Scintillometers dedicated instruments measure...
Urban areas, with their dense populations and numerous socio-economic activities, are increasingly vulnerable to floods, droughts, heat stress due land use changes climate change. Traditionally, the urban thermal environment water resources management have been studied separately using surface models (ULSMs) hydrological (UHMs). However, as our understanding deepens urgency address future disasters grows, it becomes evident that hydroclimatological disasters—such severe...
Historically, the Netherlands has predominantly managed water surpluses, consequently numerical hydrological models are calibrated and validated under conditions ranging from average to wet. However, as prolonged drought periods become more frequent, there is a growing need for simulate dry conditions. One of key processes in simulation evaporation (E). This study seeks provide deeper understanding quantification actual (Eact) circumstances Dutch agricultural sector management practices. For...
Flash droughts are increasingly impacting the Dry Corridor of Central America, particularly in regions dominated by rainfed agriculture, further exacerbating pressures already faced ecosystems, and water resources management. These phenomena distinct from generally accepted concept due to their rapid intensification, often lasting for three weeks or more. Understanding how flash occur evolve, along with impacts, is closely linked geographical socioeconomic contexts affected areas. This...
Measuring evaporation through Bowen ratios requires measuring a wet and dry air temperature, something that is challenging to reliably accomplish in outdoor field conditions. In the context of forest evaporation, desire estimate as function height (e.g., partition above below canopy) adds another dimension complexity this measurement challenge.As part Ruijsdael Observatory Loobos, Netherlands, we aim continuously measure throughout profile, using wetted fiber-optic table along 40 m tower...
In general, quantitative precipitation estimates from weather radars are used as input into nowcasting models to produce high-resolution accurate and timely forecasts, up several hours ahead. However, the global distribution of (gauge-adjusted, ground- based) radar products is heavily skewed, largely favoring Europe, Northern America, parts East Asia. many low- middle-income countries, predominantly located in tropics, unavailable due high installation maintenance costs, rain gauges often...
Abstract. Quantification of precipitation partitioning into evaporation and runoff is crucial for predicting future water availability. Within the widely used Budyko framework, which relates long-term aridity index to evaporative index, curvilinear relationships between these indices (i.e. parametric curves) allow quantification under prevailing climatic conditions. A common assumption that movement along a specific curve with changes in over time can be as predictor catchment responses...
