Abstract. Since 2010 an uninterrupted sequence of dry years, with annual rainfall deficits ranging from 25 to 45 %, has prevailed in central Chile (western South America, 30–38° S). Although intense 1- or 2-year droughts are recurrent this Mediterranean-like region, the ongoing event stands out because its longevity and large extent. The extraordinary character so-called megadrought (MD) was established against century long historical records a millennial tree-ring reconstruction regional...
Abstract. We introduce the first catchment dataset for large sample studies in Chile. This includes 516 catchments; it covers particularly wide latitude (17.8 to 55.0∘ S) and elevation (0 6993 m a.s.l.) ranges, relies on multiple data sources (including ground data, remote-sensed products reanalyses) characterise hydroclimatic conditions landscape of a region where situ measurements are scarce. For each catchment, provides boundaries, daily streamflow records basin-averaged time series...
Over the past 40 years, south-central Chile has experienced important land-use-induced land cover changes, with massive conversion from native forests (NF) to Pinus radiata D.Don and Eucalyptus spp. exotic forest plantations (FP). Several case studies have related this a reduction in water supply within small catchments (<100 ha). In work, we explore impacts of NF FP on streamflow by using large-sample catchment dataset recently developed for Chile. We select 25 large forested (>20,000...

Abstract Many remote sensing‐based evapotranspiration (RSBET) algorithms have been proposed in the past decades and evaluated using flux tower data, mainly over North America Europe. Model evaluation across South has done locally or only a single algorithm at time. Here, we provide first of multiple RSBET models, daily scale, wide variety biomes, climate zones, land uses America. We used meteorological data from 25 towers to force four models: Priestley–Taylor Jet Propulsion Laboratory...
Abstract. There is a wide variety of drought indices, yet consensus on suitable indices and temporal scales for monitoring streamflow remains elusive across diverse hydrological settings. Considering the growing interest in spatially distributed ungauged areas, this study addresses following questions: (i) What precipitation-based are most to assess catchments with different regimes? (ii) Do soil moisture outperform meteorological as proxies drought? (iii) Are snow more effective than...
Abstract. Droughts are often long lasting phenomena, without a distinct start or end, and with impacts cascading across sectors systems, creating long-term legacies. Nevertheless, our current perception management of droughts their is event-based, which can limit the effective assessment drought risks reduction impacts. Here, we advocate for changing this perspective viewing as hydro-eco-social continuum. We take systems theory focus on how “memory” causes feedback interactions between parts...

Plant breeding based on grain yield (GY) is an expensive and time-consuming method, so new indirect estimation techniques to evaluate the performance of crops represent alternative method improve yield. The present study evaluated ability canopy reflectance spectroscopy at range from 350 2500 nm predict GY in a large panel (368 genotypes) wheat (Triticum aestivum L.) through multivariate ridge regression models. Plants were treated under three water regimes Mediterranean conditions central...
Worldwide, urbanization constitutes a major and growing driver of global change distinctive feature the Anthropocene. Thus, urban development paths present opportunities for technological societal transformations towards energy efficiency decarbonization, with benefits both greenhouse gas (GHG) air pollution mitigation. This requires better understanding intertwined dynamics land use, emissions, demographics, governance, biophysical processes. In this study, we address several...
Vegetation biomass is a globally important climate-relevant terrestrial carbon pool and also drives local hydrological systems via evapotranspiration. of individual vegetation types has been successfully estimated from active passive remote sensing data. However, for many tasks, landscape-level maps across several are more suitable than types. For example, the validation ecohydrological models budgeting typically requires spatially continuous estimates, independent type. Studies that derive...
Soil moisture (SM) is a key factor influencing the interactions between atmosphere and processes at Earth&#8217;s surface.
