A novel framework for analyzing rainy season dynamics in semi-arid environments: a case study in the Peruvian Rio Santa basin Open
In semi-arid regions, the timing and duration of the rainy season determines plant water availability, which directly impacts food security. Rainy season metrics, which aim to define and, in some cases, predict the onset and end of seasona…

Towards a more reliable GPP estimation: A systematic assessment of using the photochemical reflectance index as a proxy for non-photochemical quenching Open
Resolving the global terrestrial CO2 budget remains a pressing challenge with implications for achieving internationally agreed emissions targets. To this end, remote sensing of solar-induced chlorophyll fluorescence (SIF) is rapidly advan…

Non-radiative effects dominate the local surface temperature response to land-cover change—Insights from a semi-empirical model Open
Land-cover change (LCC) is an important driver of climate change through carbon emissions (biochemical effects), but also through changes in the surface energy balance (biophysical effects). Quantifying magnitude and sign of surface temper…

From over to under, a story about the vertical within-canopy variation of the leaf relative uptake rate of COS Open
The gross primary productivity (GPP), which represents the gross uptake of carbon dioxide (CO2) by plants, cannot be directly measured at the ecosystem level. It must instead be inferred either by applying models or by measuring proxies. A…

Establishing the Photochemical Reflectance Index (PRI) as a reliable proxy for Non-Photochemical Quenching (NPQ) Open
On a global scale, the scientific community is to date unable to close the CO2 budget, with implications for policymakers in regard to limiting global warming to internationally agreed levels. Recently, remote sensing of Solar-Induced Chlo…

Exploring the feasibility of early stress detection with sun-induced chlorophyll fluorescence from tower to satellite  Open
Terrestrial ecosystems are undergoing increasingly frequent periods of stress as the climate is changing. Monitoring ecosystem health efficiently requires global spatial coverage and high temporal resolution, which are assets of satellite-…

Untangling the importance of dynamic and thermodynamic drivers for wet and dry spells across the Tropical Andes Open
Andean vegetation and agriculture depend on the patterns of rainfall during the South American monsoon. However, our understanding on the importance of dynamic (upper-level wind circulation) as compared to thermodynamic (Amazon basin moist…

Widespread greening suggests increased dry-season plant water availability in the Rio Santa valley, Peruvian Andes Open
In the semi-arid Peruvian Andes, the growing season is mostly determined by the timing of the onset and retreat of the wet season, to which annual crop yields are highly sensitive. Recently, local farmers in the Rio Santa basin (RSB) repor…

Elevation-dependent surface temperature changes in the Andes Open
<p>On average, surface temperatures are rising globally, but the pace of warming varies with regional factors. Rates of warming are expected to increase with elevation, a phenomenon referred to as elevation-dependent warming (EDW). D…
