Overview of the Alaskan Layered Pollution and Chemical Analysis (ALPACA) Field Experiment

Athanasios Nenes, Julia Schmale, Andrea Baccarini, Roman Pohorsky, Sukriti Kapur

The Alaskan Layered Pollution And Chemical Analysis (ALPACA) field experiment was a collaborative study designed to improve understanding of pollution sources and chemical processes during winter (cold climate and low-photochemical activity), to investigat ...

On the dependence of Water Use Efficiency on aridity.

Gabriele Manoli, Sara Bonetti

Water use efficiency (WUE) describes how efficiently plants transpire water to assimilate carbon and produce biomass. Here, we used a variety of data sources, including leaf-level gas exchange measurements, tree-ring isotopes, flux-tower observations, and ...

Assessing the impact of urban heat islands on the risks and costs of temperature-related mortality

Gabriele Manoli

Ambient temperatures have an impact on human health, with unfavourably warm and cold conditions both associated with elevated mortality risk. By modulating the temperature in urban environments, urban heat islands (UHIs) can therefore both amplify the impa ...

A review of Water Use Efficiency across space and time

Gabriele Manoli, Sara Bonetti

Water Use Efficiency (WUE) is the variable linking assimilation and storage of carbon in plants with the release of water through transpiration. In this study, we combine multiple datasets including global scale leaf-level gas exchange measurements, tree-r ...

Report - Action Lab “Sufficiency in the Swiss Habitat” 06-2022

Sascha Nick

This first Action Lab focused on the basics, such as how people understand sufficiency, how they feel about it, how they discuss (or don’t) this topic, and who should be at the table for future rounds. It was named “Sufficiency in the Swiss Habitat”, and p ...

Tree root distribution modelling in different environmental conditions

David Andrew Barry, Paolo Perona, Massimiliano Schwarz

The ability to predict the spatial distribution of tree root system variables (e.g., the Root system Area (RA), the maximum root diameter, the number of roots in diameter classes, the density of fine roots, etc.) under different environmental conditions is ...

A mechanistic assessment of urban heat island intensities and drivers across climates

Gabriele Manoli, Ziyan Zhang

The urban heat island effect (UHI) has been widely observed globally, causing climate, health, and energy impacts in cities. The UHI intensities have been found to largely depend on background climate and the properties of the urban fabric. Yet, a complete ...

Deliberative democracy, climate, sufficiency, and possible application to public health

Sascha Nick

Could deliberative democracy, and specifically citizens' assemblies be applied to engaging the broad population on public health? The experience of the Academic Citizens’ Assembly on climate and sufficiency is promising. How could this be adapted for impro ...

Transmittance thresholds of electrochromic glazing to achieve annual low-glare work environments

Marilyne Andersen, Jan Wienold, Sneha Jain

A recent study on the glare protection performance of electrochromic (EC) glazing showed that visible transmittance levels lower than 0.6% are necessary to achieve comfortable situations for sun positions, that were close to the central field of view. Howe ...

Solar energy potential at the Great St Bernard Pass

Josef Andreas Schuler, Pietro Florio, David Notzon

The historical site of the Great St Bernard Pass, situated in the Alps at an elevation of 2469 m, records very high electricity consumptions. This study aims at evaluating the photovoltaic potential at the pass. The analysis was performed on the envelope s ...
