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 ...

Performance of energy piles foundation in hot-dominated climate: A case study in Dubai

Lyesse Laloui, Elena Ravera, Sofie Elaine ten Bosch

Energy piles represent an innovative technology that can help provide sustainable geothermal heating or cooling energy for thermal conditioning purposes. In hot-dominated climates, the interest is to inject heat in the ground and extract energy for space-c ...

Near-bed stratification controls bottom hypoxia in ice-covered alpine lakes

Damien Bouffard, Camille Roland Marie Minaudo, Tomy Doda, Hugo Nicolás Ulloa Sánchez, Hannah Elisa Chmiel, Janine Rüegg, Nicolas Thomas Georges Escoffier, Pascal Perolo

In ice-covered lakes, near-bottom oxygen concentration decreases for most of the wintertime, sometimes down to the point that bottom waters become hypoxic. Studies insofar have reached divergent conclusions on whether climate change limits or reinforces th ...

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 ...

The role of Encapsulants in the long-term performance of advanced Crystalline Silicon Glass-Glass PV modules

Luca Gnocchi

The adoption of crystalline silicon (c-Si) PV modules based on glass-glass (G-G) structures is gaining momentum because of the possibility to manufacture bifacial panels, collecting light from the rear side. Despite not being an optimal material, Ethylene ...

Simulation of long-term spatiotemporal variations in regional-scale groundwater recharge: contributions of a water budget approach in cold and humid climates

Emmanuel Qays Dubois

Groundwater recharge (GWR) is a strategic hydrologic variable, and its estimate is necessary to implement sustainable groundwater management. This is especially true in a global warming context that highly impacts key winter conditions in cold and humid cl ...

Planning Multi-Scale District Energy Systems with Hybrid Cooling Technologies and Decentralized Thermal Networks for Low Carbon Cities in the Tropics

Shanshan Hsieh

Energy demand for cooling of buildings is projected to drastically increase in the next decades. Urban areas in tropical Asia are expected to contribute a major share to this growing demand. These areas are characterized by a high urban density and a diver ...

Ship-based measurements of ice nuclei concentrations over the Arctic, Atlantic, Pacific and Southern oceans

Julia Schmale, André Welti

Ambient concentrations of ice-forming particles measured during ship expeditions are collected and summarised with the aim of determining the spatial distribution and variability in ice nuclei in oceanic regions. The presented data from literature and prev ...

Optimized Design of Silicon Heterojunction Solar Cells for Field Operating Conditions

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin, Brahim Aissa, Olivier Denis Dupré

Solar modules are currently characterised at standard test conditions (STC), defined at 1000 W/m2 and 25 °C. However, solar modules in actual outdoor operating conditions typically operate at lower illumination and higher temperature than STC, which signif ...

Rainfall retrieval with commercial microwave links in Sao Paulo, Brazil

Timothy Hugh Raupach

In the last decade there has been a growing interest from the hydrometeorological community regarding rainfall estimation from commercial microwave link (CML) networks. Path-averaged rainfall intensities can be retrieved from the signal attenuation between ...
