Equivalent black carbon concentration measured with an aethalometer AE33 during the Arctic Ocean 2018 expedition
Julia Schmale, Andrea Baccarini, Benjamin Jérémy Laurent Heutte
Equivalent black carbon (eBC) mass concentration was measured with a commercial aethalometer (model AE33, Magee Scientific, Berkeley, USA). Measurements were performed onboard of the Swedish icebreaker (I/B) Oden from August to September 2018 as part of th ...
EPFL Infoscience2024Light absorption by brown carbon over the South-East Atlantic Ocean
Biomass burning emissions often contain brown carbon (BrC), which represents a large family of light-absorbing organics that are chemically complex, thus making it difficult to estimate their absorption of incoming solar radiation, resulting in large uncer ...
COPERNICUS GESELLSCHAFT MBH2022Forward scattering of snow as a factor in local surface energy balance and winter PV production
Because of its high albedo, snow changes the surface energy balance very signiKcantly and this introduces a strong positive feed-back loop with the local climate. In complex, mountainous terrain, the high albedo causes shortwave solar radiation to be reQec ...
2021High-Q surface electromagnetic wave resonance excitation in magnetophotonic crystals for supersensitive detection of weak light absorption in the near-infrared
The mid-infrared spectrum can be recorded from almost any material, making mid-infrared spectroscopy an extremely important and widely used sample characterization and analysis technique. However, sensitive photoconductive detectors operate primarily in th ...
OPTICAL SOC AMER2020Carbon fluxes and productivity regimes in Alpine streams
High-altitude catchments have a major role in the transport of organic matter to streams due to the storage of dissolved organic carbon (DOC) in soils and glacier ice and the subsequent mobilization during the melting processes. Yet, stream function goes b ...
EPFL2020Vibrational Sum Frequency Scattering in Absorptive Media: A Theoretical Case Study of Nano-objects in Water
Sylvie Roke, Saranya Pullanchery Sankara Narayanan, Sergey Kulik
The structures of interfaces of nano- and microscale objects in an aqueous solution are important for a wide variety of physical, chemical, and biological processes. Vibrational sum frequency (SF) scattering has emerged as a useful and unique probe of the ...
AMER CHEMICAL SOC2020Dissolved organic carbon in snow cover of the Chinese Altai Mountains, Central Asia: Concentrations, sources and light-absorption properties
Dissolved organic carbon (DOC) in snow plays an important role in river ecosystems that are fed by snowmelt water. However, limited knowledge is available on the DOC content in snow of the Chinese Altai Mountains in Central Asia. In this study, DOC in the ...
2019The role of glacier retreat for Swiss hydropower production
Pedro Filipe De Almeida Manso, Bettina Schaefli
High elevation or high latitude hydropower production (HP) strongly relies on water resources that are influenced by glacier melt and are thus highly sensitive to climate warming. Despite of the wide-spread glacier retreat since the development of HP infra ...
2018Modulation of snow reflectance and snowmelt from Central Asian glaciers by anthropogenic black carbon
Deposited mineral dust and black carbon are known to reduce the albedo of snow and enhance melt. Here we estimate the contribution of anthropogenic black carbon (BC) to snowmelt in glacier accumulation zones of Central Asia based on in-situ measurements an ...
2017Light-absorbing impurities enhance glacier albedo reduction in the southeastern Tibetan plateau
Light‐absorbing impurities (LAIs) in snow of the southeastern Tibetan Plateau (TP) and their climatic impacts are of interest not only because this region borders areas affected by the South Asian atmospheric brown clouds but also because the seasonal snow ...
