Publikováno v: Atmospheric Chemistry and Physics, Vol 21, Pp 12479-12493 (2021)

Black carbon (BC) is a significant forcing agent in the Arctic, but substantial uncertainty remains to quantify its climate effects due to the complexity of the different mechanisms involved, in particular related to processes in the snowpack after d

Publikováno v: Atmospheric Measurement Techniques, Vol 14, Pp 819-851 (2021)

The CAPS PMssa monitor is a recently commercialized instrument designed to measure aerosol single-scattering albedo (SSA) with high accuracy (Onasch et al., 2015). The underlying extinction and scattering coefficient measurements made by the instrume

Comparison of co-located refractory black carbon (rBC) and elemental carbon (EC) mass concentration measurements during field campaigns at several European sites

Publikováno v: Atmospheric Measurement Techniques, Vol 14, Pp 1379-1403 (2021)

The mass concentration of black carbon (BC) particles in the atmosphere has traditionally been quantified with two methods: as elemental carbon (EC) concentrations measured by thermal–optical analysis and as equivalent black carbon (eBC) concentrat

Cloud droplet activation properties and scavenged fraction of black carbon in liquid-phase clouds at the high-alpine research station Jungfraujoch (3580 m a.s.l.)

Autor: G. Motos, J. Schmale, J. C. Corbin, Rob. L. Modini, N. Karlen, M. Bertò, U. Baltensperger, M. Gysel-Beer

Publikováno v: Atmospheric Chemistry and Physics, Vol 19, Pp 3833-3855 (2019)

Liquid clouds form by condensation of water vapour on aerosol particles in the atmosphere. Even black carbon (BC) particles, which are known to be slightly hygroscopic, have been shown to readily form cloud droplets once they have acquired water-solu

Bromine, iodine and sodium in surface snow along the 2013 Talos Dome–GV7 traverse (northern Victoria Land, East Antarctica)

Autor: N. Maffezzoli, A. Spolaor, C. Barbante, M. Bertò, M. Frezzotti, P. Vallelonga

Publikováno v: The Cryosphere, Vol 11, Iss 2, Pp 693-705 (2017)

Halogen chemistry in the polar regions occurs through the release of halogen elements from different sources. Bromine is primarily emitted from sea salt aerosols and other saline condensed phases associated with sea ice surfaces, while iodine is affe

Environmental impact of Holstein Friesian and 3-breed crossbred dairy cows using a life cycle assessment approach applied to individual animals

Autor: L. Gallo, M. Berton, M. Piazza, E. Sturaro, S. Schiavon, G. Bittante

Publikováno v: Journal of Dairy Science, Vol 107, Iss 7, Pp 4670-4684 (2024)

ABSTRACT: This study aimed to set up a life cycle assessment (LCA) approach at the level of individual animals to assess the effects of a 3-breed crossbreeding program on the environmental impact of cows. The study involved 564 cows, 279 purebred Hol
