Influence of warm and moist air intrusions on black carbon deposition and snowmelt in the central Arctic
In the central Arctic, warm and moist air intrusions (WAMIs) are increasingly prevalent during winter and spring, significantly affecting the near-surface energy budget. Here, we combine in situ observations from the 2019–2020 Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition with model simulations to investigate the role of WAMIs in transporting pollutants and enhancing black carbon (BC) wet deposition. S…
Modelling the coupled mercury-halogen-ozone cycle in the central Arctic during spring
Near-surface mercury and ozone depletion events occur in the lowest part of the atmosphere during Arctic spring. Mercury depletion is the first step in a process that transforms long-lived elemental mercury to more reactive forms within the Arctic that are deposited to the cryosphere, ocean, and other surfaces, which can ultimately get integrated into the Arctic food web. Depletion of both mercury and ozone occur due to the presence of reactive h…
Low ozone dry deposition rates to sea ice during the MosaiC field campaign: Implications for the Arctic boundary layer ozone budget
Dry deposition to the surface is one of the main removal pathways of tropospheric ozone (O3). We quantified for the first time the impact of O3 deposition to the Arctic sea ice on the planetary boundary layer (PBL) O3 concentration and budget using year-round flux and concentration observations from the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) campaign and simulations with a single-column atmospheric chemist…
Overview of the MosaiC expedition: Atmosphere
With the Arctic rapidly changing, the needs to observe, understand, and model the changes are essential. To support these needs, an annual cycle of observations of atmospheric properties, processes, and interactions were made while drifting with the sea ice across the central Arctic during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition from October 2019 to September 2020. An international team desig…
Navajo Electrification for Sustainable Development: The Potential Economic and Social Benefits
Using data from the United States Census 1990, the Energy Information Administration estimated in 2000 that 36.8 percent of the 29,375 occupied housing units on the Navajo Nation lacked electricity. The Navajo Nation has very low population densities, and the large distances between homes make the cost of providing conventional sources of electricity prohibitive. Arizona Public Service, the primary provider of electricity in Arizona, estimates th…
Jargon der Eigentlichkeit
Capitalistic production and reproduction are total and totalitarian; they invade every nook and cranny, to the point that even free time and fresh air, culture and leisure, become commodities to be bought and sold, packaged and publicized. The history of the past two centuries, reflected in its art, literature and philosophy, can be characterized by the degree to which the logic of commodities has extended its hold; and, on this plane, one could …
