Characterization of the physical, chemical, and optical properties of atmospheric aerosol particles in New Hampshire
… Forest in northern NH showed that synoptic-scale air mass transport heavily influenced aerosol properties, and hence regional visibility. During W/SW flow, aerosol parameters and haziness were generally twice as high as times of N/NE flow. Similar transport dependent results were observed in …

Tracing the global carbon cycle with bomb radiocarbon
… shown to be a powerful tool for investigating air mass transport in atmospheric transport models. Second, a serious mismatch in the global bomb radiocarbon budget has been detected, suggesting that the oceans take up 25 less anthropogenic CO2 than hitherto believed. Third, tracking both the …

Aerosol processes in polar regions : from formation to climatic implications
Atmospheric aerosols affect our health, air quality, visibility and climate. They can impact the climate trough their ability to interact with radiation and to alter cloud properties by acting as cloud condensation nuclei (CCN) or ice nuclei (IN). Globally, aerosols cool the climate, but locally …

Studies of Arctic Tropospheric Ozone Depletion Events Through Buoy-Borne Observations and Laboratory Studies
… from coastal sites indicates that Arctic air masses devoid of O3 most often pass over sea ice-covered regions before arriving at an observation site, suggesting ODE chemistry occurs upwind over the frozen Arctic Ocean. However, outside of coastal observations, there exist very few …

Charakterisierung der troposphärischen Aerosolvariabilität in der europäischen Arktis
… Dicke, Angström Koeffizient, usw.) und dem Transport des Aerosols sowohl auf kurzen Zeitskalen (Tagen) als auch auf langen Zeitskalen (Monate, Jahre). Um diesen Zusammenhang herzustellen, werden für die kurzen Zeitskalen mit dem Trajektorienmodell PEP-Tracer 5-Tage Rückwärtstrajektorien in …

Comparative aerosol studies based on multi-wavelength Raman LIDAR at Ny-Ålesund, Spitsbergen
… as well as large scale pressure patterns and air mass origin regions. Here, it was not possible to find a clear correlation between enhanced AOD and air mass origin. However, in a comparison of two cloud free periods in March 2007 and April 2009, large AOD values in 2009 coincided with air …
