Investigation into the mechanisms of size-resolved particle dry deposition across three environments
… to changes in interception, caused by changes in plant physiology and surface structure during the winter that leads to an increase in their ability to uptake particles. Finally, we show particle and black carbon deposition from a low Arctic tundra during snow-cover that are elevated compared to …
