Tritium Atmospheric Transport and Deposition Following Acute Releases - Comparisons with a Simple Transport Model

Tritium deposition in pine trees and soil from atmospheric releases of molecular tritium.

Atmospheric Long-Range Transport and Deposition of Mercury to Alaska

Atmospheric transport and deposition of Indonesian volcanic emissions

A regional climate model has been used to study the transport and deposition of sulfur (SO2 and SO 2− 4 ) and PbCl2 emissions from Indonesian volcanoes. The sensitivity of the atmospheric loss of these trace species to meteorological conditions and their solubility was examined. Two experiments were conducted: 1) volcanic sulfur released as primarily SO2 and subject to transport, deposition, an...

Atmospheric transport and wet deposition of ammonium in North Carolina

Wet deposition and transport analysis has been performed for ammonium (NH` 4 ) in North Carolina, USA. Multiple regression analysis is employed to model the temporal trend and seasonality in monthly volume-weighted mean NH` 4 concentrations in precipitation from 1983 to 1996 at six National Atmospheric Deposition Program/National Trends Network (NADP/NTN) sites. A signi"cant (p(0.01) increasing...

Snow transport and deposition

The dynamics of snow erosion, transport and deposition due to the action of wind is still a controversial topic. Experts do not all agree on the mechanisms involved in this process and the eld remains rather empirical compared to other domain of science. We propose a new description of the phenomenon, based on a simple and intuitive model in which wind and snow \particles" are the basic compone...
