"Wet deposition" refers to the process by which pollutants in the atmosphere, such as acid rain, are brought down to the Earth's surface by rain, snow, or fog. Full definition
For the current climate, we calculate the reduction in wet deposition by dust radiative forcing and find that the aerosol burden is increased only modestly. (pubs.giss.nasa.gov)
The low deposition rate for the local sources (reduced wet deposition I guess) is a fair point however. (gfdl.noaa.gov)
When the model precipitation is brought to closer agreement with the observations, the AGCM accurately estimates dust loading over the Caribbean region, suggesting that rainfall errors cause the overestimation of wet deposition over the Atlantic. (pubs.giss.nasa.gov)
