Deposition - height range selection

Post by Xiao » May 2nd, 2018, 1:26 pm

Hi,

I am a little confused about deposition. In the tutorial, to show the concentration display, the height range is from 0 to 100 m (as in the attached image).
Why is it the average concentration between a height range, instead of the concentration at 0 m level?
Also, is 100 m generally used, or does this height range vary with species of pollutants?
If I select "yes" in the control file for wet deposition, does the obtained concentration in 0-100 m include wet deposition? As I understand, pollutants removed from atmosphere by wet deposition will enter water body or into the soil, is it correct? If so, then in a rainy day simulation, is there a way to check the results for wet deposition, say, removal rate, total amount of pollutant be washed way, etc.?

Thank you very much!

Xiao

Please check the following information about deposition in the model:
https://www.ready.noaa.gov/documents/Tu ... m_dry.html
https://www.ready.noaa.gov/documents/Tu ... m_wet.html

the deposition layer is set at 0 m. So the model will not do any averaging between the deposition and concentrations.
