Hi there,
I am using ISAM to quantify the contributions of emissions in upwind regions to downwind O3. I am wondering whether the output for each tag represents O3 from direct transport, or from the combined effect of all model processes (transport, chemistry, deposition, etc.)? If all processes are integrated, is there a way to separate the direct O3 transport from those formed during the transport pathway or locally from transported precursors?
Thanks, and look forward to replies!
Best,
Bessie
