NH3 wet deposition - CMAQ5.4 - M3DRY

CMAQ
1

Hi,
Are there reports or papers documenting the NH3 wet deposition in CMAQ? I’ve only found studies on dry deposition.
I use CMAQ5.4 with the M3DRY scheme, and my NH3 WDEP in RDN is marginal. This RDN is composed by DDEP NH4, WDEP NH4 and DDEP NH3. Does it mean gaseous ammonia is quickly transformed into NH4 or dry deposited?
Best regards
Matthieu

CMAQ assumes that ammonia gas in transformed into NH4 when it dissolves in water

thank you! It’s very good to know. Is there a reference somewhere?
