Are (dry/wet) deposition output files CCTM\_DRYDEP\* and CCTM\_WETDEP\* from a reference CMAQ output saved somewhere in the CMAS Data Warehouse? I am trying to compare the deposition of species for different seasons of the year between my CMAQ run and a reference CMAQ output in the Data Warehouse.

We do not have deposition data on the CMAS Data Warehouse at this time, other than the output from the small benchmark dataset which will not help in your case.
There is annual total deposition for 2002-2012 from CMAQv5.0.2 available here:
> **[CMAQ Output | US EPA](https://www.epa.gov/cmaq/cmaq-output#Deposition-shapefiles)**
>
> Visualize and probe CMAQ predictions using web based maps. Download CMAQ data files to use in your own research efforts.
The only place for seasonal CMAQ data, that I know of, is on EPA’s RSIG site: [RSIG Data Inventory | US EPA](https://www.epa.gov/hesc/rsig-data-inventory#cmaq)
This has hourly deposition data for 2002-2012 but it is also CMAQv5.0.2 output. We will be uploading a more recent set of hourly deposition data to RSIG this fall that uses CMAQv5.3.2.
