I wonder if anyone know the wet deposition calculation difference between CMAQ-5.0 and CMAQ-5.3. I did a same simulation using same input files using CMAQ5.3.2 and compared that with 5.0.2 and found large difference in wet deposition of a PM species(100000*APHGJ).
The following results is at one site of a day. The left is 5.0.2 and the right is 5.3.2. 5.0.2’s wet deposition is much larger than 5.3.2.
By the way, i run the benchmark before and my wet deposition simulation is very close to the standard output. Part of my run script is also shown below.
Any related thoughts are appreciated!!!
