I am simulating dust storms with WRF-Chem. Now the problem I am facing with is the values of PM10 are very high like from 10^16 until 10^32 and I dont know what is wrong. Additionally with just one domain run, the values are normal but by adding the other domains (I have 4 domain totally) the values turn out to be so high. I attach my namelist for you.

I am having a similar problem on some days during a year simulation (with 3 nested domains). The meteo variables seem to be good. Do you remember how did you solve this problem?

many thanks!
