Hello all,
I am running the WRF-Chem with hourly wrfchemi* emission files made by myself.
The emission files names are set as :
wrfchemi_d01_2013-11-27_12:00:00
wrfchemi_d01_2013-11-27_13:00:00
wrfchemi_d01_2013-11-27_14:00:00
etc…
Emissions like BC,OC,CO,CO2,NH3,NO,NO2,PM25,PM10,SO2 were put into the wrfchemi* file and the emissions units are in mol/(km^2•h)for gas phase species while in ug/(m^2•s)for aerosol species as required in user’s guide.
But the PM2.5 concentration values of the wrfout files are around 0.2~0.4ug/m^3 and the value seems impossible in realism.
Meanwhile, my PM10 has the same value of concentration with PM2.5 and I can’t solve the problem.
Anyone can solve the problems above?I’d really appreciate your help!
