AERMOD PM2.5 monthly averages

Hi all. I want to generate monthly average for PM2.5, i’ve read the AERMOD Userguide and it says cannot applied for POLLUTID PM2.5. Therefore, i ran the 24-hr and annual averages for PM2.5. Is it possible to get the monthly data from 24-hr .PLT output file? bc when i checked the 24-hr data .PLT file, the monthly row is not appear for 12 month, only several months appeared. Thank you
