There is some confusion about data selection

[tom_cruise]

I want to do pm2.5 validation and now I found two datasets for each:
(1): MERRA-2 tavgU_2d_aer_Nx: 2d,diurnal,Time-averaged,Single-Level,Assimilation,Aerosol Diagnostics V5.12.4 (M2TUNXAER)
(2) MERRA-2 tavgM_2d_aer_Nx: 2d,Monthly mean,Time-averaged,Single-Level,Assimilation,Aerosol Diagnostics V5.12.4 (M2TMNXAER)
If I want to do validation of pm2.5 concentration for monthly mean, can I use a second dataset validation code?
