Hi all,
I would like to kindly ask how to obtain the particle number for ultrafine particle (PM0.1) based on the framework of CMAQv5.4. As seen in AELMO file, we have PM_NUM (N m-3 ): Total Particle Number and N100 (N m-3 ): Total Particle Number greater than 100 nm.
Does it mean that I can simply use the value of PM_NUM minus N100 for getting the Ultrafine particle number ?
Any comments are highly appreciated!
