Please do not create duplicate posts. You already asked this question in a [new thread you created](https://forum.cmascenter.org/t/cmaq-simmulation-concentation-of-pm25-too-low/5654). Adding the same question to an existing older thread only leads to clutter and will not provide you with a faster response.
