I updated SMAT-CE v1.6 with monitored ozone design values in 2018,2019, and 2020 in the U.S. When I run SMAT, I get the following error:  
Fail to read monitor data “NAME OF THE CSV FILE WITH OZONE MONITORED DATA”  
I checked the format of the updated file and it does match with the format of the original file. I am not sure what’s wrong since the error is not specific. Any ideas on how to address this issue would be much appreciated!

Here is a snippet of the updated csv file

I figured out the error was due to duplicates and some mismatch in sorting the data.
