Hi everyone. I am using the data from EQUATE to do my simulation in a smaller domain The time is from 04/22/2016 to 05/22/2016. I created my own mcip files, ICON and BCON files. Now I have a small problem that I cannot start my CMAQ from April 22 00:00:00. It cannot extract INIT\_CONC\_1. So I modified to 01:00:00. But for next day I still need to start from 00:00:00. The attachment is my script for my simulation. I just want to know how to solve this problem so I won’t miss one hour.

How are you creating your initial conditions? In particular, are there reasons preventing you from creating initial conditions for 00:00:00 on April 22 if that is the desired start date and time for your CMAQ simulation? ---

I create the initial condition from file CCTM\_CONC\_v532\_intel18.0\_CMAQv53\_TS\_108NHEMI\_201604\_dailyav.nc This is the script file: [run\_icon\_201604.txt](https://forum.cmascenter.org/uploads/short-url/yCUyjU5aklAyobgVWVI7wqEwgyF.txt) (5.2 KB) ---

What is the first time stamp of your April 22, 2016 MCIP files - 00:00:00 or 01:00:00? In particular, what are the time stamps for file /scratch/mnpfubl/mcip/2016\_04d1/METCRO3D\_20160422d1.nc which you are specifying as MET\_CRO\_3D\_FIN in your icon run script? It would be helpful if you could post your icon log file in addition to your icon run script. Thanks! ---

I used ncdump get the information of METCRO3D\_20160422d1.nc and also attached the icon log file in the attachments.

Thanks for posting these files. Your icon log file shows that the time stamp in the output file /scratch/mnpfubl/Build\_CMAQ/CMAQ\_project/data/icon/ICON\_v54\_2016\_04midd1\_regrid\_20160422 is 2016113:000000 (0:00:00 April 22, 2016), which is what you intend. Going back to your first post, it is not clear why it seems CCTM cannot read INIT\_CONC\_1 for 0:00:00 April 22, 2016 (“Now I have a small problem that I cannot start my CMAQ from April 22 00:00:00. It cannot extract INIT\_CONC\_1. So I modified to 01:00:00.”). To help us track down the reason for this error, you would need to post the CCTM log file for the simulation in which you tried to start from April 22 00:00:00 and encountered an error. ---

Hi, Christian. I will post them tomorrow. Cause the model is still running now. Thanks for your quick reply 😃 ---

Hi, Christian. I used the sample script on my 2016.08 to 2016.09 simulation. It works. For simulation in April, I start in a early time to get the result I want. I will continue update when I enough disk space to reproduce the April error to help find bugs.
