Hello，all CMAQ user.
I had used CMAQv5.3.2 to simulate a personal cases from 2017.2.2-2017.2.7,including three domains.
In second domain , icon，bcon is produced by COMBINE_ACONC_v532_intel_2017js01_201702.nc in POST/combine/scripts/run_combine.csh file.
If you could some suggestions and solutions ,I would appreciate it.
Sincere
Xin-jiayi

The error message you are getting indicates you are looking for data one second before the first time step on the file. This data is not available, so the program aborts. The question is why the program is looking for data with this time stamp, or possibly why it is giving an incorrect error message.
In the default configuration provided in the CCTM run script, the ACONC file contains layer 1 only. If you then use the COMBINE program on the ACONC files and use that to generate your ICON and BCON files, you will not have sufficient data to run the nested domain.
The ICON log file you uploaded appears to be binary. I am unable to read it.
I still don’t know why the program is looking for a time one second before midnight. That is the ultimate cause of your error.
I have a few general suggestions:
Since you seem to be starting a new project, upgrade to the latest version of CMAQ. You are using v5.3.2, which is now two years old.
I recommend starting with the benchmark case, to be sure that CMAQ is working correctly on your system. Check your outputs against those provided by CMAS.
Check the outputs and logs of the coarse domain simulation. Did that run to completion and obtain reasonable results?
If you want to run a nested case, the simulation on the parent domain should output the most important species for all vertical layers. You then use those to generate initial and especially boundary conditions. Your ICON log file indicates you have used the ACONC file from layer 1 only to generate ICs and BCs. Your domain is quite small geographically, at only 13x13 columns and rows, which perhaps mitigates the error in neglecting species aloft, but in general this is not the recommended way to run the model.
Thank you for your question @Xin_jiayi and thank you for your suggestion @cgnolte .
I have encountered the similar problem (i.e., “Time step not available for file: INIT_CONC_1” and the requested time step is the strange “**:59:59”) using CMAQv5.3.3. I also tried v5.4 using the same set of input datasets. The problem remains.
The key to my question is just point four:
Previously i wrongly used the “COMBINE_ACONC*” file to generate ICON and BCON files for my nested domain. However, this “COMBINE_ACONC*” file contains only one layer. I guess this is why I cannot run CCTM correctly using ICON and BCON output from such conditions.
When making icon files for nested domains, you only need to use the first day of the aconc file of the first domain , but when making a bcon file, you need to use a loop to read the daily aconc file, the related solution is linked below.
