(shr_stream_verifyTCoord) ERROR: calendar dates must be increasing

[chaitri]

I am trying to run MUSICAv1 with a new grid created for India. I have created the case, set it up, and built it successfully. When I submit the case I face a runtime error of the following:

CN Soil matrix solution is off
CN Soil matrix solution is off
CN Soil matrix solution is off
ERROR: (shr_stream_verifyTCoord) ERROR: calendar dates must be increasing
(shr_stream_verifyTCoord) ERROR: calendar dates must be increasing
(shr_stream_verifyTCoord) date(n), date(n+1) = 20130616 18500101


After going through the log files, I noticed the model crashes while streaming at ocn. I am attaching the relevant files. Kindly help me to solve the issue?

What version of the code are you using?
version used: ctsm5.3, cesm3_0_beta05
res: mpasa60-3-India_g17_mg17
compset: FCHIST

Have you made any changes to files in the source tree?
Yes, created a grid for India and specified it in the env_run.xml and env_build.xml

Thanks!

@chaitri, when you say "crashes while streaming at ocn" do you mean that the last thing done by the model relates to reading an ocean-related stream?

The error that you show indicates a problem with the stream's dates. You will have to figure out whether the problem is inside the stream data (and if you're using custom data, then this seems likely), or whether the problem is due to corresponding namelist settings.

I have a troubleshooting suggestion that may help:
Take a step back and run a default case (no changes from you) to confirm that it works (maybe you have done this already). When that's successful, I suggest that you compare the failing case to the successful case by taking a difference between the case directories (i.e. where you submit the runs from):

diff case_failing case_successful > dif.out

Look at dif.out for differences between the cases that might explain the error.
Try reducing the differences between the two cases until you narrow down to the difference that causes the error.

Also, you may receive more specific guidance by posting in the ocean forum instead of in the land forum. I will go ahead and move this thread to the ocean forum since your error appears in the ocn.log file. Or, actually, since this is in an F-case, I will move to the general CESM forum. Another alternative may be the chemistry forum...
