Could anyone help me with the input dataset.

[dfeijat@126_com]

Dear CAM3.0 developers,
I am trying to run the cam3.0 with the monthly observed SSTs, sst_HadOIBl_bc_128x256_1949_2001_c020812.nc, but when I submit the job, the model stop with the followings errors:
+16382 0: Successfully initialized time variant variables
+16383 0:
+16384 0: Successfully initialized the land model
+16385 0: begin initial run at:
+16386 0: nstep= 0 year= 0 month= 9 day= 1 seconds= 0
+16387 0:
+16388 0:******************************************************
+16389 0:
+16390 0: SSTINI: Failed to find dates bracketing ncdate, ncsec= 831 85800
+16391 0: ENDRUN: called without a message string


My question is, is there something wrong with the dataset, sst_HadOIBl_bc_128x256_1949_2001_c020812.nc, or somewhere in my namelist?

To show the errors that encountered me clearly, I give the namelist with which I cam verbosely as following:

Shall you tell me how can I correct the errors?

Thanks in advance!

The problem is in the namelist. By default the initial time of the run is read from the initial file which in this case is 0000-09-01. This time is not contained in the SST dataset you specified. Set an appropriate initial date using the namelist variable start_ymd.

---------------------------------------------------------------------

I have try it immediately, it really works.

But I have another question as following:

why should I set the start_ymd et al., could the model initial time of the run be set to be 0000-01-01 ?

Or in other words, why the model set to start run from 0000-09-01 but not 0000-01-01 ? Could anyone tell me the reason ? Or could anyone give me some conceptual hints about ?


Thank you in advance !
