Hi,    I am using theCESM1.2.2,F_2000_CAM5,where CAM5+CLM4+CICE+DOCN is used,the resolution is f09_g16. Starting simulation on Jan.1, the simulation stops in 15 days after the simulation. The error is exampled as follows: (shr_strdata_advance) ERROR: dt limit1    1126.00000000000   29.5000000000000        1.50000000000000 (shr_strdata_advance) ERROR: dt limit2        10116       43200       10215           0(shr_sys_abort) ERROR: (shr_strdata_advance) ERROR dt limit(shr_sys_abort) WARNING: calling shr_mpi_abort() and stopping (shr_strdata_advance) ERROR: dt limit1    1126.00000000000   29.5000000000000        1.50000000000000 (shr_strdata_advance) ERROR: dt limit2        10116       43200       10215           0 (shr_strdata_advance) ERROR: dt limit1    1126.00000000000    29.5000000000000        1.50000000000000

From the error it seems that you are trying to run for a period for which you don't have data. Cecile

Hi, I have the same problem with CESM1.2.2, compset F20C5TR, resolution f09_f09. I wonder if you have resolved this issue?
In my case I am trying to use custom SSTICE file which I created from previous experiments.
The Error is:
(shr_sys_abort) ERROR: (shr_strdata_advance) ERROR dt limit

(shr_strdata_advance) ERROR: dt limit1 62.0000000000000

(shr_strdata_advance) ERROR: dt limit2 19550201 0 19550301

These are my settings in the env_run.xml:
<!--"Prescribed SST and ice coverage stream name. (char) " --
<entry id="SSTICE_STREAM" value="CAMDATA" />
<!--"Prescribed SST and ice coverage data file name. (char) " -->
<entry id="SSTICE_DATA_FILENAME" value="$DIN_LOC_ROOT/atm/cam/sst/TSICE.e.e122.E_1850_CAM5.f09_g16.t4Ind_stg_co2b_cam5.cam.h0.1-49.nc" />
<!--"Prescribed SST and ice coverage grid file name. (char) " -->
<entry id="SSTICE_GRID_FILENAME" value="$DIN_LOC_ROOT/atm/cam/ocnfrac/domain.camocn.0.9x1.25_gx1v6_090403.nc" />
<!--"The model year that corresponds to SSTICE_YEAR_START on the data file. (integer) " -->
<entry id="SSTICE_YEAR_ALIGN" value="1955" />
<!--"The first year of data to use from SSTICE_DATA_FILENAME. (integer) " -->
<entry id="SSTICE_YEAR_START" value="1" />
<!--"The last year of data to use from SSTICE_DATA_FILENAME. (integer) " -->
<entry id="SSTICE_YEAR_END" value="49" />

and here is my docn_ocn_in:
&shr_strdata_nml
datamode = 'SSTDATA'
domainfile = '/oasis/scratch/comet/divanova/temp_project/cesm1_2_2/inputdata//share/domains/domain.ocn.0.9x1.25_gx1v6_090403.nc'
fillalgo = 'nn'
fillmask = 'nomask'
mapalgo = 'bilinear'
mapmask = 'dstmask'
streams = "docn.streams.txt.prescribed 1955 1 49"
taxmode = 'cycle'
tintalgo = 'linear'

This usually indicates some missing data. Does your SST/ICE file have monthly means? Are all of the years there from year 1 to 49? The error is indicating that there is a bigger gap in the data than what the model wants to interpolate between. So, for example if the model is expecting monthly mean data and there is a month missing, then this would be a gap of 2 months, which is larger than the dt_limit of 1.5.

Yes, indeed! I figured it out meanwhile. I created my SST file from CAM TS output and concatenated the monthly files in one with nco. In the final file I had time axis which was centered in the end of the month rather than in the middle (I guess something to do with the CAM set up?). After I shifted the time axis to have monthly values in the middle of the month the "dt limit" error was resolved. Thanks!

Hi, I am encountering something similar. Perhaps there is some insight into my issue?

My stream data is daily SST and ICE.

I have remapped the time to start from 1, and the date to start from year zero, same problem:

memory_write: model date = 10102 0 memory = 68.32 MB (highwater) -0.00 MB (usage) (pe= 768 comps= OCN)
(shr_strdata_advance) ERROR: dt limit1 2.00000000000000 1.00000000000000 1.50000000000000
(shr_strdata_advance) ERROR: dt limit2 10102 0 10103 0
(shr_strdata_advance) ERROR: dt limit1 2.00000000000000 1.00000000000000 1.50000000000000

Additionally, I constructed a 12 month file based upon the 33 time series, with appropriate 1/2 month time and half month dates. This executed correctly. However, I am trying to maximize the variability imposed upon the atmosphere, which is why I am attempting to use daily SST and ICE.
