<<  CAM3 failure to time interpolate aerosol data, http://bb.cgd.ucar.edu//viewtopic.php?t=27 >>

Message: When running the cam3 from 15 sep 1999, it fails at 16 Dec 12Z. It reports the errror:
<br />    Offset 0x0000018c in procedure __abortutils_MOD_endrun, near line 44 in file /scratch/scratchdirs/u14201/cam30/cam1/models/atm/cam/src/control/abortutils.F90
<br />    Offset 0x00000184 in procedure __prescribed_aerosols_MOD_aerint, near line 1290 in file /scratch/scratchdirs/u14201/cam30/cam1/models/atm/cam/src/physics/cam1/prescribed_aerosols.F90
<br />
<br />line1290 in the routine 'prescribed_aerosols.F90' is the logic whereby the model is trying to find the bounding months to perform the time interpolation. At 16 Dec 12z evidently it flips from the bounding months: Nov(month=11) - Dec( month=12) to: Dec( month=12) - Jan(month=1). The cycle logic fails. 
<br />
<br />I am running at T42, the cam3 T42 aerosol data set has the 'time' variable (12 values) all set to missing, but the model probably does not use these values or else it would have failed earlier.
<br />
<b!
r />The model has been run (at NCAR) through many Decembers, so I am at a loss as to what is going on? 
<br />
<br />A difference is that I am running the model in forecast mode, so I am starting the model at the cyclic crossover rather than running through this  point in a continuous fashion. Using CAM2 I could run with cyclic SSTs without a problem. I will go look at the code for the SSTs and see how it differs from the aerosol.
<br /> 
<br />Thanks for any help.
<br />Jim
