[cam-users] Problem with CWAT

[Barbara Grassi]

 Dear users,

  I'm running CAM2 model on IBM AIX machine

  I didn't modify the CAM source code but when I run the model
  I get a lot of these messages

 QNEG3 from convtran1/CWAT:m=  1 lat/lchnk=385 Min. mixing ratio
violated at    1 points.  Reset to  0.0E+00 Worst =-2.8E+00 at i,k=   5
14

 from the beginning of the run (NSTEP=0).

 I'm using the following file to set initial and boundary conditions:

 cami_0000-09-01_64x128_T42_L26_c020514.nc
 sst_HadOIBl_bc_64x128_1949_2001_c020411.nc
 noaao3.1990.21999.nc
 abs_ems_factors_fastvx.052001.nc

 Could you give me some indications about the possible origin of this
 problem?

 Thanks, Barbara
