COLDSST: encountered in cldfrc

[rangel@lamce_coppe_ufrj_br]

Dear users, I'm running CAM5 standalone, and I'm facing a problem that I do not know how to solve. First, I'm interpolating CFS data to CAM's grid, overwriting some variables of the initial file (cami-mam3_0000-01-01_1.9x2.5_L30_c090306.nc) and also the sst file (sst_HadOIBl_bc_1.9x2.5_clim_c061031.nc). Then, I configure and point the CAM build-namelist to those files:  ../../configure -v -fc gfortran -dyn fv -hgrid 1.9x2.5 -nospmd -nosmp -debug -test ../../build-namelist -test -v -config /home/clima/CESM/cesm1_2_1/models/atm/cam/bld/10rodada_membros/m1/config_cache.xml -namelist "&atm ncdata='/home/clima/CESM/cesm1_2_1/models/atm/cam/bld/10rodada_membros/m1/cami_1.9x2.5_L30_c20180505.nc' start_ymd=101 stop_option='nmonths' stop_n=3  bndtvs='/home/clima/CESM/cesm1_2_1/models/atm/cam/bld/10rodada_membros/m1/sst_HadOIBl_bc_1.9x2.5_clim_c20180505.nc' /"./cam >& cam.out The output "log" file shows this message several times:COLDSST: encountered in cldfrc:         121           5  0.12830816980450577        258.95364400148389 COLDSST: encountered in cldfrc:         122           5  0.21456958848813840        258.66823598146436 The final lines of cam.out: *** halting in modal_aero_lw after nerr_dopaer =        1000(shr_sys_abort) WARNING: calling shr_mpi_abort() and stoppingMPI_Abort: error code = 1001MCT::m_Router::initp_: RGSMap indices not increasing...Will correctMCT::m_Router::initp_: GSMap indices not increasing...Will correctMCT::m_Router::initp_: GSMap indices not increasing...Will correctMCT::m_Router::initp_: RGSMap indices not increasing...Will correctMCT::m_Router::initp_: RGSMap indices not increasing...Will correctMCT::m_Router::initp_: GSMap indices not increasing...Will correctMCT::m_Router::initp_: GSMap indices not increasing...Will correctMCT::m_Router::initp_: RGSMap indices not increasing...Will correctMCT::m_Router::initp_: RGSMap indices not increasing...Will correctMCT::m_Router::initp_: GSMap indices not increasing...Will correct  And then the model stops. What could be happening?I looked for the "COLDSST" message here in the forum and found one post, but without answers. (https://bb.cgd.ucar.edu/node/1001366)  Any help will be appreciated.

The error is coming from this code in models/atm/cam/src/physics/cam/cloud_fraction.F90     ierror = 0
    do i=1,ncol
       ! Adjust thetas(i) in the presence of non-zero ocean heights.
       ! This reduces the temperature for positive heights according to a standard lapse rate.
       if(ocnfrac(i).gt.0.01_r8) thetas(i)  = &
            ( sst(i) - lapse * phis(i) / gravit) * (pnot/ps(i))**cappa
       if(ocnfrac(i).gt.0.01_r8.and.sst(i).lt.260._r8) ierror = i
       clc(i) = 0.0_r8
    end do
    coef1 = gravit*864.0_r8    ! conversion to millibars/day

    if (ierror > 0) then
       write(iulog,*) 'COLDSST: encountered in cldfrc:', lchnk,ierror,ocnfrac(ierror),sst(ierror)
    endif


My guess is that it's related to changes to the SST dataset.

Hi Eaton.Perhaps I made a mistake when interpolating the sst field. I'll check this now.Thanks!
