<<  CAM3 Installation problem on Itanium, http://bb.cgd.ucar.edu//viewtopic.php?t=124 >>

Message: Hello,
<br />
<br />I am trying to install CAM3 on an Itanium cluster, running on Linux. I am having problems with compiling the sources. It fails on BalanceCheckMod.F90 with the following error message:
<br />
<br />   module BALANCECHECKMOD
<br />     module subroutine BALANCECHECK
<br />
<br />    use time_manager, only : get_step_size, get_nstep
<br />
<br />Error 208 at (63:/home/cas/casnan/rpb/source/cam1/models/lnd/clm2/src/biogeophys/BalanceCheckMod.F90) : No such entity in the module

<br />I could only guess the 'missing' entities to be get_step_size and get_nstep. However, when I scroll up the console, I can see that time_manager.F90 has !
 been compiled properly with all the functions and subroutines listed as follows:
<br />
<br />   module TIME_MANAGER
<br />     module subroutine TIMEMGR_PRESET
<br />     module subroutine TIMEMGR_INIT

<br />I am using efc &amp; ecc compilers for the Itanium. Kindly help me as to what probably is going wrong.

<<  question about double CO2 exp., http://bb.cgd.ucar.edu//viewtopic.php?t=123 >>

Message: Dear All,
<br />
<br /> I am using CAM3 climatological SSTs as model forcing to do a double CO2 perturbed run,
<br /> and I  want to output the history file in the frequency of timestep. Specifically,
<br /> I'd like to take a look at the  results in  first 2 timesteps because the feedbacks are
<br /> not involved at that time.
<br />
<br />  For this purpose, I have read the user guide, but I am still not clear how to make
<br />  the change correctly.
<br />
<br />  1) In Page 66 of Table B.1: CAMEXP namelist variables(see user guide),
<br />   I find that the default value for variable "CO2VMR" is 3.550e-4. But I have
<br />  checked each files in  /cam1/models/atm/cam/bld, and can not find the name of
<br />  "CO2VMR". So How to make a double CO2 (2X 3.550e-4) in the model?
<br />   Also, I want to know why NCAR gives the value of 3.550e-4 for CO2 in the model
<br />    run using climatological SSTs as forcing? Where  is it from?
<br />
<br />   If another CO2 f!
 ile in the path "inputdata/atm/cam2/ggas/noaamisc.r8.nc" is used
<br />   for the run with monthly observed SSTs?
<br />
<br />  2) How to set the output frequency of timestep correctly?
<br />
<br />   Your suggestions are highly appreciated.
<br />
<br />   tao
