about inputdata

[liufuhong123@163_com]

1. I want to run CAM at resolution of 10x15 and I have downloaded the inputdata from the NCAR web (cam3.1_19x24_10x15_datasets.tar.gz). But when I built the namelists by 'build-namelist' with a '-test' option,there was a warning like this:

fhliu@gcrc:~/case> ../cam/cam1/models/atm/cam/bld/build-namelist -test
Warning(camexp::checkinputfile): ncdata dataset /home/fhliu/cam/ not found on local disk
This dataset must be copied or linked to the run directory.
Warning(camexp::checkinputfile): bndtvaer dataset /home/fhliu/cam/atm/cam/rad/AerosolMass_V_10x15_clim_c031022.nc not found on local disk
This dataset must be copied or linked to the run directory.
Warning(clm2exp::checkinputfile): fsurdat dataset /home/fhliu/cam/lnd/clm2/srfdata/cam/clms_10x15_c040716.nc not found on local disk
This dataset must be copied or linked to the run directory.
Write out namelist to: namelist '

It seems that I need two inputdata files,AerosolMass_V_10x15_clim_c031022.nc and clms_10x15_c040716.nc.What I want to know is whether I can download the inputdata from web?


2. I want to run CAM model in a ideal condition and I don't need the landform,distribution of land-ocean,even gradient of temperature between different latitude.How to modify the source code for my purpose?

If you reply to my email address below then I can send you the missing files, I am not sure why they are absent for that resolution.

For running cam in idealized mode you can select aqua_planet mode in the namelist options
AQUA PLANET = .true.
which removes all the land and just has ocean which you can specify in analytical form in the SST input file

See http://www.ccsm.ucar.edu/models/atm-cam/docs/usersguide/usersguide.pdf
for more details.

i've replaced the 10x15 tarball with a complete set of needed files - thanks
for bringing this to our attention...will look for other incomplete sets
