how to read the cam2.r restart file? thanks!

The cam2.r.* restart file is a binary sequential file. There is no easy way to read it. The only way is to look at the CAM code that reads restart files and duplicate the procedure. We do plan to convert CAM's restart files to netCDF sometime in the near future.

Thank you very much!
but,i can't read the restart file. how can i design a experiment in which i need to change the "ts"?

Cam produces initial files which are not strictly restart files, but the are easier to read netcdf files. See the 'CAM Users' Guide' as to how to output cam initial files

As designing a land surface Ts change experiment please provide much more information as which fields you wish to change/investigate nad how.

dear rneale:

Thanks for your help!
i find a problem that it has severe difference between the result of monthly average model output data runing with restart file and runing with initial file!
i do a experiment as thus:using the default setting of CAM3 model,with the climate SST file, integrate 6 months,then there is a restart file and a initial file in 0006-01-01. then ,i run the model with climate SST file with two files sepatately for one month.then ,i compare the result of monthly average ,there has a severe difference. then ,i think the result of restart run is more believable than initial run .
now, i think give a anomaly to the land suface temperature of east asia. based the result above,I think it is more believable to change the "ts" variable in restart file than in initial file. Is this right?
Thans!
