Dear Bi /all,

I am encountering a problem while changing SST in the experiment. First of all, there was no resetSST.f in Commons/tools directory, so I wrote it according to the document supplied.What is SST.RCM ? originally, I found all its value to be 273.15 K. I am simulating from 1 Jan to 30 Jun 2005. I am enhancing SST by 2 degree, but where to check whether it has increased or not ? (since there is no SST in any output). Otherwise, kindly let me know the procedure from begining how to change SST for my domain ?

Thanks

Shekhar
