Current SST/Sea Ice Boundry Conditions

[boyle5@llnl_gov]

Are there any plans to maintain a current SST/sea ice data set ?
i.e. beyond the 1949 - 2001 data that is distributed.

We can only provide the tools that are used to produce the sst/ice dataset. I just had a conversation w/ Dennis Shea about the datasets we use as input to those tools. He plans to make current versions of that data available shortly, but tells me he's made a change to the time coordinate info in the file. I will make the necessary changes to CAM's tools and make an updated version available. Note that the CAM tools start from the Shea/Hurrell dataset and do both spatial interpolation as well as apply an algorithm from Karl Taylor to adjust the monthly mean values so that time averaging of linearly interpolated data reproduces the time mean from the original dataset.

Brian,
Thanks for the reply.
What are the routines to which you are referring when you mention 'tools'?
There is a directory : $CAM_HOME/cam1/models/atm/cam/tools in the CAM3.1 distribution are these the codes you mean? I have never been able to figure out what they do - is there any documentation?

In any case, this just pushes the question up to Dennis. Is his data source going to be available and kept (within reason ) current?

Hi Jim,

Yes, the tools for the sst and ice datasets are in the tools/icesst/ directory. The only documentation is the README file in that directory. I have done some work to make these tools easier to use, and as I mentioned will probably need to tweek them somewhat to accomodate the changes Dennis has made to the input datasets (which are are 1x1 degree resolution). My understanding from Dennis is that he plans to update the input datasets monthly.

Brian,

This is very encouraging. A monthly update is much better than I would have anticipated.

Thanks

Hi,
I've been trying to use the tools you mentioned. I got the following error as I execute "gmake".
Could you please help? Thank you very much.
