Courant number Tool

Thanks

Steve

Hi John, Sorry to take so long to get back on this, got sidetracked on another project ... Anyway I did get ncei_2roms.m to work. Here is a list of the changes I made. I only worked on the NAM and NARR sections since I didn't use GFS data. Nor did I make any changes to Matlab "ncread" part...

Re: wind vector direction in NAM and NARR data

John W,

Did nomads_2roms.m end up being named ncei_2roms.m?

Thanks,
