Using monotone for distributed ROMS development

Here is how it is done. First get monotone, I would suggest getting one of the compiled binaries, since compiling does not appear to be trivial. Read on for an example of how to use this program to link to a ROMS project. This tutorial is based heavily on the turorial available on the monotone site.

Shelf break front simulation

Here is a sample cross-section from an idealized shelf break front simulation. The contours are salinity, the colorfill velocity.

Version Control Systems Comparison

Hmmm. What are the differences between all those different version control systems?

Parameter space exploration in ROMS

Often, I find that I want to run roms over some set of parameters. The best way to do this is to make critical parameters dependent on the USER parameters in the roms.in file. I have written a program in python which does just this, automatically.

Changed NetCDF fixed dimension to record dimension

Sometimes it is neccissary to change a fixed length dimension to a record dimension (an UNLIMITED) dimension. There is no straightforward way to do this, unfortunately, but I have found this relatively simple hack to be useful:

First make a new NetCDF file that contains only one record dimension, the same name as the dimension you wish to change, say time. I do this in MATLAB like this

f = nc('rec_dim.nc','noclobber');
f('time') = 0;
close(f);

Now, simply append the information in the NetCDF file using ncks (part of the nco package), like this

ncks -A orig.nc rec_dim.nc

You can now delete orig.nc. (You could also overwrite the origional directly).
