aims and scope
The "waves school" will start on November 4 . It is intended for graduate students, post-docs, researchers, engineers or consultant that are dealing with ocean wave data of one form or another. The school will draw from the latest developments made possible by the IOWAGA, NOPP-waves, & Previmer, projects, and will benefit from the new (alpha) release of the WAVEWATCH III (R) version 4 from NOAA/NCEP.
Practical information: transportation, lodging ...
To prepare your stay in Brest during the ww3 training course, please find here all the information you need. For any question, send email to firstname.lastname@example.org
The morning lectures will be streamed in live on youtube. We will do 2 or 3 videos per morning, depending on the program.
The youtube links for live streaming will be given each morning on this page. It will also be possible to watch them after. A listing will be done here.

code and tools versions
Matlab or Octave
Easy reading of NetCDF 4 requires a Matlab version R2010b or more recent. Otherwise you may transform NetCDF 4 in NetCDF 3 and use a Matlab version that is as old as 2008.
Andres Sepulveda has started to adapt some of our basic matlab tools for *Octave* (an open source alternative to Matlab). You may contact him directly. To read NetCDF files in octave you the toolbox octcdf, which uses a recent version, 3.4.X at least.
For visualization of model output (maps, time series ...) and mesh generation we will use a runtime version of IDL that will allow you to use our Wave Visualization and Analysis Tool . Please follow the indications on that page.
For this you need to register in the Exelis website, wait for an approval of your account, and then download IDL. It might take a few days for you account to be approved, so please register as soon as possible.
Polymesh is an interface to the grid generation tool Triangle. You will find details here .
The WW3 code version to be used is alpha-4.12. An update has just been produced (October 25) to take into account quite a few bug fixes. It is distributed to all the participants present in Brest.
Due to US gov. shutdown, a temporary ftp site for download may be set up at Ifremer. However please read the licensing agreement and this clarification by NCEP .
Because it is an "alpha" version, there are still a few things that need to be ironed out ... thank you for your patience. On this page you will find a list of known issues, and we keep finding more...
The manual (which is contained in the package) is available here . The cover page says it corresponds to version 4.08 updated on August 25, 2011 ... This is not true! It does correspond to version 4.12 and was updated on July 2013, but it is still incomplete and your feedback will be very useful for completing it and making it easier to read. First time users of WW3 should we warned that it is written backwards, and you should start at chapter 5 if you want to install the model and work your way backwards towards chapter 1. If you just want to know what is in the model and what it does then you can start at chapter 1.
The program was designed in such a way that people that only use wave data and do not want to run a model can attend day 1 & 2 while the real brave geeks that actually want to install WAVEWATCH III and run the thing will be welcome to stay until late Friday.
