Data assimilation docs

Last year I finished my PhD (you can read my dissertation here, in Spanish) and now I finished documenting the technical part of my data assimilation experiments into a website.

The website compiles a series of examples, tutorials, scripts and in general a comprehensive documentation around the GSI system V3.7 - EnKF V1.3. It focus on the use of GSI as a observation operator along with the EnKF version. It covers everything you need to know from how to deal with observations (in bufr format), how to configure the system to assimilate conventional and radiance observations to how to read and interpret GSI outputs.
