Tutorial
======================

The CTDAS tutorial is written to provide some guidance for common tasks when running, extending, or modifying CTDAS for your own purpopes. 

.. warning:: It is not a basic course in data assimilation techniques, nor in the use of python, object-oriented programming, or UNIX. 

The descriptions assume that you are familiar with these. It also assumes that you have successfully compiled and 
run a transport model (usually TM5), that can serve as observation operator for your CTDAS runs. Instructions 
on how to obtain, compile, or write such a project are not included here. We refer to the :ref:`installation <installing>` section for 
further help with those steps.
