    47 Since November 2008, the parameter 77 (deta/dt) is stored in ``MARS`` on full model levels. ``FLEXTRA``/``FLEXPART`` in its current version requires ``deta/dt`` on model half levels, multiplied by ``dp/deta``. In ``flex_extract``, the program ``CONVERT2`` assumes that this parameter is available if the ``CONTROL`` parameter ``ETA`` is set to 1.

    4949It is recommended to use the pre-calculated parameter 77 by setting ``ETA`` to 1 whenever possible.
