HIRLAM newsletter 54
Thanks a lot to everyone who sent contributions!
There are many interesting and useful papers that we want to make available as soon as possible. The printing process will take quite some time. Therefore the papers are put on HexNet (for HIRLAM members only) the way I received them from the authors. Please be aware that during the preparation for printing the layout and page numbers of the articles change, and also editorial changes to the text are possible.
Please note that not all papers are available on HexNet. The articles of which the authors informed me that they provided a preliminary version will be made available as soon as I get the final version.
The planning for the printing process is as follows. Review of the articles until beginning of September 2008. Processing by studio in September and October. I hope the Newsletter can be printed by the end of October 2008.
Issue of March 2008, for the moment available as one rather big pdf document (21 MB)
