% Copy-and-paste your following abstract text into "Abstract" field of the web form:
%

This is a template of how to format an Abstract for the COSMO~/ CLM~/ ICON~/ ART User Seminar 2017.
We accept plain text abstracts, which might contain \LaTeX\xspace commands and formulas.
The title, the name(s) of author(s), their affiliation(s) and the text of the abstract
have to be input into our web form.

To use \LaTeX\xspace commands, the best is to prepare your abstract within this template
without adding any further \LaTeX\xspace packages. Do not use sections, figures, 
fancy formatting or own macros, e.g., shortcuts for mathematical operators etc.
If you can process this document successfully through \LaTeX\xspace, then it will also work
in our system.

Author(s) and Affiliation(s) should be specified in exactly the above way as comma-separated lists.
In the \texttt{\textbackslash author\{\}} command, use numbers in brackets after each author's name
to indicate different affiliations. Authors with same affiliation should have the same number.
In the \texttt{\textbackslash affil\{\}} command, the affiliation(s) should be listed 
with the affiliation number in brackets first, followed by the affiliation name,
a comma, the next affiliation name, and so on.

Once you are done, please \textbf{copy-and-paste} the content of the above
\texttt{\textbackslash title\{\}} command into the ``Title of abstract'' field
of the web form. Similarly, copy-and-paste the content of the \texttt{\textbackslash author\{\}}
command into the ``Authors(s)'' field and the contents of the \texttt{\textbackslash affil\{\}}
command into the ``Affiliation(s)'' field.

Finaly, copy-and-paste all your text between \texttt{\textbackslash maketitle} and
\texttt{\textbackslash end\{document\}} into the ``Abstract'' field.

Thank you very much and see you in March!

Ulrich Blahak
