% \begin{abstract}
% \noindent This package introduces commands to generate professional meteorological symbols with vectorial quality. As of \today, these include: oktas (\zerookta, \oneokta, \twooktas, \ldots), cloud genera (\cirrus, \cirrostratus, \nimbostratus, ...), and C$_\text{L}$--C$_\text{M}$--C$_\text{H}$ cloud codes (\clIII, \cmVI, \chIX, \ldots). This package essentially introduces a new font in which each symbol is assigned to a glyph, which can then be called individually from \LaTeX\ documents via dedicated commands.
% \end{abstract}

%
% \section{Why \textsf{metsymb} ?}
%
% The creation of this package was motivated by the fact that in 2021, there were no dedicated Unicode elements for \href{https://en.wikipedia.org/wiki/Okta}{okta} and \href{https://cloudatlas.wmo.int/en/abbr-and-symbols-of-clouds-table-genera-species.html}{cloud genera} symbols. To the best of my knowledge, no \LaTeX\ package provides a uniform set of these symbols either\footnote{If you know of one, please let me know and I shall list it here !}.\\
%
% \noindent This package is a direct attempt to remedy to this unfortunate state of affair. Individual symbols are designed using TikZ\footnote{\url{https://www.ctan.org/pkg/pgf}}. They are then bundled into a dedicated font with FontForge\footnote{\url{https://fontforge.org/en-US/}}. Individual glyphs of this metsymb font are then tied to dedicted \LaTeX\ commands via this package.\\
%
% \noindent One key element of the metsymb symbols is that they are \textbf{designed using explicit (mathematical) TikZ commands}. This evidently helps to maintain a uniform look between the symbols, but also --and perhaps more importantly-- it ensures that each symbol can be faithfully reproduced with different software in the future (should the need arise).
% \section{Usage}
%
% Using the \textsf{metsymb} package is straightforward. By importing it via a not-so-surprising \texttt{\textbackslash usepackage\{metsymb\}} in the preamble of your documents, you will gain access to the commands listed in Tables~\ref{tbl:oktas} to \ref{tbl:clcmch}.

% \subsection{Using \textsf{metsymb} with \textsf{matplotlib}}
%
% \noindent \textsf{metsymb} can be used to include meteorological symbols inside Python plots, provided that the use of a system-wide \LaTeX\ installation is enabled via the setting \texttt{text.usetex} in your rcParams\footnote{\url{https://matplotlib.org/stable/tutorials/text/usetex.html}}. In fact, the assembly of a dedicated vectorial font to store the \textsf{metsymb} symbols\footnote{instead of a simpler TikZ approach, \href{https://tex.stackexchange.com/questions/610992/creating-new-symbols-with-full-font-metrics-and-vector-quality}{for example}} is directly motivated by the fact that \textsf{matplotlib} \href{https://stackoverflow.com/questions/68769147/tikzpicture-cropped-from-dvi-when-used-in-matplotlib-plt-text}{requires proper font metrics} to include symbols in Python plots.\\
%
%\noindent The following minimal working example, stored in \texttt{metsymb\_mwe.py} inside the \textsf{metsymb} Github repository, illustrates how one can couple \textsf{metsymb} and \textsf{matplotlib} (see Fig.~\ref{fig:mwe} for the result):
%
% \lstinputlisting[language=Python]{metsymb_mwe.py}
%
% \noindent where \texttt{metsymb\_mwe.mplstyle} contains:
%
% \lstinputlisting[language=Python]{metsymb_mwe.mplstyle}

%
% \section{Code development and bug reports}
% The \textsf{metsymb} package is being developed inside a dedicated Github repository under the MeteoSwiss organization, located at: \url{https://github.com/MeteoSwiss/metsymb}. User contributions are welcome and will be examined in details. So are bug reports and suggestions for new symbols, which are best submitted as \textit{Github Issues} directly on the code's repo at: \url{https://github.com/MeteoSwiss/metsymb/issues}
%
% \section{License and copyright}
% The copyright (2021-2023) of \textsf{metsymb} is owned by MeteoSwiss. The code, originally written by FrÃ©dÃ©ric P.A. Vogt, is released under the terms of the BSD-3-Clause License, available at \url{https://opensource.org/licenses/BSD-3-Clause}.
%
% \section{Ackowledgments}
% The following resources proved immensely useful to assemble the first version of this package:
% \begin{itemize}
% \item  \textit{How to Package Your \LaTeX Package}, Scott Pakin (2015): \url{https://mirror.foobar.to/CTAN/info/dtxtut/dtxtut.pdf}
% \item The FontForge documentation, and in particular the \textit{FontForge and TeX} article: \url{https://fontforge.org/docs/techref/PfaEdit-TeX.html}
%\item The \textit{\TeX\ font errors: Cheatsheet}: \url{https://texdoc.org/serve/tex-font-errors-cheatsheet/0}
% \end{itemize}
%
% \noindent Several StackOverflow users also proved extremely helpful when building \textsf{metsymb}, in particular:
% \begin{itemize}
% \item those that provided clarifications and help \href{https://tex.stackexchange.com/questions/610992}{in this post}, \href{https://stackoverflow.com/questions/68769147}{in that post}, and \href{https://tex.stackexchange.com/questions/611746}{in that other post}.
% \end{itemize}
%
% \noindent Thank you also to jklymak and anntzer.lee from the \textsf{matplotlib} discourse community for their clarifications in \href{https://discourse.matplotlib.org/t/tikzpicture-cropped-from-dvi-before-ingestion-in-figure-via-plt-text/22249}{this post}.

% \section{Font table}
%
% The complete font table for \textsf{metsymb}, generated via the command \texttt{pdftex testfont} with the \texttt{\textbackslash sample} call, is visible in Fig.~\ref{fig:testfont}.

% \section{Implementation}
%
% The \textsf{metsymb} package very simply defines new commands to fetch individual glyphs from the \texttt{metsymb} font. As such, its \LaTeX\ side is rather simple.
