\section{General Points}

This document describes programming \textit{abbreviations}.
Abbreviations are quite general: Any shortened
form of a word, phrase, or concept is an abbreviation.
Hence, abbreviations can be acronyms, initialisms, or nicknames.
Concise abbreviations for variable names are especially important
because they help make a program become self-documenting and thus
easier to maintain.
Consistent abbreviations across programs are important because then
whole suites of code can be updated an improved in a more modular
fashion. 
An alternative method of naming variables is the \trmdfn{Hungarian
notation} method originated by Charles Simonyi of Microsoft
\url{http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvsgen/html/hunganotat.asp}

\subsection{Abbreviations}
Abbreviations are usually used for variable names in a program.
Naming a variable appropriately often speeds up programming by
reducing the introduction of bugs to the program, and by making future 
maintenance easier.
An effective abbreviation has a number of desirable qualities.
\begin{itemize}
\item Concise
\item Unambiguous
\item Easy to remember
\item Distinct from English
\end{itemize}

Here are some guidelines which help in creating abbreviations with
these qualities: 
\begin{enumerate}
\item A common acronym, if it exists, is preferable to creating a new
abbreviation (e.g., \verb'SWCF').
\item Abbreviations which do not contain common letter combinations of the
English language are much easier to program.
Searching and replacing uncommon letter combinations lessens the risk
of corrupting plain text and comments in the program. 
For example, using \verb'flx' rather than \verb'flux' saves only one
letter, but makes code maintenance much easier. 
\item Phonetic abbreviations are often superior mnemonics.
Use, e.g.,\verb'nvr' rather than \verb'env' for ``environment''.
Phonetic abbreviations make it easier to use consonants, which are
better than vowels in abbreviations.
\item All things being equal, three letter abbreviations, or groups of
them, are best.
Three letters are easy to remember yet there are enough permutations
to abbreviate almost atomic concept into a three letter abbreviation.
\item Single letter abbreviations, e.g. ``\verb't' = temperature'',
are always a mistake. 
It is nearly impossible to perform a quick search or
search-and-replace on a single letter variable.
\item Sometimes an abbreviation is an acronym but is not capitalized.
Capitalize the abbreviation when it is common (e.g., \verb'SWCF'), but
leave it lowercase when it is uncommon (e.g., \verb'mpc'). 
\end{enumerate}

\subsection{Variable Names}
Use underscores to aggregate abbreviations into longer groups which
compose a variable name.
Underscores are easier to proofread than the X-style capitalization 
method, e.g., \verb'flx_bb_dwn_sfc' vs.\ \verb'FlxBbDwnSfc' or
\verb'FluxBroadbandDownSurface'.  
Variables names constructed in this manner have the desirable property
that, when they are alphabetized, related variables are grouped
together. 

\subsection{Definitions}
Often an abbreviation is used to keep a quantity distinct from a
related but distinct quantity. 
In these cases the abbreviations are called \textit{antonyms}.
In the list, the antonym of a given definition is indicated by
``{\textit ant.}''.
Occasionally an abbreviation has a synonym, too.
In the list, the synonyms are indicated by ``{\textit syn.}''.

The abbreviation is followed by the definition.
In some cases the definition has multiple related meanings---these are
separated by commas, e.g., ``\verb'abs' = absorption, absorbed, absorbing''.

In a few cases, the definition has multiple distinct meanings---these
are separated from one another by ``or'', e.g., 
``\verb'aer' = aerosol, aerosol-laden (turbid), or aerodynamic''.
