\subsection {PTRACERS Package} \label{sec:pkg:ptracers} \begin{rawhtml} \end{rawhtml} \subsubsection {Introduction} \subsubsection {Equations} \subsubsection {Key subroutines and parameters} Run time parameters set in {\bf data.ptracders}: $\bullet$ {\bf PTRACERS\_Iter0} which is the integer timestep when the tracer experiment is initialized. If {\bf nIter0} $=$ {\bf PTRACERS\_Iter0} then the tracers are initialized to zero or from initial files. If {\bf nIter0} $>$ {\bf PTRACERS\_Iter0} then tracers (and previous timestep tendency terms) are read in from a the ptracers pickup file. Note that tracers of zeros will be carried around if {\bf nIter0} $<$ {\bf PTRACERS\_Iter0}. \\ \subsubsection{PTRACERS Diagnostics} \label{sec:pkg:ptracers:diagnostics} {\footnotesize
