\maketitle

\noindent \textit{In the following the italic text should be deleted in favor of the content that it describes, and subsection headings and table entries should be modified according to what is actually happening.  File should be named HALO-122 and saved and shared as a pdf, i.e., HALO-0122.pdf}

\section{Objective} 

\textit{Brief statement of purpose of flight and the extent it was intended to be coordinated with other platforms.  For HALO this likely would be 'Third Research Flight, Standard Circles and NTAS Buoy Excursion flown in conjunction with ATR and P3.' }

\section{Crew}  \textit{Note these have been adapted for HALO and should be changed for other aircraft}

\section{Synoptic Situation}  
\textit{A brief statement about the weather, any indication of cloud patterns or unusual features, brief discussion of other platforms with which the flight was being coordinated, if any, and how they related to the measurements.}

\textit{Text here should add qualitative overviews of what was selected as major flight elements.  For instance (below I make things up, just for illustration)}

\begin{description}
\item[Inter-calibration] Coordinated leg with ATR at certain region, indicating relative positions of plane, i.e., HALO overflight of ATR and TO along leg ... 
\item[Circle 1] Dropped twelve sondes with roughly even spacing, second sonde had difficulies.  All instruments working,  Shallow cloud field with no signs of precipitation, with more clouds and what appeared to be upper level out-flow associated with a flower in Eastern segment of circle.   Surface sea-state had strong coverage of whitecaps, aerosol loading exceptionally low.  
\item[Circle 2] Flower pattern moved into circle, cloud fraction substantially higher, with some precipitation in easter portion of circle.  Stratiform clouds were generally less than \SI{100}{\meter} and were consistently penetrated by lidar, mostly not detected by radar.
\end{description}

\section{Instrument Status} 

\begin{description}
\item[Radar] Started at 09:23, no anomalies 
\smallskip
\item[Sondes] 2nd Sonde of Circle 1 failed
\smallskip
\item[And so on]
\end{description}


\section{Figures} 
\textit{Here I would add figures, including photographs from flight-deck or cockpit to augment the other parts of the report.   The first figure should show the flight pattern geographically, the second should show flight levels versus time.  }
