We have almost completed the section on installing HYSPLIT.  We covered it for a Windows PC, for an Apple Macintosh system, and for UNIX or LINUX. We reviewed what is actually installed, different subdirectories in HYSPLIT.  In this last part of installing HYSPLIT of section 1, we will do an exercise. In this first exercise, what you'll find is that in many of the subsequent sections, various files will be created and processed. So, for example, where would you find more information about the format of the trajectory endpoints file?  The hint here is to open the help file, the index.html file. Let's go ahead and do that.  Open windows explorer, go to the HYSPLIT4 directory, where HYSPLIT is installed, and go to the html directory and scroll down and find the index.htm file.  Then open that with your browser, and scroll down until you find the information about file formats.  There is a section right here under trajectories, we can click on file format and there can find out the actual format that's used to write the trajectory endpoints file.  Now we haven't discussed trajectories yet, but we did discuss how to use the help file and how to get information from there.  Also at the end of the index file for help, there's a whole section on file formats, all the different files that are used by HYSPLIT. We will be reviewing the use of these files in each section as is appropriate for the application.  This concludes section 1.
