Instructions:

1) Get the new version of Fuqing Superob Code from:

ftp://ftp.aoml.noaa.gov/pub/hrd/gamache/FuqingCode.tar.gz

2) Place tar file in a subdirectory of your choice...suggest either:
	/users/HRD/Fuqing

		or

	/users/HRD/FuqingCode

3) gunzip and untar the file

4) In subdirectory you will find the following files, which you should copy into 
/users/HRD
	rdsweep_to_so
	radials_split_sweeps_french
	radials_split_sweeps_noaa
	random_pick_so
	airborneVr2so_save.sh
	airborneVr2so.sh
	writeairborne
	ftpso

Make sure all 8 files above in /users/HRD have chmod set to 755.  This finishes your installation of the new code.


To run the code:

1) Start X11

2) Once started open a new terminal from the the "Applications" menu in X11.  This starts a terminal with the correct path (which includes /users/HRD within the path).

3) cd to the directory where you want to place the raw data.  I suggest:
	/users/HRD/SO/Raw

2) ftp (get) radials.txt.gz file corresponding to the flight leg from: 
	10.43.16.188:/home/hrd/radardata (on 43)
	10.42.16.187:/home/hrd/radardata (on 42)
	Note:  do not gunzip this file

3) Once that is done.  Run writeairborne by simply typing the word writeairborne within the X11 terminal.  It will then ask you very few questions:
	a) date, which should be entered in the exact YYMMDD format
	b) the start time for the Doppler radials, which will be in the 		name of the
		*radials.txt.gz file
	C) the end time for the Doppler radials, which will be in the name 		of the *radials.txt.gz file
	D) whether the aircraft has the NOAA or french antenna
	E) the 2 character suffix for the flight ID I1, I2, H1, or H2 (H 		corresponds to N42RF, and I to N43 RF, 1 or 2 corresponds 		to the number of the flight for that aircraft for the day).  		It will usually be 1, because normally 
		each aircraft only flies once a day.
	F) Next it will ask you if the working raw-data directory is 
		/users/HRD/SO/Raw, and if you answer yes the program end.
		If you answer no, it will ask you the name of the directory 		and then end
	G) The program will have made a new version of the script 			airborneVr2so.sh in the /users/HRD directory
	H) Invoke the script by typing "airborneVr2so.sh".  The script will 		then:
		gunzip the *radials.txt.gz file
		Make a directory called /users/HRD/SO/YYMMDD (where YYMMDD 
			are the year, month and day)
		Delete all files in the /users/HRD/SO/YYMMDD directory if 		there is a previous version of the directory
		Divide the data in the *radials.txt file into sweeps and 			place them in the directory /users/HRD/SO/YYMMDD
				(runs either radials_split_sweeps_noaa
				  or radials_split_sweeps_french)
		Gzip the *radials.txt file again
		Run a superobing program (/users/HRD/rdsweep_to_so) and
			place a separate superob file for each minute also 
			divided by fore and aft
		Cat all the superob data into one file and place in the 			directory /users/HRD/SO/SO or equivalent
		Randomly pick about half the data for superobing (by 
			running the program random_pick_so
		Gzip the three files now in /users/HRD/SO/SO
		Run a script that ftps the three gzipped data files to:
			ftp://ftp.aoml.noaa.gov/hrd/incoming/gamache
			(A script on nuwave will move the file to the 				 directory:
			 ftp://ftp.aoml.noaa.gov/pub/hrd/gamache/FuqingSO)
		Deletes the files in /users/HRD/SO/YYMMDD
		Moves the so files in /users/HRD/SO/SO to 
			/users/HRD/SO/SO/save.  You can ftp them to the
			/hrd/incoming/gamache directory again if you 
			need to
		End

This is a lot of writing and explanation for only a few commands by you.  In this version, you will see the ftp'ing at the end, and see if there are any problems.  If so you may need to ftp the files again from the directory /users/HRD/SO/SO/save
