REORDER

You can edit or write scripts using the text editor in UNIX. Just click on the text editor button on the bottom of the screen. These files can be named anything. I like to use a format that includes the date such as: reo980813 (year, month, day) or 980813r for example.

Use this exact format for the REORDER script file.

Notes:

INPUT: Input .UF file here when you get it.

OUTPUT: This is what you name the .ced file that this program creates. Name it whatever you want. Again, I like to keep things consistent with dates.

RLONGITUDE/RLATITUDE/RALTITUDE: Radar coordinates. IMPORTANT! The coordinates given above are not CHILL’s coordinates. Be sure to find out what those are!

GLONGITUDE/GLATITUDE/GALTITUDE: Same values as radar coordinates. These are the grid locations.

XMIN/MAX/SPACING/RADIUS: As the name implies, it is the x coordinates you want to plot at a spacing of your choice. Find this out from original radar data by using RDSS or SOLO. Same for Y and Z coordinates.

WEIGHTING FUNCTION: Use CRESSMAN unless otherwise stated.

Ignore AZRADUIS, ELRADIUS, and RGRADIUS, unless stated otherwise. Comment these out ( ^).

FIELDS: Use the ones stated by professor. Comment the rest out. These include:

Time: TI, TIME

Horizontal Reflectivity: DZ,ZH

Differential Reflectivity: ZD,ZD

Linear Depolarization Ratio: LD, LD

Differential Propagation Phase Shift: KD,KD

Cross-Correlation Coeffiecient: RH,RH

Power: DM,DM

Spectral Width: SW,SW

Velocity: VE,VE

PhiDP: PH,PH (What the actual radar measures)

Azimuth: AZ

Elevation: EL

Range: RG,RANGE

Comment out EARTHRADIUS, QUALITY, UNFOLD, EXPERIMENT, and INSTRUMENT.

Be sure to enter the correct start and stop times. These can be obtained form the .UF file on SOLO or RDSS.

Be sure to leave SPANVOLUMES and quit as is.

Once the script file is set, REORDER can be run. At the prompt, type:

qreou (name of reorder script)

After the program is finished running, a .ced file as named above should be present in your folder. This is the input to Cedric.
