Reprocessing Digisonde data with ARTIST 4 software

24Mar1999
 

This HOWTO describes the process of using ARTIST4 to re-process old Digisonde data. Please email comments and corrections to: Bullett@plh.af.mil
 

Requirements: OS: Windows 95 /98 /NT 4.0  CPU: Penitum class or better  RAM: 32MB  Disk: 500MB+ for output files  CD-ROM reader  Network access is a major plus

1. Read the following documents:


http://ulcar.uml.edu/~iag/artist-4.htm
http://ulcar.uml.edu/~iag/Personalizing-Artist4.html
 

2. Obtain the latest copy of Artist4 from the UMass Lowell FTP site:


ftp://ulcar.uml.edu/Digiuser/Artist4upgrade/LatestExecutablesARTIST4.ZIP
A valid username and password are needed.
 

3. Un-zip the ARTIST4.ZIP file into a directory. I'll assume it's D:\ARTIST4
4. Create an outgoing file directory for the scaled data. I'll assume it's D:\SCALED
5. The primary file Artist4 needs is a configuration file, typically called ARMENU.ONL. This file is site-specific. Station Info can be obtained at: http://ulcar.uml.edu/framesn.htm

 

 

Best Approach:

a) Obtain a copy of the ARMENU.ONL file for the station you want to re-process. This should have all the necessary site specific information.
b) Start with a generic ARMENU.ONL file. You need to provide all the critical site specific information.
 

6. Edit the file to ensure the following entries are valid.

 

 

Items 101, 102, 307, 309, 310, 007 are CRITICAL.

In particular:
 

• Item 007 must be <4> to re-process data. It is normally set to <1> for real time operation at the sounder. The other items are nice to have set correctly.
• Items 309 and 310 must be the directory you want scaled data to go, i.e. D:\SCALED
The other displayed items will vary from station to station, but they are not critical.

ARTIST Disk Write Options
        1 Don't Write on Disk
        2 Write ART & ION files on Disk
        3 Write ART files on Disk
        4 Write SAO & ION files on Disk
        5 Write SAO files on Disk
        10 Write ART, SAO & ION files in Disk
*041 < 10 >

Write ART and/or SAO files here:
*309 < D:\SCALED\ >

Write ION files here:
*310 < D:\SCALED\ >

ARTIST-4 reads input DATA from here:
*311 < >

Enter network drive and/or path to which ARTIST and MMM files will be copied.
If not desired, leave the field blank.
*312 < >

7. Save the file to something station-specific, such as WALLOPS.ONL
8. Mount the CD-ROM with the Digisonde data to be re-scaled. I'll assume it's drive E:\
9. Call up a command prompt
10. Run the Artist4

cd D:\ARTIST4
ARTIST4 WALLOPS.ONL

11. The program will prompt you for a filename, or wildcard, specifying the files to be processed. For all the files on the CD-ROM, type E:\*.*
12. The program will ask about time search. Enter 1 for no search
13. The Artist4 will start processing ionograms.
14. When the program is finished, various files *.ART, *.SAO, *.ION will be in the output directory D:\SCALED If the input files were the standard 1 file per day, the output files will be the same way.
