- If the program loads and then hangs your PC causing you to have to reboot, there is probably not enough conventional memory available. See PC Memory Usage for more information.
- Documentation and definitions are in help files.
- The C-language program (cd_smos.c) which reads the CD-ROM data files is available from NCDC. This allows the user to develop their own software for accessing the data. See
NCDC CDROM Software and Snippets for more detailed instructions.

- Access software are NOT on CD-ROMs. For DOS users the software and data files are provided on diskette. They may also be downloaded here.
- Data records can be extracted in either a SHARP format or an FSL format. The SHARP format encodes the data in the NWS TTAA TTBB PPBB format. The FSL format is easier to read and displays the data in columns.
- SHARP format files can be read by SHARP software which will display graphs of a sounding. The SHARP software is written in BASIC. There are several limitations when using SHARP which may cause the software to abort when reading an extracted file. Frequently it may be necessary to EDIT the extracted file to either fix a NODE ID or to reduce the number of data levels. NCDC provides documentation which describes the complete functionality of SHARP.
- More detailed information about using this CD and accompanying software (including SHARP) is available
here.

- Access software executes on DOS only.
- Due to large conventional memory requirements this software probably will not run in a WINDOWS 95/98/ME environment, we recommend running in DOS version 6.x or earlier.
- If the program loads and then hangs your PC causing you to have to reboot, there is probably not enough conventional memory available. See PC Memory Usage for more information.
- The GTECCA program will extract only one storm track at a time.
- For those users when want to have access to all the storm track data values without have to extract them one storm at a time, call NCDC at (828) 271-4800 for assistance with ordering the data tape. It is available on exabyte, IBM 3480 cartridge, or 10-inch round tape.

- Due to large conventional memory requirements this software probably will not run in a WINDOWS 95/98/ME environment, we recommend running in DOS version 6.x or earlier.
- The first time you use the CD-ROM, make a directory on your hard drive to store the various data files required by the access software.
- From C:\, enter MKDIR GDS. (NOTE: You may use a different name than GDS)
- To run the access software, make sure you are in directory C:\GDS. If your CD-ROM drive letter is D, type
D:GDS D
- If the program loads and then hangs your PC causing you to have to reboot, there is probably not enough conventional memory available. See PC Memory Usage for more information.
- If your PC halts the access software load with the message "INCOMPATIBLE MEMORY MANAGER", the program EMM386.EXE in CONFIG.SYS usually has the wrong parameters to allow GDS to run. Program EMM386.EXE allows programs to use extended memory as expanded memory. To check the parameters: change your directory to C:\, Enter TYPE CONFIG.SYS | MORE
- Usually the command looks like -
. . . EMM386.EXE NOEMS
- If you remove NOEMS and change the command to read:
. . . EMM386.EXE 4096 M9 RAM
we have found this to be successful.
- Anything to the right of NOEMS should not be altered.
- To select data by Country/Region:
From Main Menu do the following:
- Select RETRIEVE/DISPLAY
- Select Filter Station Database
- Select Country/Region
Window: Country/Region
- Use Page Up/Page Down, Up Arrow/Down Arrow to locate country/region. DOUBLE CLICK to select. If "Total # Stations In Selected Area" is greater than 250, selection must be performed by LAT/LONG.
- Select OK
- Select RETRIEVE/DISPLAY
- Select Retrieve Data
Window: Build Station List
- Move stations to "Selected Station List" by:
A. Either select MOVE ALL,
B. or selectively move highlighted (blue) station(s).
- Select Begin Retrieval
Window: Retrieve DATA To DISK
- Verify Target Directory, Enter File Name For Station List.
- Select Begin Retrieval Data Retrieval SHOULD begin, returning to Main Menu when finished.
- To select data by Latitude/Longitude:
From Main Menu do the following:
- Select RETRIEVE/DISPLAY
- Select Filter Station Database
- Select Lat/Lon Square
Window: Lat/Lon Square
- Enter coordinates. For example, for Northern United Kingdom enter:
60 00 North Lat 009 00 West Lon
55 00 North Lat 000 00 West Lon
- Select Show Station Count. If count is OVER 250, redefine the Lat/Lon square.
- Select OK
- Select RETRIEVE/DISPLAY
- Select Retrieve Data
Window: Build Station List
- Move stations to "Selected Station List" by:
A. Either select MOVE ALL,
B. or selectively move highlighted (blue) station(s).
- Select Begin Retrieval
Window: Lat/Lon Square
- Enter File Name For Station List.
- Select Begin Retrieval. Data Retrieval SHOULD begin, returning to Main Menu when finished
- To perform a second selection for the United Kingdom, change coordinates in step 4 to:
55 00 North Lat 007 00 West Lon
49 50 North Lat 002 00 East Lon
Perform the other steps as shown above.

- No software is provided for data extraction or data manipulation.
|
- Extraction software should be included with COOP CD's purchased from NCDC. A FORTRAN source program and executable are provided for DOS users, and a FORTRAN source program for UNIX users is provided. The extraction software allows the user to extract one or more stations at a time specifying any or all data element codes. Data files can be written to diskette(s) or to a hard disk. Extracted data records are in the same format (402 bytes) as the input records.
- Extraction software may also be downloaded from
NCDC CD ROM Software and Snippets.
- NOTE: Occasionally data records in the CD data files have special control characters within data fields which cause sequential read operations in DOS to do strange things. The extraction software detects and replaces the invalid characters with either question marks or data codes for missing data so that subsequent use of the data will not cause read problems.

- For programs that experience lack of memory problems, NCDC recommends having 520K or more bytes of free conventional memory. To check your memory usage: from C:\, type MEM/C | MORE. This tells how conventional memory, high memory, and extended memory are used. To make more conventional memory available, the user must either move an application from conventional memory to high memory or eliminate a program that is loaded in conventional memory. Most of the programs are REQUIRED and cannot removed. Programs that we suggest as being possible candidates for removal is SMARTDRV.EXE and SETVER.EXE.
- Where are the instructions located for loading these programs? In CONFIG.SYS and AUTOEXEC.BAT. IF YOU DO NOT FEEL FAIRLY COMFORTABLE WITH MODIFYING THESE TWO FILES, SEEK ASSISTANCE BEFORE PROCEEDING. REGARDLESS, WE RECOMMEND CONSULTING YOUR DOS USER'S GUIDE. CONFIG.SYS and AUTOEXEC.BAT are located in C:\ (the root directory of your hard drive). FIRST, make a backup copy of each file:
COPY CONFIG.SYS CONFIG.BAK
COPY AUTOEXEC.BAT AUTOEXEC.BAK
(The extension on the output (.BAK) can be anything the user desires.)
- Optionally, you may want to print the two files for reference purposes.
TYPE CONFIG.SYS PRN
THEN, to edit a file enter:
EDIT CONFIG.SYS
Consult the DOS User's Guide for instructions on loading programs in high memory
EDIT AUTOEXEC.BAT
Type REM {space} at the beginning of a program to be deactivated
To save a file: Press ALT+FILE+SAVE
To exit a file: Press ALT+FILE+EXIT
