I originally wrote CARI-7 to read the NGDC files, which NOAA stopped updating in 2018.
The batch scripts in this folder use global Kp index data files in SWPC format to create similar files in old NGDC format. 

This conversion is needed to acount for changes in SWPC versions of the file since 2018. For example,  in 2022 NOAA changed from (N, N+, or N-) to (N.**[decimals for fractional Kp]). 

To use the scripts: 

1. Run CONVERT.BAT from the CMD prompt. See the notes in the scripts for details of how it works. You will need the year and quarter you want kp data for from SWPC and need to decide on a filename for the results. 

2. Append the reformatted data to the end of the file KP_INDEX\KP_INDEX.TXT . 

Do not worry about the lack of Ap data for recent dates. 
CARI-7 and 7A do not use the Ap data. The Ap characters are only placeholders to ensure correct reading because of the legacy format.
