Hybrid of nowcast and definite Kp and ap values, simple ASCII format. The directory contains real time files, files with all values since 1932, year files, and files with ap and solar activity indices SN and F10.7

Definitive values, WDC ASCII format, monthly updated

Web Service API

Use a web service client to load the data directly into your program. Provide the start time and end time and the index you want to download. Here we provide program snippets for Python and Matlab.

To program the client yourself, use the following example URL:
'https://kp.gfz-potsdam.de/app/json/?start=2022-01-30T00:00:00Z&end=2022-02-02T23:59:59Z&index=C9&status=def'

Download Python Client

(time, index, status) = getKpData(starttime, endtime, index , ['def'])

  • 'starttime' and 'endtime': date format 'YYYY-MM-DD' or 'YYYY-MM-DDThh:mm:ss'
  • The date and time here always refers to the start time of the time interval of the index.
  • index selection ('Kp', 'ap', 'Ap', 'Cp', 'C9', 'Hp30', 'Hp60', 'ap30', 'ap60', 'SN', 'Fobs', 'Fadj')
  • 'def' optional, output of definitive values only (only for Kp, ap, Ap, Cp, C9, SN)
