Global geomagnetic index Kp

Kp and its related indices (ap, Ap, Cp) are widely used in ionospheric and magnetospheric studies and are generally recognized as indices measuring worldwide geomagnetic activity. The IAGA-97 Resolutions #5 and #6 recognize the value of preserving the uniqueness of the official IAGA indices and the importance of geomagnetic activity indices for characterization and prediction of a wide range of geomagnetic phenomena. The Kp and its related indices maintained at GFZ Potsdam and NGDC.

Specific details of Kp and its related indices are given on the following websites.

Provision of Kp index data for AFFECTS

NRT data and data of the last month required for different FSI processing modules are internally provided in the FSI. Automatic processes are established, downloading the corresponding files (see below) from the website and ftp servers and storing them on the FSIPickup Point. The Pickup Point inhabits the input data for the FSI. All data stored there is then provided to the FSIprocessing modules.

For the processor development and scientific purpose, the geomagnetic indices can be directly downloaded from the websites and ftp servers given below.
