How does the Space Weather Prediction Center calculate the Kp index?

The Space Weather Prediction Center calculates near real-time estimates of the Kp index using eight of the thirteen official Kp network stations.

What is KP data used for?

The Kp data is used to calcuate the ap, Cp, and C9 data. It is used from the end of the GFZ nowcast and followed by the 45-day predictions below. Contains: 45-day forecast of daily ap and F10.7Adj. Kp is estimated from ap and F10.7Obs is calculated from F10.7Adj. Contains: Monthly ISN for approximately 18.5 years.

Does NOAA/SWPC estimate KP?

Since NOAA/SWPC uses a subset of the official network for estimating Kp, a similar limitation applies and therefore the values on the NOAA/SWPC website should be considered to be estimates of the Ap-index. The value of this estimated Ap index is reported in NOAA daily and weekly summaries of geophysical activity.

What is planetary Kp index?

The planetary Kp-index is a globally averaged indicator of the worldwide level of geomagnetic activity. The official Kp index is derived by calculating a weighted average of K-indices from a predetermined network of geomagnetic observatories, the official Kp network.

What is the estimated 3-hour planetary Kp-index?

The Estimated 3-hour Planetary Kp-index is a preliminary Kp-index derived at the NOAA Space Weather Prediction Center using minute by minute data from a number of ground-based magnetometers that relay data in near-real time. These observatories are located in the United States, Canada, the United Kingdom, Germany and Australia.

How does SWPC monitor Kp index?

Using minute-by-minute station K-indices, SWPC monitors the estimated Kp index in near real-time and issues alerts when thresholds are crossed. A complete description of SWPC alerts, watches and warnings are on the web pages: www.swpc.noaa.gov/alerts/.
