The Space Weather Prediction Center (SWPC) provides several Advanced Composition Explorer (ACE) instrument data sets for use as real-time and historic measurements of the solar wind. This differs from the ACE scientific data, which is available at a greater latency from CDAWeb. Information about these data sets can be found at the SWPC ACE Solar-Wind page.
EPAM is the Electron, Proton, and Alpha Monitor onboard ACE.

The Space Weather (SW) platform encompasses space weather indices that may be found across a variety of platforms. Many of the remote centers that provide these data sets include multiple types of data in each file. From :pypysatSpaceWeather version 0.1.0, the remote information is separated by :pypysat.Instrument and saved into appropriate files. For example, the definitive Kp data from the German Research Centre for Geosciences at Potsdam (GFZ) will also download Ap and Cp data files.
AE is an auroral electrojet index that reflects the level of magnetic deflection in the auroral zone due to the difference between the eastward and westward electroject currents at Earth. Real-time predictions (last 96 hours) are provided by LASP.
pysatSpaceWeather.instruments.sw_ae
AL is an auroral electrojet index that reflects the lower envelope, the negative peak of the electroject currents at Earth. Real-time predictions (last 96 hours) are provided by LASP.
pysatSpaceWeather.instruments.sw_al
AU is an auroral electrojet index that reflects the upper envelope, the positive peak of the electroject currents at Earth. Real-time predictions (last 96 hours) are provided by LASP.
pysatSpaceWeather.instruments.sw_au
Ap is a geomagnetic index that reflects the magnitude of geomagnetic disturbances at Earth but unlike Kp uses a linear scale. Historic, recent (last 30 days), and forecasted values are available from GFZ and the SWPC Forecasts page.
pysatSpaceWeather.instruments.sw_ap
apo is a linear (half)-hourly, planetary, open-ended, geomagnetic index that reflects the magnitude of geomagnetic disturbances at Earth. It is like Ap but does not have an upper limit. Values from 1995 onwards are available from GFZ.
pysatSpaceWeather.instruments.sw_apo
Cp is a derivative geomagnetic index that provides a qualitative estimate of the overall level of magnetic activity for the day. The C9 index provides the same information on a scale from 0-9 instead of 0.0-2.5. Historic values are available from GFZ.
pysatSpaceWeather.instruments.sw_cp
The Disturbance Storm Time (Dst) Index is a measure of magnetic activity associated with the ring current. The National Geophysical Data Center (NGDC) maintains the current database from which the historic Dst is downloaded. LASP performs the calculates and provides the predicted Dst for the last 96 hours. You can learn more about the Dst Index at the WDC Kyoto Observatory page.

F 10.7^^^^^^^^^^^^^^^^
F 10.7 is the 10.7 cm radio solar flux (measured in solar flux units, sfu) [Cortie 1912]. Historic indices, real-time indices, and forecasted indices are available from LASP and the SWPC F107 page.
pysatSpaceWeather.instruments.sw_f107
Solar flares have been monitored for decades and the data has been compiled into standard measurements from different data sets. Historic indices, real-time indices, and forecasted indices are available from SWPC.
pysatSpaceWeather.instruments.sw_flare
Hpo is a (half)-Hourly, planetary, open-ended, geomagnetic index that reflects the magnitude of geomagnetic disturbances at Earth. It is like Kp but does not have an upper limit. Values from 1995 onwards are available from GFZ.
pysatSpaceWeather.instruments.sw_hpo
Kp is a geomagnetic index that reflects the magnitude of geomagnetic disturbances at Earth. Historic, recent (last 30 days), and forecasted values are available from GFZ, and the SWPC Kp page.
pysatSpaceWeather.instruments.sw_kp
The core-to-wing ratio of the solar MgII line is a proxy for solar chromospheric variability. It has been used to extract a precise measurement of solar activity at Earth. The two data sets provided by LASP together provide index values from 1978 through 2020.
pysatSpaceWeather.instruments.sw_mgii
Polar cap indices have been developed to provide information about high-latitude conditions and inform ionospheric space weather models. Currently, this :py~pysat._instrument.Instrument provides absorption predictions from SWPC.
pysatSpaceWeather.instruments.sw_polarcap
The solar mean field provides a measure of of mean solar magnetic field using full-disk optical observations of the iron line. The first observations were made at Stanford by Scherrer et al..
pysatSpaceWeather.instruments.sw_sbfield
The Sunspot Number (SSN) is one of the oldest continuously measured solar indices. Currently, this Instrument provides preliminary and daily values from SWPC (for example, here is the forecast page).
pysatSpaceWeather.instruments.sw_ssn
Geomagnetic storm predictions are provided by SWPC for global, high-latitude, and mid-latitude regions. SWPC uses the NOAA SW scales, which are explained here.
