We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

The Deep Space Climate Observatory (DSCOVR), a partnership between NASA and NOAA, makes it possible to monitor solar wind activity in real time. Having the ability to identify space weather events early is critical to protecting public infrastructure systems such as power grids, telecommunications, aviation, and the Global Positioning System (GPS), all of which can be significantly affected by solar storms (also known as geomagnetic storms).
Data delivered by DSCOVR can provide warnings to forecasters 15 to 60 minutes before solar storms reach Earth. This data also helps forecasters improve their predictions of where a geomagnetic storm may cause disruptions.
Type
Solar/Space Observation Satellite
Launch
Feb. 11, 2015
Objective
Real-time solar wind observations to provide early warnings about geomagnetic storms
Get DSCOVR Data for PlasMag at NOAA
On Oct. 28, 2015, NASA officially handed over control of DSCOVR to NOAA’s Space Weather Prediction Center. Visit NOAA to learn more about DSCOVR and where to download data from the Plasma-Magnetometer (PlasMag).
