==== PlasMag ====
The Plasma-[[Magnetometer]] (PlasMag) measures [[solar wind]] for [[space weather]] predictions. It can provide early warning detection of solar activity that could cause damage to existing satellite systems and ground infrastructure. Because solar particles reach {{L1}} about an hour before Earth, PlasMag can provide a warning of 15 to 60 minutes before a [[coronal mass ejection]] (CME) arrives. It does this by measuring "the magnetic field and the velocity distribution functions of the electron, proton and alpha particles ([[helium]] nuclei) of solar wind".<ref name= "noaa_plasmag"/> It has three instruments:<ref name=noaa_plasmag>{{cite web|title=NOAA Satellite and Information Service: Deep Space Climate Observatory (DSCOVR): Plasma-Magnetometer (PlasMag) |url= http://www.nesdis.noaa.gov/DSCOVR/pdf/DSCOVR%20-%20PlasMag%20Instrument%20Info%20Sheet.pdf| publisher=NOAA|access-date= February 10, 2015|url-status= dead| archive-url= https://web.archive.org/web/20150210181113/http://www.nesdis.noaa.gov/DSCOVR/pdf/DSCOVR%20-%20PlasMag%20Instrument%20Info%20Sheet.pdf|archive-date=February 10, 2015}} {{PD-notice}}</ref>
