Instrument details
Acronym MAG (DSCOVR)
Full name Magnetometer
Purpose Observation of the vectorial magnetic field associated to the solar wind
Short description Description not available. Presumably, triaxial fluxgate magnetometers (boom mounted). 8 dynamic ranges: ± 4 nT; ± 16 nT; ± 64 nT; ± 256 nT; ± 1024 nT; ± 4096 nT; ± 16,384 nT; and ± 65,536 nT. Resolution ± 16 nT @ maximum of dynamics. Accuracy 0.006 nT
