Solar wind inputs 
Time-dependent solar wind plasma and magnetic field inputs.
 Solar wind inputs are derived from a single spacecraft usually 200 R_E upstream of the sun-ward (front) simulation box boundary.

 User-submitted data may be from any source or made-up. ACE-realtime

 0 -1 1
Bx 
Sun-Earth component of solar wind magnetic field.
 Bx is usually held constant (zero or average of observed values) to conserve div.B at the front boundary. Alternatively, oblique phase fronts can be assumed that update solar wind conditions along those fronts throughout the front boundary. Bx is then approximated as a linear combination of time dependent By and Bz. nT -5 -100 100
By 
Dawn-dusk component of solar wind magnetic field.
 nT 0.5 -100 100
Bz 
North-south component of the solar wind magnetic field. B_z is most important magnetic field component to drive or inhibit geomagnetic activity. Other components play a role in connection with the orientation of the Earth's dipole field.
 nT 5 -100 100
Vx 
Sun-Earth component of solar wind velocity.
 Low solar wind speed (less than 200 km/s in magnitude) usually indicates poor statistics in the solar wind plasma measurements. km/s -433.4 -3000 -200
Vy 
Plasma velocity in dawn-dusk direction.
 The orbital velocity of Earth (about 29 km/s) is usually neglected. km/s 0 -500 500
Vz 
Solar wind plasma velocity in north-south direction.
 km/s 0 -500 500
N 
Solar wind plasma density.
 Mass density described in terms of number of protons per cubic centimeter. AMU/cm^3 14.3 0.1 100
T 
Solar wind plasma temperature.
 Derived from observed distribution of solar wind particles. Can fluctuate widely when density N is at or below 1 AMU/cm^3. K 80400 10000 2000000
SW density floor 
Lowest value of N applied during pre-processing of solar wind input data.
 The density floor in the solar wind varies by magnetosphere model and it's numerical stability. A similar floor may be imposed inside the magnetotail lobes where the density may drop lower than in the solar wind. AMU/cm^3 0.1 0.1 2.5
