Solar Wind Settings 
Solar Wind Settings which include 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.
Name Description Caveats Units Default Value or Actual Value Valid Min Valid Max
solarwind 
Flag indicating whether solar wind data are 'const' (constant) or 'var' (variable).
 var
sw_source 
Name of the spacecraft or data source used to generate solar wind input information. Currently one of ACE-RT ACE-L2, WIND, OMNI, DSCOVR (real time)
 User-submitted data may be from any source or made-up. OMNI
despike_solar_wind_data 
Flag indicating whether to automatically de-spike solar wind (optional for automatically retrieved data only; use when solar wind data shown in next page have clusters of extreme values in plasma density, temperature or velocity).
 True
despike.threshold 
De-spike threshold (standard deviations)
 sigmas 2 4
despike.number_of_samples 
De-spike length (number of samples in cluster of extreme values to be eliminated)
 3 9
setting_option_for_Bx 
Indicates how solar wind Bx is set: Set Bx to a specified constant ('user') Set Bx to the initial solar wind data value ('init') Use average Bx from solar wind data ('auto')
 user
constant-Bx 
Constant Bx value fed into the front boundary of the simulation.
 nT 0
By-coefficient 
Coefficient for By in linear combination approximating Bx: Bx ~ constant-Bx + By-coefficient*By + Bz-coefficient*Bz
 0 -1 1
Bz-coefficient 
Coefficient for Bz in linear combination approximating Bx: Bx ~ constant-Bx + By-coefficient*By + Bz-coefficient*Bz
 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 -3.299 -100 100
By 
Dawn-dusk component of solar wind magnetic field.
 nT -14.29 -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 6.377 -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 -305.953 -3000 -200
Vy 
Plasma velocity in dawn-dusk direction.
 The orbital velocity of Earth (about 29 km/s) is usually neglected km/s 6.382 -500 500
Vz 
Solar wind plasma velocity in north-south direction.
 km/s 111.341 -500 500
N 
Solar wind plasma density.
 Mass density described in terms of number of protons per cubic centimeter. AMU/cm^3 7.27 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 61720 10000 2000000
sw_link 
Solar wind link
 plot
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
SW_density_floor_was_applied 
Flag indicating the solar wind density has been floored with SW_density_floor value to ensure that the model will run through the requested time interval.
 False
minimum_SW_Fast-Mode_mach_number 
Minimum solar wind Fast-Mode mach number
 1.23
SW_parameters_are_large 
Flag indicating whether solar wind velocity, density or dynamic pressure are large. If they are, the run is a special request requiring attention by CCMC staff. The variables will be accepted unless they exceed certain absolute maximum values.

Name of solar wind plot
