Kp 
Geomagnetic Activity index. If KP is specified and POWER and/or CTPOTEN are commented, then the given KP will be used with empirical formulas to calculate POWER and/or CTPOTEN, which are used in the Auroral parameterization.

KP can be provided as a scalar constant (KP), or as a series of time-dependent values (KP_TIME), as in the below examples. KP cannot be set if GPI_NCFILE data file is specified.

Empirical formula used to calculate POWER from KP (see function hp_from_kp in util.F):

if (kp <=7.) hp_from_kp = 16.82*exp(0.32*kp)-4.86
if (kp > 7.) hp_from_kp = 153.13 + (kp-7.)/(9.-7.)*(300.-153.13)
Empirical formula used to calculate CTPOTEN from KP (see function ctpoten_from_kp in util.F):

ctpoten_from_kp = 15.+15.*kp + 0.8*kp**2

Examples:
KP = 4.0
KP_TIME = 80,0,0,4., 80,6,0,4.5, 80,12,0,5.0

SWden 
Solar Wind Density (#/cm-3). Can be specified as either a constant (SWDEN), or series of time-dependent values (SWDEN_TIME). If IMF_NCFILE is set and SWDEN is not provided, then it SWDEN will be taken from the IMF data file.

Data type: real or real array

Examples:
SWDEN = 4.0 ; constant for entire run
SWDEN_TIME = 80,0,0,2., 80,1,0,3., 80,2,0,4. ; time series
#/cm-3
SWvel 
Solar Wind Velocity (Km/s). Can be specified as either a constant (SWVEL), or series of time-dependent values (SWVEL_TIME). If IMF_NCFILE is set and SWVEL is not provided, then it SWVEL will be taken from the IMF data file.

Data type: real or real array

Examples:
SWVEL = 400. ; constant for entire run
SWVEL_TIME = 80,0,0,100., 80,1,0,200., 80,2,0,300. ; time series
 Km/s
ztop 
Upper model boundary height. Examples: ZTOP =7, the model upper boundary is around 500 km at solar max. ZTOP = 11, the upper boundary is around 1000 km at solar max.

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.
Name Description Caveats Units Default Value or Actual Value Valid Min Valid Max
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 -100 100
By 
Dawn-dusk component of solar wind magnetic field.
 nT -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.
