SPAPT

Function

Calculates the T01 magnetic field model on a given grid.

Syntax


GMSField = t01(Inputfile, MHDTime, LFMGrid, Linenumber);

Inputs
Name Type Default Description
Inputfile string none input file
MHDTime vector none input MHD time field
LFMGrid field none LFM grid points
Linenumber integer none linenumber from a loop

Outputs
Name Type Description
GSMField field GSM magnetic field 3 vector
Lastlinenumber integer that matches MHDTime

Functional Details

This module reads in a 'T01.input' file for all valid MHD times in a run.
It takes a MHD time and interpolates through the input field to find the correct inputs.
The T01 model field is calculated from sources of the geomagnetic field at specific points in space.

Inputfile

contains 10 columns of the following data
yyyy 4 digit year
doy day of year
hh.hhhh decimal hour
swp solar wind pressure [nP]
Dst [nT]
By [nT]
Bz [nT]
DipAngle earth's dipole tilt angle [radian]
G1 Tsyganenko IMF-related index
G2 Tsyganenko IMF-related index

MHDTime

gets the input from

LFMGrid

contains the grid points on which the T01 field is computed.
The points cannot lie beyond of 15 earth radii on the tailward side.

Linenummber

is the last line number of the input file that matched the MHD time.
