Model Output File Format Description

Model output files should be in ASCII text format. Each file size should not exceed 1Mb. Full path name to the input file at your local disk should not contain any blank spaces or quotation marks. On DOS/Windows systems the recommended extension for the input file name is "txt".

The following file formats for model outputs for different physical parameters studies are expected:

Magnetic field at geosynchronous orbit

Year Month Day Hour Min Sec XGSE[Re] YGSE[Re] ZGSE[Re] BXGSE[nT] BYGSE[nT] BZGSE[nT]

Here BXGSE[nT] BYGSE[nT] BZGSE[nT] are magnetic field components at GOES position (XGSE[Re] YGSE[Re] ZGSE[Re] ) in GSE coordinates.

Ground magnetic perturbations

Year Month Day Hour Min Sec GeomagLat [deg] GeomagLon[deg] B_NorthGeomag[nT], B_EastGeomag[nT], B_DownGeomag[nT]

Here B_NorthGeomag[nT], B_EastGeomag[nT], B_DownGeomag[nT] are components of magnetic field perturbation (north, east, down) at ground station location (Geomagnetic Latitude, Geomagnetic Longitude). Please note that Geomagnetic Dipole Coordinates (Hapgood, 1992) are used.
