Use the tool below to compute the model magnetic field for a given set of the GSW coordinates and date. This calculator uses the empirical magnetic field models available on this webpage (to download the Fortran source codes please see the 'Magnetic field' panel in the sidebar on the left).
This feature is under development, in case of any problems or questions please contact Dr. Andreeva.
How to use:
Enter the date, the universal time (UT), and the X, Y, Z GSW coordinates. The radius of the Earth is used as the unit of measure for distance, km. The calculator works only for the years between 1995 and 2020 (both included) due to the availablity of OMNI data.
To calculate the total (external+internal) field, mark the checkbox 'Total field'. Otherwise, only the external field will be calculated. Here we use the IGRF-13 magnetic field model for the internal field.
To obtain the result, click to the button 'Submit'. To add another point, click to the button '+Add point', enter the data, and click 'Submit'.
ATTENTION: If all , , components are equal to 0, the point is outside of the model magnetopause. If all three components are equal to -99, there is no input OMNI data available for this date.
