Geomagnetic Field Calculators
info
Use the tool below to compute the model magnetic field for a given set of the GSW coordinates and date. There are two options: upload a file containing your input data or enter them in the form.
This feature is under development, in case of any problems or questions please contact Dr. Andreeva.
caution
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. The calculator works only for the years between 1995 and 2020 (both included) due to the availability of OMNI data.
- Upload the input file
- Fill in the form
Upload the input file (suitable for a large data set)
- Select a model (to the present moment, the TS05, the TA15, and the RBF-based TA16 models are available).
- Compile an input file containing 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. There are two options for the input:
- To calculate the total (external+internal) field, put
iflag=1
in the input file. Otherwise (iflag=0), 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 the button Submit request. While waiting you can reload the page Then the calculation is done, you will be able to download the results in file
output.dat
oroutput.csv
, in the same format as your input data, but with additional three columns containing model Bx, By, and Bz in the GSW system.
Fill in the form (better for a few points)
- Select a model (to the present moment, the TS05, the TA15, and the RBF-based TA16 models are available).
- 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.
- 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 on the button Submit request. To add another point, click on the button + Add point, enter the data, and click Submit.
