DGRF/IGRF Geomagnetic Field Model 1945 - 2025 (IGRF-13) and Related Parameters

This page enables the computation of International Geomagnetic Reference Field (IGRF) parameter profiles in altitude, (geographic) latitude, longitude, or year. The parameters include the magnetic field strength and vector components, the magnetic inclination and declination angles and the L value.
Note:this model does not include external sources!
* Select Year:
     Year(1945 - 2025):
* Select Coordinates
    Latitude(deg.,from -90. to 90.): Longitude(deg.,from 0. to 360.):
    Height (km, from 0. to 30000.):
* Select a Profile type and it parameters:
          Start Stop Stepsize
*Select output form:

Plot model data 
      Note 1: The first selected parameter below always will be along the X-axis, the other selections will be along Y-axis.
              (e.g. if you want a Height profile, you may specify Height as the first parameter in the listing below.)     
      Note 2: User may get scatter plot if he specifies any two parameters below and changes the "connect type"  
              in the "Advanced plot selections" to "show points only"   
* Select desired output parameters
