Real-time Internal (Ist) and External (Est) Storm Time Indices
One-minute real-time disturbance storm time index (Dst) is driven by the real-time Dst index provided by the USGS magnetic observatory network. Dst is separated into internal storm time index (Ist) and external storm time index (Est).

 
 
World Magnetic Model 2015 Google spreadsheet Application
Google spreadsheet calculator based on the World Magnetic Model

 

Operational Calculators:

These calculators are hosted at NOAA's National Centers for Environmental Information (NCEI).

 
 
Declination
Online magnetic declination calculator based on the International Geomagnetic Reference Field and the World Magnetic Model.

 
 
Field Value Calculator
Online magnetic field value calculator based on the International Geomagnetic Reference Field Model and the World Magnetic Model.

 
 
Grid Magnetic Field Calculator
Online magnetic field value grid calculator based on the International Geomagnetic Reference Field Model and the World Magnetic Model.

 
US Historic Calculator
Online historical (1750-2010) magnetic declination calculator based on the IGRF and USD polynomial models.

 

Backup Calculators:

They may be used as back-up calculators to the geomagnetism calculators. The IGRF+ calculates field values back to 1590 using the gUFM. These calculators include the google maps API.
