Where Can I Find Earth's Magnetic Field Values for Major Cities?

[noospace]

Hi all,

Does anyone know where I could find values for the Earth's magnetic field at major cities?

Thanks

I googled Earth's magnetic field map cities, and the 3rd hit is from the USGS. Looks pretty promising:

for your question! The Earth's magnetic field can vary in strength and direction at different locations on the planet, so there are no fixed values for major cities. However, you can find real-time measurements of the Earth's magnetic field at various locations around the world on the National Oceanic and Atmospheric Administration (NOAA) website. These measurements are constantly updated and can give you an idea of the current strength and direction of the Earth's magnetic field at different locations. Additionally, there are also historical data available from various scientific organizations that can provide information on past measurements of the Earth's magnetic field at specific cities. I recommend checking with the International Association of Geomagnetism and Aeronomy for more information on accessing this data.
