Swarm Update 2/21/22

This is the Earth’s magnetic field strength for March 2019 by day, taken from the Swarm satellite array. The image is the Earth’s surface broken into “equal-area” parts. Equal areas allow us to calculate a general average field strength despite the Swarm satellites spending vastly more time at the poles.

We determined the bad frames came from improper null handling, which we already fixed in the code.

I’m seeing a slight uptrend for the global mean strength for the Earth’s magnetic field during March 2019, but it’s not significant. 34090 to 34130 is only a 0.11% difference.

Now I’m off to process some more data…
