Today the ASTRON daily image featured a very interesting image in terms of geophysics. It featured a total electron content measurement produced by listening to a strong radio source using four different stations. This is interesting because if one can produce such measurements using many different radio sources, it would be possible to use this for three dimensional ionospheric tomography.
