Ionospheric tomography in Bayesian framework with Gaussian Markov random field priors

We are pleased to report that our latest study on ionospheric tomography with a GMRF-type prior information has been accepted for publication in Radio Science. The current reference is:

J. Norberg, L. Roininen, J. Vierinen, O. Amm, D. McKay-Bukowski and M. Lehtinen, Ionospheric tomography in Bayesian framework with Gaussian Markov random field priors, Radio Science, Accepted January 2015.

We will post a link to the early-access version as soon as it is available. This is a companion paper of the so-called "tomography receiver paper" reported in Radio Science earlier. It is available here.

Current tomography project titled 'TomoScand' is a collaboration project between Finnish Meteorological Institute, Sodankylä Geophysical Observatory and MIT Haystack Observatory.

Here is a schematic plot of ionospheric tomography, where the objective
is to probe the ionosphere beacon 150/400 MHz satellite signals and to estimate
the electron density ~60-1000 km above the Earth.
