Vertical and Oblique Ionosphere Sounding During the 21 August 2017 Solar Eclipse
Geophysical Research Letters, 2018 On 21 August 2017, a total solar eclipse crossed North America. Two Vertical Incident Pulsed Ionospheric Radar ionosondes were operated, one deployed under totality at Lusk, Wyoming, and another south of totality, 313 km away from the geomagnetic ...

Bayesian statistical ionospheric tomography improved by incorporating ionosonde measurements [PDF]
Atmospheric Measurement Techniques, 2016 We validate two-dimensional ionospheric tomography reconstructions against EISCAT incoherent scatter radar measurements. Our tomography method is based on Bayesian statistical inversion with prior distribution given by its mean and covariance. We employ
