The authors speak about 100 ppb of NO observed by HALOE in the mesosphere only in January 2004 at mid-latitudes, and state that ‘‘there was sufficient mesospheric NO available

This contribution describes the first step into this direction: The nocturnal transionospheric attenuation of 100 kHz radio waves from LORAN transmissions is determined by

A kinetic model of electron energy deposition is used to determine optical emissions and electron heating, and a fluid approach is used to capture the ionospheric upflow

[ 26 ] Figures 8 and 9 suggest that there is a connection between the frequency deviation of individual lines forming the PLHR events from the exact harmonic multiples of power

In the entire data set, we have found only 58 cases of PLHR-like events which can be divided into three classes: (1) 10 events where the frequency separation of spectral lines is

six FREJA time-frequency points, computed using the following three methods (from top to bottom): the entropy regularization algorithm (ERA), the Gaussian peaks method (GP), and

It is shown that there are two principally different classes of events: (1) events with frequency spacing of 50/100 or 60/120 Hz (power line harmonic radiation, PLHR) and (2)

How- ever, global seismic characterization of this layer, in combination with mineral physics results, suggest that such a Br-pPv transition in a pyrolitic mantle cannot reconcile
