On the difference between real-time and research simulations with CTIPe

Understanding the thermosphere and ionosphere conditions is crucial for spacecraft operations and many applications using radio signal transmission (e.g. in communication and navigation). In this sense, physics based modelling plays an important role, since it can adequately reproduce the complex coupling mechanisms in the magnetosphere-ionosphere-thermosphere (MIT) system. The accuracy of the physics based model results does not only depend on the appropriate implementation of the physical processes, but also on the quality of the input data (forcing). In this study, we analyze the impact of input data uncertainties on the model results. We use the Coupled Thermosphere Ionosphere Plasmasphere electrodynamics model (CTIPe), which requires satellite based solar wind, interplanetary field and hemispheric power data from ACE and TIROS/NOAA missions. To identify the impact of the forcing uncertainties, two model runs are compared against each other. The first run uses the input data that were available in real-time (operational) and the second run uses the best estimate obtained in post-processing (research or historical run).

Ionosphere VHF scintillations over Vaddeswaram (Geographic Latitude 16.31° N, Geographic Longitude 80.30° E, Dip 18° N), a latitude Indian station--A case study

This research reports the 250\ MHz amplitude ionosphere scintillations recorded at Vaddeswaram (Geographic Latitude 16.31\textdegreeN, Geographic Longitude 80.30\textdegreeE, Dip 18\textdegreeN), a low-latitude station in India. Though amplitude scintillations were recorded for four continuous days (05\textendash08 November 2011), the presence of intense and long-duration scintillations on 06 November 2011 instigated us to verify the ionosphere background conditions. This research, therefore, is also used important databases including, diurnal variations of h F (virtual height of the F-layer) and the vertical drifts as measured by an advanced digital ionosonde radar located at an Indian equatorial station i.e. Trivandrum (Geographic Latitude 8.5\textdegreeN, Geographic Longitude 77\textdegreeE, Dip 0.5\textdegreeN), equatorial Electrojet (EEJ) ground strength measured using magnetometers and the total electron content (TEC) maps provided by the International GPS Service (IGS) to study the background ionosphere conditions. The interesting observations are higher E\ \texttimes\ B drifts, the occurrence of long-duration range-type spread F signatures at Trivandrum and, thereafter, intense scintillations over Vaddeswaram. It was found a secondary peak at around 1600 LT in EEJ strength followed by a higher upward drift velocity (more than 60\ m/s) with a significant raise of the F region up to 470\ km over the magnetic equator on 06 November 2011. The possible physical mechanisms of these important observational results are discussed in the light of available literature.

Testing regional vertical total electron content maps over Europe during the 17—21 January 2005 sudden space weather event

The intense level of solar activity recorded from 16 to 23 January 2005 led to a series of events with different signatures at the Earth s ionospheric distances. Measurements of the critical frequency of the F 2 layer f o F 2 and the vertical total electron content (VTEC) are used to describe the temporal and spatial electron density distributions during this space weather event, which gives an excellent opportunity to test regional VTEC maps over Europe under such disturbed solar-terrestrial conditions. In this context, the tests used to validate the International GNSS Service (IGS) VTEC maps have been applied to assess the accuracy of the European Rutherford Appleton Laboratory (RAL) VTEC maps.
