Retrieval of thermospheric parameters from routine ionospheric observations: assessment of method\textquoterights performance at mid-latitudes daytime hours

A new method has been developed to retrieve neutral temperature T_n and composition [O], [N₂], [O₂] from electron density profiles in the daytime mid-latitude F₂-region under both quiet and disturbed conditions. A comparison with CHAMP neutral gas density observations in the vicinity of Millstone Hill Incoherent Scatter Radar (ISR) has shown that the retrieved neutral gas densities coincide with the observed ones within the announced accuracy of CHAMP observations, provided that accurate N_e(h) ISR profiles are used for the retrieval. The performance of the method has also been tested ingesting Digisonde N_e(h) profiles. In this case the agreement with CHAMP neutral gas density observations is less successful. Possible factors that can influence the performance accuracy are investigated. These are mostly related to limitations due to the ionogram scaling and inversion methods, including performance limitations of the sounding technique itself, like for instance during G-conditions. Several tests presented here demonstrate that discrepancies in the hmF2 values provided by the Digisondes could have an important impact on the performance of the method. It should be noted that in all tests performed here using Digisonde N_e(h) profiles, the topside part is approximated with the NeQuick model and any assessment concerning the impact of the topside profiler on the accuracy of the method is beyond the scope of this investigation. Despite the limitations related to the use of Digisonde profiles, the proposed method has the potential to monitor the thermosphere at least with ISR N_e(h) profiles. Digisonde electron density profiles can also be used if quality improvements are made concerning the ionogram inversion methods.

Near Earth space plasma monitoring under COST 296

This review paper presents the main achievements of the near Earth space plasma monitoring under COST 296

Action. The outputs of the COST 296 community making data, historical and real-time, standardized and available\ to the ionospheric community for their research, applications and modeling purposes are presented. The contribution\ of COST 296 with the added value of the validated data made possible a trusted ionospheric monitoring\ for research and modeling purposes, and it served for testing and improving the algorithms producing real-time

data and providing data users measurement uncertainties. These value added data also served for calibration and

validation of space-borne sensors. New techniques and parameters have been developed for monitoring the near\ Earth space plasma, as time dependent 2D maps of vertical total electron content (vTEC), other key ionospheric\ parameters and activity indices for distinguishing disturbed ionospheric conditions, as well as a technique for improving\ the discrepancies of different mapping services. The dissemination of the above products has been developed\ by COST 296 participants throughout the websites making them available on-line for real-time applications.
