Abstract

In the field of ionospheric research is impossible to obtain the new results, new knowledge without use of Internet resources. The paper provides examples of the use of these resources on the basis of generalization and complement to reports made on the three previous ICTRS conferences. Results are presented in four areas of possible data: (1) vertical sounding, (2) total electron content ТЕС, measured by high orbit navigation satellites, (3) plasma frequencies measured by low orbit satellites, (4) empirical models of the ionosphere. The main achievement in the first direction is the creation of GAMBIT, designed to provide global maps of ionospheric parameters foF2 and hmF2 with delay of 15 minutes in relation to real time. The estimation of conformity of the IRI model to experimental data of foF2 for high-latitude station of southern hemisphere is made. Within the second direction the effectiveness coefficient of use of the observational median of the equivalent slab thickness in comparison with thickness of the IRI model is introduced. It is shown that this coefficient almost always exceeds 1, reaching values 1.5-2 globally. Behavior features of deviations of calculated foF2 from observational values during the strongest geomagnetic disturbances of April 2014 and March 2015 are given. In the framework of the third direction validation of a plasmaspheric part of a N(h)-profile according to satellite IMAGE data is performed. It was concluded that to disambiguate N(h)-profiles it is necessary to improve both values of ТЕС, and the shape of the topside part because the plasmaspheric part is close to existing model RPI. Within the fourth direction the statistics of comparisons of various models was increased including high-latitude region of the southern hemisphere.
