Resumen:
During the
last decade the amount of ionosphere measurements, from ground and space born
sources, has substantially increased along with the development of high end
processing systems. This constitutes a perfect scenario for the International Reference
Ionosphere (IRI) to assimilate this huge new database and to satisfy the new
needs of the aeronomic community: an IRI with meteorological capability.
The first step
before the implementation of an assimilative procedure is to validate the new
data. This work intends to contribute in this direction by studying the
differences (systematic and statistical) between the F2 peak parameters (hmF2
and NmF2) predicted by the IRI(CCIR) and those obtained from the electron
density profiles computed with LPIM-COSMIC/Formosat3 (LPIM-C/F3) technique. The
analyzed period extends from January 2007 to October 2012, thus covering all
the different seasonal Sun-Earth configurations and a range of solar activity
going from low to mid-high level.
The analysis shows that there is no significant
systematic bias between the IRI and LPIM-C/F3 values on both parameters. The obtained
differences are comparable to those found between IRI and other models and data
sources. In addition a correlation with the solar activity level is observed. The
analysis performed is also helpful to study and asses the potentiality of the meteorological information contained in the LPIM-C/F3
by analyzing the standard deviation of the differences. This extra information could
represent the key element to improve the IRI predicting capabilities.
