Modeling impact of FORMOSAT-7/COSMIC-2 mission on ionospheric space weather monitoring
Listed in National Center for Atmospheric Research
For the past decade, the paucity of ionospheric observations has made it almost impossible to reconstruct the three-dimensional structures of global ionospheric electron density.
Description
The Formosa Satellite-3/Constellation Observing System for Meteorology, Ionosphere and Climate (FORMOSAT-3/COSMIC, F3/C) constellation has provided ionospheric electron density profiles with high vertical resolution through radio occultation measurements.
Slated for deployment starting in 2016, the FORMOSAT-7/COSMIC-2 (F7/C2) constellation will further provide more than 4 times the number of the F3/C occultation soundings. An observing system simulation experiment is conducted to determine the impact of F7/C2 on ionospheric weather monitoring. The results first show that the F7/C2 observations can reconstruct 3-D ionospheric structure with a data accumulation period of 1âh, which can advance studies of small spatial/temporal scale variation/signatures in the ionosphere.

Comparing to assimilation results of F3/C, the assimilation system significantly reduces the error arising in the models and observations after assimilating synthetic observations of F7/C2. During this observing system simulation experiment period, the averaged root-mean-square error percentage for the results of F7/C2 is about 4.4%, lower than that of F3/C 7.3%. Furthermore, even with an assimilation window of less than 60âmin, the F7/C2 RMS errors still yield reliable values compared to the F3/C results.
This paper represents a major advance in ionospheric weather monitoring for the future mission.
