Abstract
An empirical electron density model, quick-run ionospheric electron (NeQuick), has been
selected for the modelling of the ionospheric electron density pro le. NeQuick iono-
spheric electron density model produces the full electron density pro le in the ionosphere.
The electron density pro les (EDP) from NeQuick model before and after ingestion of
the ionosonde key parameters (foE, hmE, foF2 and hmF2) have been compared with
ionosonde electron density pro le for bottom side ionosphere from HF-viper radar in-
stalled at Welmera site. The comparisions show that the NeQuick model after ingestion
of key parameters from ionosonde generally agrees well with the ionosonde observation.
The root mean square deviation (RMSD) and correlation coe cient (R) for the two data
sets are computed for the selected time. The RMSD of the NeQuick model after ingestion
of ionosonde key parameters are lower than those values before ingestion of ionosonde
key parameters. The computed correlation coe cients (R) also show an existence of
stronger relationship after ingesting ionosonde key parameter values than those values
before ingesting ionosonde key parameter values
