Validation Of Nequick Model Using Ionosonde Over East Africa Longitude Sector

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