| Abstract | In this study, an investigation of data ingestion into the NeQuick 2 model using networks of ground-based Global Navigation Satellite (GNSS) has been carried out for different spatial resolutions over South America. This serves as a benchmark for cost-effectiveness in using ground-based GNSS observation for the update and validation of NeQuick 2 for a near-real-time specification of the state of the ionosphere. Statistical analysis based on spatial index selection of GNSS data shows an improvement in both middle and lowlatitude regions considering ingestion of data over the regions separately. We observed a decrease in the RMSE between the NeQuick 2 and GNSS observation as the number of ingested GNSS TEC data increases over the test stations with an average improvement of about 26 % and 28 % for both 34 and 120 observations. Our results showed that the datadriven NeQuick 2 model is able to describe the evolution of the Equatorial Ionization Anomaly during both quiet (10 March 2015) and disturbed (17 March 2015) geomagnetic conditions. The diurnal variation of vTEC, hmF2, and Ne over the test stations showed considerable improvement after data ingestion. Validation with Ionosonde measurements and COSMIC Radio Occultation data showed significant improvement in reconstructing the electron density of the bottomside and topside ionosphere profiles after data ingestion. Between the altitude of 100-250 km, the NeQuick $%&2 is in good agreement with ionosonde measurement with an average correlation coefficient of 0.95 and 0.83 at Sao Luis (2.58°S, 44.20°S), 0.94 and 0.91 at Boavista (2.83°N, 60.70°S), and 0.75 and 0.71 at Campo Grande (20.40°S, 54.50°S) during quiet and disturbed conditions. Likewise, the biases obtained for the peak electron density ($%&2 ) at different times are larger compared to those estimated for the peak height (ℎm&2). | |||
