Atmospheric delay for electromagnetic signals associated with space / time variations of the refractive index in the lower atmosphere: Applications in spatial geodesy

The feasibility quantifying atmospheric delay of electromagnetic signals using a mesoscale numerical model (WRF model) is explored. The experiment investigates a new alternative to reduce uncertainty sources in data exploitation for spatial geodesy applications. Our experiment was compared with GPS estimations of stations located in the South-America. The GPS estimations are consistent with values of our proposed methodology. This opens the possibility of using a mesoscale numerical model applied to spatial geodesy. However, these results, despite being promising, need further analysis and research, opening the opportunity to numerical modeling of atmospheric delays using mesoscale models
