AB: We investigate the correlation between mapping functions and atmospheric pressure loading in the processing of GNSS data. Previous work from the same authors showed that site dependent mapping functions (especially a total mapping function) based on the ray tracing of a numerical weather model give coordinate and ZTD times series that, when differentiated with time series obtained with a traditional mapping function like the NMF, show high level of correlation with the predicted atmosphere pressure loading signal.
