Correlation Between Mapping Functions and Atmospheric Pressure Loading in the Processing of GNSS Data
Abstract
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.
