IC-WG1.2: Modelling environmental loading effects for Reference Frame realizations




The principle objectives of the scientific work are to investigate if loading corrections are necessary for TRF adjustment and if necessary, investigate the optimal methods to deal with loading effe

  • Determine how best to apply loading corrections: observation level or daily averages?

  • If corrections are applied at the observation level, how can the displacement signal be reapplied to the station displacement time series?

  • Address whether all geodetic techniques see the same level of loading contributions. In particular, some studies have shown that GPS seems to have larger annual and semi-annual signals than other geodetic methods and calculations from geophysical fluid loading.
