AB: Automatic weather stations equipped with GPS (AWS/GPS) have recently been deployed on giant tabular icebergs in the Ross Sea. The aim of the project is to use the {\em{in situ}} data to formulate an accurate dynamical iceberg drift model for the Southern Ocean. A prerequisite for future dynamical drift models is a systematic evaluation of the data's integrity and its relationship to existing data sources. To this end a statistical analysis of the last 2 years is performed on the meteorological data from iceberg AWS/GPS stations and surrounding Antarctic stations. The results of this analysis are presented as a guide for future drift models.
