This work focuses on some currently used high‐degree geopotential models that represent the gravity field in Spain. Six test areas of different topographic structures that cover the greatest part of the territory are selected to get information on the gravity field. A number of 27,691 free‐air gravity anomalies and three geopotential models are considered in this work. Comparisons of free‐air and geopotential models‐implied anomalies are studied in the test areas and in all of Spain. The results show that the model IFE88E2 is the most suitable for use as a reference field in the region of Spain.
