New investigation on the choice of the tailored geopotential model for Algeria

The study shows that the newly released combined model (EIGEN-GL04C) is consistently superior to other models in the Algerian region. Its standard deviation fit with GPS/levelling data is 30 cm and 27.5 cm before and after fitting. Hence, we strongly recommend the use of this new model in the computation of the new gravimetric geoid model for Algeria.
