Calculation the Earth Gravity Najaf and Kufa city / Iraq with New Model


In this research paper, The Earth gravity between Najaf and Kufa city/ Iraq (latitude 32.5 – 33.50), has been studies, and the Earth gravity for altitude (30-60 m) for Troposphere layer (60-1030m) above sea level has been calculated. The results explained that the Earth gravity in this region was less than that in sea level, A new model for Earth gravity with altitude has been found; and it was very compatible with the word research.
