Analysis shows that the terrain environment and instrument installa- tion height on the ground have a great influence on the ground atmospheric electric field mea- surement results, which makes the atmospheric electric field instrument data lack of comparabil- ity between each observation point. It is concluded that the installation of the electric field in- strument must consider environmental factors, it away from the obstacle distance shall not be less than 3 times of the barrier height and 2 times of the width, considering the influence of the barrier height c and width depth ratio a/b at the same time. The influence of the height and environmental equipment can use linear fitting to correct with reference to the standard measurement data. Keywords Atmospheric Electric Fiel
