Abstract: Ionosphere is a part of the atmosphere which is formed due to solar ultraviolet radiation on the atmosphere. It continues from high altitudes to near the Earth's surface. It is divided into different layers such as D, E, and F and… due to the ionization rate and the density of electron, ions and some other factors. Ionosphere is known as an environmental plasma conditions. One of the interesting phenomena in the Ionosphere is the plasma occurrence of ES. This phenomenon is occasional and it may disappear in short time range. We are searching for the correlation between two phenomena as Es-plasma layer height and the earth geomagnetism activities. To do this, we study the correlation of these two parameters at the four main moon phases. When the moon is experiencing one of its main phases, the tide goes in and out to its maximum or minimum values. As the gravitational forces cause tide to occur through affecting the surface tension of the sea waters, they take the same effect on the Ionosphere and the E-layer and cause the lunar tidal effects in this layer. Our investigations in the Ionosphere Station at Boulder, Colorado which located in the mid-latitude-that have been done in periods categorized by the mid-day tides, revealed that in each period, the variations of the correlation coefficient between Es-plasma layer height occurrence and the earth geomagnetism activities are the same for each main phases of moon in different months.
