Abstract: Ionosphere is a part of the atmosphere which is formed due to solar ultraviolet radiation on the atmosphere. It stretched from high altitudes heights above the earth surface to near the Earth's. It is divided into different layers such as D, E, and F and… due to the ionization rate and the density of electrons and ions and some other factors. Ionosphere is knownas an environmental plasma medium. The lunar tide has always been regarded interesting as one of the notable phenomenon in the ionosphere, and significant due to fact that is indicates a close correlation between ionosphere and specifications of the layered shape of the plasma movements .In this study the lunar tide in the E layer of the ionosphere in the mid-latitude, has been determined by the analysis of the foE and hmE parameters in 2009 year, while the selected site is Boulder Colorado.When the moon is experiencing one of its four main phases, the tide goes to its maximum or minimum values. So we study correlation of the height (hmE) and critical frequency (foE) in these days. The investigations revealed that, the correlation coefficient between the hmE and foE varies with the variation of the moon phase, but these variations are the same for each of the moon main phases in different months.
