Intensity variation of OH Meinel Bands in the Nightglow
By Jahangir Payamara
OH nightglow measurements from Firuzkuh mountain (52°34¢, 45°34¢) at height of 3000m( 30 km away from Tehran), were carried out for studying the mesosphere emission and its behavior, and the results obtained are reported. From OH (9,3) band , the intensities of entire OH Meinel band system (0.384m-4.47 m) has been evaluated. On the basis of ozone-hydrogen mechanism leading to the emission of OH Meinel bands in the nightglow, the estimated total OH band intensities are utilized to calculate ozone concentration prevailing at night time over Mt. Firuzkuh .
Key Words : Nightglow, Mesosphere, OH Meinel band
