Preliminary results of a comparison of the rotational temperature of the hydroxyl at the height mesopause measured at two different latitudes

摘要

The report presents a comparison of the rotational temperatures of OH band (3, 1) at an altitude of about 87 km measured by two spectrographs installed at the optical stations: Maimaga (63.04 ° N, 129.51 ° E), which is located 120 kilometers north of Yakutsk and Tiksi (71.6 ° N, 128.7 ° E).
