Abstract

Characteristics of spectrographs intended for measurement of radiation intensity of the OH (3-1) band and determination of the atmosphere temperature at a glow height by its rotational structure are presented. The Shamrock 303i spectrographs supplied by high-sensitive infrared InGaAs photodiode register of Andor Technolog company have been installed at the Maimaga (63 ° N, 129.5 ° E) and Tixie (71.5 ° N, 129 ° E) stations. The technique of measurement of the rotational temperature, estimation of casual and regular errors is described. The calibration measurements with two spectrographs at Majmaga station have shown that the difference of nightly average values of temperature does not exceed errors of measurement with the device.
