Abstract

Recent developments and the integration of an InGaAs detector with a precision, compact Michelson interferometer have provided a very sensitive, reliable, and portable measurement tool for studying near infrared upper atmospheric emissions. Spectrically resolved and calibrated line intensity measurements of major portions of the Δν = 2 and the Δν = 3 band sequences of the OH Meinel airglow emissions are obtainable from ground based sites. Typically, the spectrometer provides signal-to-noise ratios of 50/1 in one minute measurement time. Time resolved rotational OH temperatures and therefore ambient temperatures corresponding to the 80 to 95 Km OH emission region can be obtained from the data. Also the metastable excited state (alAg) of the molecular 02 (0,0) band at 1.27 pm and the (0,1) band at 1.58 pm are measurable. It is even possible to observe the OH and 02 emissions during the twilight corresponding to sun illuminated conditions at the emission altitudes if spectral discrimination and background suppression techniques are applied to reduce the unwanted effects of scattered solar radiation. Thus, continuous measurements of the emissions can be performed during the daytime to nighttime transition and throughout the night.
