Atmospheric gravity wave induced airglow fluctuations of the hydroxyl OH Me
inel and other bands are: routinely observed using CCD imagers operating in
the near infrared wavelength region. Farther into the infrared, the intens
ity of the OH emissions is much greater. Recently, a new IR imaging camera
was modified for infrared viewing of the night sky with approximately 1 ste
radian field of view. The filter had a center wavelength of 1467 nm and a b
andwidth of 177 nm to include components of the OH (Delta v = 2) band. The
images show good signal-to-noise ratios of 180 with 10 second:exposures. Cr
oss-spectral and wavelet analysis:were used to obtain spatial and temporal
information about observed airglow fluctuations, and horizontal wavelengths
and wave periods as short as 3.7 km and 3 min, respectively, were determin
ed.
