On December 7, 2001, SABER, a cooled multichannel radiometer, was launched aboard the TIMED satellite. In January of 2002
the SABER instrument began returning airglow limb scan measurements from around the globe. Data now available include 65%
of 2002, 75% of 2003, and 40% of 2004. Experimental data were taken from SABER for two radiometric channels centered at
$\lambda$=1.6 $\mu$m and 2.06 $\mu$m. Volume emission rates (VER) were computed at the peaks of the OH layer profiles and
then the magnitudes were displayed as a function of the latitude and longitude of the tangent point of the observation. The
Mlynczak unfiltering algorithm for OH emissions was used to obtain absolute values for the maximum VER of the total sequence
of OH vibration-rotation band emissions. The maximum VER was found to be greater near the equator compared with high
latitudes. In addition, seasonal effects on the global distribution of the nighttime OH airglow were explored for the
available data in 2002, 2003, and part of 2004. Algorithmic methods of optimized geographic visualization for this
unprecedented wealth of mesospheric airglow data were also explored.
