AbstractWe present rotational temperature measurements of the mesospheric OH emission layer using a meridional imaging spectrograph at Millstone Hill (42.6°N, 72.5°W). The system is equipped with a state-of-the-art bare-CCD detector and can yield simultaneous quasi-meridional images of the mesospheric OH and O2 intensity and temperature fields at 87 and 94km altitude during the course of each night. A cross-validation study of the rotational OH temperature measurements obtained on 61 nights during the autumnal months of 2005–2007 was undertaken with near-simultaneous kinetic temperature measurements made by the SABER instrument aboard the NASA TIMED satellite during overpasses of Millstone Hill. Excellent agreement was obtained between the two datasets with the small differences being attributable to differences in the spatial and temporal averaging inherent between the two datasets.
