AB: Near-global retrievals of mesopause OH rotational temperatures from satellite-borne Meinel band emission measurements are presented. The nighttime measurements of the OH (3-1) Meinel band near 1.5 micron were performed with the SCIAMACHY instrument on the European Space Agency's environmental satellite Envisat. The derived OH (3-1) rotational temperatures were previously shown to be in reasonable agreement with the CIRA-86 atmosphere temperatures for the seasons and latitudes considered and in good agreement with ground-based OH rotational temperature measurements at different locations. This contribution presents results of the first 2 years of OH temperature data derived from SCIAMACHY. The SCIAMACHY limb nighttime observations provide a unique data set of near-global OH rotational temperature to study seasonal and geographical variations, dynamical processes and possibly long-term temperature trends, if an extended data set becomes available in the future.
