From September 01 to October 31, 2009, the first global NDMC measurement campaign has been conducted. Several of the globally distributed NDMC stations provided rotational temperature data derived from ground-based measurements of the OH and O2 emissions, which have their origin in the mesopause region (80-100km). This campaign dataset provides an excellent opportunity for intercomparison between the contributing stations whereby satellite observations from instruments such as SABER on TIMED or SCIAMACHY on ENVISAT are used as a "transfer standard" between the ground based observations. Data for the intercomparison are chosen following equal miss time and miss distance criteria for every instrument location. Airglow-equivalent temperatures are derived from the satellite temperature profiles by applying an appropriate weighting function. The differences at each location between satellite and ground based temperatures and a preliminary overall uncertainty based on the available data for the ground-based network is presented.
