AB: The TIMED Doppler Interferometer (TIDI) has been measuring winds in the mesosphere and lower thermosphere since the beginning of 2002. From the beginning of the TIMED mission until March 2005, the High Resolution Doppler Imager (HRDI) on the Upper Atmosphere Satellite (UARS) also measured winds in the same region. It is very desirable to compare the wind field from the two instruments. This three year overlap permits a comprehensive validation of the winds and more importantly allows scientific studies that are difficult or impossible with a single data set. For example, tidal analysis with one instrument requires assumptions about structure of the tide for analysis to proceed. Difficulties in removing instrument artifacts in the TIDI data and correcting for a loss of precision attitude knowledge on the UARS spacecraft have so far prevented these studies. These problems are now largely resolved. This paper will compare the two data sets during the time of mutual operation. The data coverage and accuracies will be discussed as well as the times when the data is best used for validation and when for two instrument scientific studies.
