There exists presently a total of about 20 Fabry-Perot interferometer (FPI) observatories at various national and international locations around the globe dispersed between the polar and equatorial regions. These instruments operate on the principle of measuring the Doppler shifts and Doppler widths of atmospheric spectral lines emitted by metastable atomic species that are sufficiently long-lived in the mesosphere and thermosphere regions for local equilibrium to be attained before emission. Possible sources of these emissions are the layers of nightglow and dayglow emissions which originate from the production of active species as a consequence of the ionospheric chemistry of the upper atmosphere. At high latitudes the aurora generated by precipitating electrons or protons also represents a significant emission source. The determination of zonal and vertical wind components by these FPI observatories represents unique information concerning the dynamics of the upper atmosphere for both regions not available from other instrumental sources utilizing passive remote sensing principles. If these data products of temperature and winds for both regions could be assimilated within a reasonable elapse of time (perhaps one hour), these results would provide valuable constraints upon the bounds of modeling real-time parameters for thermospheric and mesospheric dynamics. The application of information technology can be readily envisioned to achieve the analysis of FPI data required for real time display and through transfer over the Internet network for data assimilation into global modeling codes. This paper would summarize the problems and science yields in achieving the assimilation of such measurements into the modeling framework envisioned.
