Although atomic oxygen density, [O], is a key state parameter of the upper atmosphere, its empirical estimation is notoriously difficult. At mid-latitudes, OI 844.6 nm emission brightness is a potentially excellent proxy for [O], and recent improvements to its forward emission model warrant renewed effort to pursue ground-based sensing using this unique emission. This proposal represents a first step toward the development of this long-overdue capability. The scientific goals are two-fold: (1) to reduce the uncertainty in a key parameter ­ neutral meridional wind speed ­ of the forward model of 844.6 nm emission generation and (2) to assess the conditions for which the existing forward model is justified in its neglect of a key alternative source of 844.6 nm production ­ radiative recombination of O+. To this end, we propose several observational campaigns, spanning a variety of seasonal conditions, using combined passive optical and incoherent scatter radar instrumentation.
