      abstract     = {We use theory and global ray modeling to investigate how
                      the potential of gravity waves to transport momentum flux
                      globally from the lower atmosphere into the mesosphere and
                      lower thermosphere (MLT) varies with horizontal wavelength
                      and ground-based phase speed. Ray modeling is performed
                      using the Gravity Wave Regional or Global Ray Tracer
                      (GROGRAT) interfaced to realistic three-dimensional global
                      winds and temperatures from 0 to 100 km altitude, specified
                      by fusing analysis fields at lower altitudes to GCM results
                      higher up. We focus on gravity waves in the short 10- to
                      50-km horizontal wavelength range that are unresolved by
                      global models and, according to theory, can transport
                      appreciable momentum flux into the MLT. Ray results for
                      different seasons reproduce some of the limits derived from
                      simple wave theory: that horizontal wavelengths shorter than
                      10 km tend to be removed by vertical reflection or
                      evanescence at the source and slower phase speeds are more
                      prone to critical level removal, leading to a preference for
                      waves with longer horizontal wavelengths and faster
                      ground-based phase speeds to reach the MLT. These findings
                      are compared to the wavelength scales currently resolved by
                      satellite limb and nadir sounders, highlighting wavelength
                      ranges currently measured and those currently unresolved. A
                      road map is developed for how current and future satellite
                      measurements can be combined to measure the full space-time
                      spectrum of gravity waves relevant to eddy flux deposition
                      and momentum forcing of the global MLT. In particular,
                      recommendations for new satellite measurement strategies
                      that fill current measurement gaps are provided.},
