“…Finally, further improvements were made upon the model [195] by incorporating information derived from satellite drag measurements (model DTM). The details of these various models as well as relevant comparisons with other models and data-sets have been discussed in the papers referenced, as well as by others [196][197][198][199]. It is noteworthy that this sequence of global thermospheric temperature models is the only one in existence that is derived from the direct measurements of kinetic temperatures, rather than inferences based on constituent density measurements.…”

was used to determine the thermospheric neutral motions in the auroral zone. These measurements were compared with simultaneously measured ion drifts, obtained with the Chatanika incoherent backscatter radar [73], see Figure 3. This comparison showed that the neutral wind in the evening sector flowed in a generally sunward direction, in correspondence with the direction of ion convection, but opposite to that which would be expected from a consideration of solar heating alone. Further analysis of the 1972-73 data set [74] was presented, together with a modelling study of the auroral momentum equation, to suggest that ion drag was playing an important role in establishing the sunward neutral wind. This work was in accord with independent experimental results using rocket chemical release vapour trail analysis [75-77]. A more recent paper [78] has compared the optical meridional wind measurements made in Alaska during 1972 with determinations of the same parameter made using the Chatanika incoherent scatter radar. Reasonable agreement was found between the two (optical and radar) techniques, both for averaged wind patterns and for simultaneously observed winds from individual nights; this is illustrated in Figure 4. The experimental results from this study were also compared with the predictions of the NCAR-TGCM; the comparison indicated reasonable agreement and was suggestive of a possible heat source poleward of Chatanika.
