分析了从动力学探索者2号上的风和温度实验中测量到的中性热层纬向风，以提供中性热层超级旋转的测量。这些数据是在当地时间从赤道到北纬40度的10度范围内平均得出的。结果表明，赤道东侧平均风速约为18m/S，中纬度平均西风约为18m/100m。在数据库的高度范围内(200至700公里)，没有发现任何明显的海拔相关性证据。将我们的数据在所研究的纬度带上平均，表明热层的净自转。这一结果与King-Hele和Walker根据卫星阻力分析报告的超自转值不一致。
Neutral thermospheric zonal winds measured from the Wind and Temperature Experiment on Dynamics Explorer 2 have been analyzed to provide a measure of the superrotation of the neutral thermosphere. The data were averaged in local time in 10 degree bands from the equator to 40 degrees latitude. The results show an average wind velocity on the order of 18 m/s to the East at the equator and a westward wind of the same magnitude at mid latitudes. Within the range of altitudes of the data base (200 to 700 km) no evidence of any significant altitude dependence was found. Averaging our data over the latitude bands studied indicates a net corotation of the thermosphere. This result is not in agreement with the superrotation value reported by King-Hele and Walker on the basis of satellite drag analysis.
