从大气探索者E号和动力学探索者2号卫星获得的热层风数据已被用于生成一个热层上层的经验风模型，该模型类似于MSIS温度和密度模型，使用一组有限的矢量球谐函数。该模式限于大约220公里以上，在那里数据覆盖范围最好，风随高度的变化因粘性而减少。目前的数据库还不足以检测太阳活动周期（F10.7）的影响，但确实包括了磁活动的影响。中低纬度的数据被复制得很好的模式和出版的地基结果相比，毫不逊色。极地涡旋是存在的，但不是全部细节。
Thermospheric wind data obtained from the Atmosphere Explorer E and Dynamics Explorer 2 satellites have been used to generate an empirical wind model for the upper thermosphere, analogous to the MSIS model for temperature and density, using a limited set of vector spherical harmonics. The model is limited to above approximately 220 km where the data coverage is best and wind variations with height are reduced by viscosity. The data base is not adequate to detect solar cycle (F10.7) effects at this time but does include magnetic activity effects. Mid- and low-latitude data are reproduced quite well by the model and compare favorably with published ground-based results. The polar vortices are present, but not to full detail.
