AB  - The meridional winds in the stratosphere and middle layer play an important role in atmospheric dynamics and aviation. However, directly measuring wind within this altitude range is difficult. This dataset utilizes gradient equilibrium wind theory and temperature and pressure observed by SABER instruments to establish a monthly average meridional wind dataset from 2002 to 2019, with an altitude of 18-100 km and latitude of 50 ° S-50 ° N. Tidal aliases above 80 kilometers of the equator are replaced by monthly average meridional winds measured by meteor radar at 0.2 ° S. This dataset (named BU) was validated by comparing the meridional winds with MERRA2 (MerU), UARP (UraU), HWM14 empirical model (HwmU), meteor radar (MetU), and lidar (LidU) at approximately 50 ° N to 29.7 ° S at 7 stations. The advantage of the global BU dataset lies in its large vertical range (from the stratosphere to the lower thermosphere) and consistent time series within 18 years (2002-2019). The data from BU is useful for studying the temporal variation from season to several decades within the range of 50 ° S-50 ° N. It can also serve as the background wind for atmospheric wave propagation.
