HWM Neutral Wind Model from NSSDC
Entry ID: HWM87_MODEL

[ Update this Record ]

Summary
Abstract: The HWM87 is an empirical model of the horizontal neutral wind in the
upper thermosphere analogous to the MSIS model for neutral temperature
and density. It is based on wind data obtained from the Atmosphere
Explorer E and Dynamics Explorer 2 satellites. A limited set of vector
spherical harmonics is used to describe the zonal and meridional wind
components. The data base was not adequate to ... View entire text
