Short summary

This article presents a study for feasibility analysis of atmospheric wind measurement using a terahertz (THz) passive limb radiometer with high spectral resolution. The simulations show that line-of-sight wind from 40 to 120 km can be obtained better than 10 m s⁻¹ (at most altitudes it is better than 5 m s⁻¹) using the O₃, O₂, H₂O, and OI bands. This study will provide reference for future payload design.
