摘要

TKE dissipation rate can be estimated from VHF/UHF Doppler radars. The currently used model for stably stratified conditions seems to be challenged by comparisons with UAV measurements. An alternative model derived for weakly stable conditions (Basu and Holtslag, EFM, 21, 1273, 2021) provides better agreements for shear-generated turbulent layers.
