Turbulence measurements during HALO-(AC)³ and AFLUX in the atmospheric boundary layer over the Arctic MIZ
We investigate the atmospheric boundary layer (ABL) structure over the marginal sea ice zone (MIZ) using AFLUX and HALO-(AC)³ measurements. We present vertical profiles of mean and turbulent ABL quantities obtained in springtime conditions during Arctic cold air outbreaks. However, the environmental...
