Summary: This dataset contains high-resolution nested simulations conducted over Andøya, Norway (ALOMAR) with UA-ICON (ua-icon-2.1) to be co-analyzed with mesospheric measurements collected during the NASA Vorticity Experiment (VortEx) sounding rocket campaign in March 2023. UA-ICON was configured with 180 vertical levels, a model top at 150 km, and a global horizontal resolution of R2B7 (~20 km). One-way nesting was applied to achieve progressively finer resolutions of R2B8 (~10 km), R2B9 (~5 km), R2B10 (~2.5 km), and R2B11 (~1.25 km). In the global domain (~20 km resolution), the large-scale dynamics during the campaign were specified by nudging to ECMWF operational analyses up to an altitude of 50 km. At resolutions finer than 5 km, UA-ICON resolves a significant portion of the gravity wave (GW) spectrum. Consequently, GW and convective parameterizations were disabled progressively, starting from domain DOM3 (~5 km), to isolate the effects of resolved GWs. The simulations show satisfactory agreement with observations, highlighting the model’s capabilities for investigating the dynamics in the MLT region.
