LES results to accompany measurements at the POLARSTERN Research Vessel during the PASCAL field campaign on 7 June 2017

DOI

This archive contains Large Eddy Simulation (LES) results to accompany measurements made at the Polarstern Research Vessel during the PASCAL field campaign on 7 June 2017, when the Polarstern was located in the sea ice north of Svalbard. The Dutch Atmospheric Large-Eddy Simulation model (DALES) was applied, adopting a Lagrangian framework that follows domains as embedded in relatively warm air masses as they moved towards the Polarstern. The simulated doubly periodic domain has a size of 2.56x2.56x1.28 km, discretized at a resolution of 20x20x10 m. The domain arrives at the Polarstern at 10:48 UTC on 7 June 2017 coinciding with a radiosonde release. The Polarstern was located at 10.93 E, 81.18 N.The large-scale forcings are derived from ECMWF analysis and forecast data. Adjustments were made in the initial profiles to correct for biases in the analysis state concerning inversion height, mixed layer temperature and the presence of Specific Humidity Inversions (SHI). This adjustment technique is described in detail by Neggers et al. (2019, doi:10.1029/2019MS001671). Two experiments are included in this archive: a control experiment including an SHI, and an additional experiment with the SHI removed. The configuration of the experiments is fully described by Egerer et al. (2020, doi:10.5194/acp-2020-584).
