Abstract: A regional σ-model INMOM-Arctic has been prepared on the basis of the Russian ocean general circulation model INMOM (Institute of Numerical Mathematics Ocean Model) to reproduce the current state and short-term forecast of the Arctic Ocean (AO) hydrothermodynamics. The model is implemented in a rotated spherical coordinate system with the poles located at 60°E and 120° W on the geographic equator, which makes it possible to use a quasi-uniform resolution of ~ 3,7 km in the Arctic Basin. Data on temperature, salinity, horizontal velocity components and sea level taken from the CMEMS ocean products are used at the AO open boundaries. To take into account the tidal effect in the INMOM-Arctic model at open boundaries, the time series of the tidal sea level is set based on the data of the TPXO 9 atlas (TOPEX/Poseidon Global Tidal Model) with a spatial resolution of 1/30°. To calculate the atmospheric impact, the researches use the atmospheric circulation data from the Era 5 global reanalysis with a spatial resolution of 0,25×0,25° and with a temporal resolution of 1 hour. While estimating the accuracy in the temperature and salinity fields reconstructed by the INMOM-Arctic model on a seasonal scale the authors used the data from ARGO profiler buoys in retrospective simulations of the AO circulation for the period from March 1 to August 31, 2020, without assimilating observational data. They compared the estimates with similar ones from the CMEMS for the Arctic Basin for mean deviation and RMSD within close layers for temperature and salinity fields, respectively. In the temperature field, the INMOM-Arctic results have comparable and better indicators in terms of the mean deviation throughout the entire AO, and somewhat worse, in terms of the RMSD temperature in the upper 300 m layer, which, according to the INMOM-Arctic results, is slightly higher than according to the CMEMS. In deeper layers, on the contrary, in the INMOM-Arctic it is less or comparable. In the salinity field, the accuracy estimates obtained from the CMEMS data and the INMOM-Arctic model are comparable. In the near-surface layers, the RMSD in the INMOM-Arctic model is slightly higher than the analogous values obtained by CMEMS. However, the INMOM-Arctic model gives slightly better estimates in the mean deviations from the temperature and salinity measurements in depth. The RMSD between the simulated and measured sea level in the INMOM-Arctic model is 6 cm, while in the CMEMS it is 7 cm. In addition, the INMOM-Arctic model reproduces well the thermohaline state of the AO on synoptic scales, which is clear via comparison between simulation results and measured data of temperature and salinity profiles by the ARGO profiler buoys. The results of comparison between the simulated and observed data indicate that in the current implementation the INMOM-Arctic model using the proposed open boundary conditions makes it possible to reproduce correctly the circulation in the AO. In the next series of experiments, to improve the accuracy of simulations, the researchers implemented the procedure for assimilation of current satellite data on ice compactness and SST, based on the DART (Data Assimilation Research Testbed) software package (https://dart.ucar.edu/), using the EnKF — Ensemble Kalman Filter, in the INMOM-Arctic model. Thus, they proved that the assimilation of the satellite-measured SST and ice compactness makes it possible to improve the simulation results through the daily assimilation of satellite information.
