Regional climate model simulations (CCLM 5km) for 2017-2020 at Cape Baranova (Severnaya Zemlya, Siberia)

Measurements of the atmospheric boundary layer (ABL) structure for three years (Oct. 2017 – Aug. 2020) were performed at the Russian observatory “Ice Base Cape Baranova” (79.280°N, 101.620°E). ABL measurements were used for verification of the regional climate model COSMO-CLM (CCLM) with 5 km resolution for 2017-2020. CCLM was run with nesting in ERA5 data in a forecast mode for the measurement period. Model output is available every 1h. In the vertical, the model extends up to 22 km with 60 vertical levels. The observatory is located on Bolshevik Island, which is the southernmost island of the Severnaya Zemlya Archipelago. Flow channeling during conditions of a stable boundary layer occur due to the topography on both sides of Shokalsky Strait between Bolshevik Island and October Revolution Island. For more details and the exact description of the methods see Heinemann et al. (2022).
