Description

This dataset provides daily lead maps for the Arctic as well as cyclone occurrence information based on a cyclone tracking algorithm (Akperov et al., 2020), which was applied to 6-hourly ERA5 (Hersbach et al., 2020) sea level pressure fields. The data is available on a daily time scale from 2002 to 2020 (leads only available for the months November to April) and has a horizontal resolution of 12.5 km². The purpose of the dataset is to analyze lead formation in the Arctic sea ice in response to cyclone passages. The lead data is based on the ArcLeads product (https://doi.org/10.1594/PANGAEA.955561) derived from MODIS thermal infrared imagery with 1 km² spatial resolution (Reiser et al., 2020).
