Combined cyclone and sea-ice lead data for the Arctic for 2002 to 2020

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 (publication currently in preparation). 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).
