A quasi-daily pan-Arctic lead product derived from MODIS thermal infrared imagery
Polynyas and leads are key elements of the wintertime Arctic sea-ice cover. They play a crucial role in surface heat loss, potential ice formation and consequently in the seasonal sea-ice budget. We apply and evaluate different lead segmentation techniques base on sea-ice surface temperatures as mea...
