Satellite-derived sea ice motion data: daily-maps (DM) and swath-to-swath (S2S)

Remotely sensed ice motion is a crucial component in sea, lake, or river ice research. Over the past few decades, the ice movement has been detected and retrieved predominantly through the application of the Maximum Cross-Correlation (MCC) technique by analyzing the overlapped consecutive satellite images. Traditionally, ice motion products have been derived from daily averaged satellite imagery, commonly referred to as 'daily-map' (DM) ice motion. This DM ice motion product has gained widespread usage in sea ice studies due to its inherent timescale and extensive coverage. Recently, a new approach known as the swath-to-swath (S2S) method has emerged, deriving ice motion from individual satellite swath pairs. The S2S ice motion product has proven valuable in sea ice kinematics research, revealing a robust relationship between ice kinematics and thickness, characterized by its diverse timescale. Consequently, these two types of satellite-derived ice motion products contribute distinct perspectives to ice kinematics research. The latest generation of NOAA's Geostationary Operational Environmental Satellites (GOES), specifically the GOES-R Series, offers sea/lake/river ice observations at a relatively high resolution. A recent development involves the MCC approach generating a new DM ice motion product with a 2 km resolution using GOES-R reflectance imagery (0.5 km resolution). This ice motion dataset holds potential for final users engaged in analyzing small-scale sea/lake/river ice status and its changes.
