ICESat-2 altimeter data could be used to estimate sea ice freeboard and thickness values with a higher measuring accuracy than that achievable with data provided by previous altimeter satellites. This study developed an improved algorithm considering variable lead proportions based on the lowest point method to derive the sea surface height for the retrieval of Antarctic sea ice freeb... https://www.spidertattooz.com/2ft-LED-Strip-Light-Fixture-10-19-Watts-3000-Lumens-35K-40K-50K-120-277V/
