Sea ice extent mapping using Ku band scatterometer data
Although spaceborne scatterometers such as the NASA scatterometer have inherently low spatial resolution, resolution enhancement techniques can be used to increase the utility of scatterometer data in monitoring sea-ice extent in the polar regions, a key parameter in the global climate. The resolution enhancement algorithm produces images of A and B, where A is the normalized radar backscatter ...
متن کاملAn assessment of Sea Ice Extent Retrieval Based on HY-2A Scatterometer Data Using Other Satellite Products
A sea ice extent retrieval algorithm over the polar area based on scatterometer data of HY-2A satellite has been established. Four parameters are used for distinguishing between sea ice and ocean with Fisher’s linear discriminant analysis method. The method is used to generate polar sea ice extent maps of the Arctic and Antarctic regions of the full 2013-2014 from the scatterometer aboard HY-2A...
متن کاملArctic Sea Ice Extent Prediction
Climate change is a pressing and present issue which has come to be at the forefront in the last few decades. As such, understanding climate change is of utmost importance. In addition to environmental impact, these changes will have social and economic ramifications as these changes will affect the way in which we utilize land and sea resources in the future. The minimum annual arctic sea ice ...
متن کاملIterative Estimation of Antarctic Sea Ice Extent Using SeaWinds Data
Polar sea ice extent is an important input to global climate models and is considered to be a sensitive indicator of climate change. An algorithm has previously been developed for sea ice extent detection using data from the NASA scatterometer (NSCAT). This paper discusses the extension of that algorithm to data from SeaWinds on QuikSCAT. Due to differences in the two instruments, several modif...
متن کاملInterannual Variability in Weddell Sea Ice from Ers Wind Scatterometer
ERS-1/2 SAR and Wind Scatterometer data are analyzed together with DMSP SSM/I microwave radiometer data to investigate interannual variability in Weddell Sea ice and summer melt signatures during the period 1992-1997. Simultaneous SAR and Scatterometer images were obtained during a February 1995 cruise of the H.M.S. Endurance and aerial photographs collected for validation of the satellite obse...
