Evaluation of Sea Surface Wind Products from Scatterometer Onboard the Chinese HY-2D Satellite

An 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...

Impact of Gridded Surface Wind/wind-stress Data Set Constructed by Satellite Scatterometer Data

Interannual 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...

Polar Sea Ice Monitoring Using HY-2A Scatterometer Measurements

A sea ice detection algorithm based on Fisher’s linear discriminant analysis is developed to segment sea ice and open water for the Ku-band scatterometer onboard the China’s Hai Yang 2A Satellite (HY-2A/SCAT). Residual classification errors are reduced through image erosion/dilation techniques and sea ice growth/retreat constraint methods. The arctic sea-ice-type classification is estimated via...

Evaluation of HY-2A Scatterometer Wind Vectors Using Data from Buoys, ERA-Interim and ASCAT during 2012-2014

The first Chinese operational Ku-band scatterometer on board Haiyang-2A (HY-2A), launched in August 2011, is designed for monitoring the global ocean surface wind. This study estimates the quality of the near-real-time (NRT) retrieval wind speed and wind direction from the HY-2A scatterometer for 36 months from 2012 to 2014. We employed three types of sea-surface wind data from oceanic moored b...
