NASA SCP Arctic and Antarctic Ice Extent from QuikSCAT, 1999-2004
Entry ID:
NSIDC-0265
Summary
Abstract:
This data set provides sea ice extent for the Arctic (60-90 degrees North) and Antarctic (52-90 degrees South) in Scatterometer Image Reconstruction (SIR) binary image format, along with ASCII text files containing latitude and longitude coordinates along the sea ice edge, and browse images of SIR files in Portable Network Graphics (PNG) format. Ancillary products include daily-averaged total sea ...

Quality
Sea ice extent images were manually checked for spatial and temporal consistency. NSIDC noticed some inconsistencies in the ice extents from QuikSCAT. Slice images appear much noisier than egg images in the Arctic, particularly in 2003 and 2004. Antarctic ice extents should match well between QuikSCAT and Special Sensor Microwave/Imager (SSM/I) using a 30% ice concentration threshold, but a ...
