AB: Passive microwave sea ice concentration fields provide one of the longest running and most consistent records of changes in sea ice. Scatterometer data is a more recently developed product, but now provides several years of sea ice data. Resolution enhancement techniques can provide much higher effective resolution (~10 km) than are available from standard scatterometer and passive microwave fields (25-50 km). Here, we combine sea ice extent fields from enhanced resolution scatterometer data with sea ice concentration fields derived from enhanced resolution passive microwave brightness temperatures to create a merged field that potentially yields higher quality concentration and extent retrievals. The use of multiple sources can yield confidence level estimates that provide pixel-by-pixel insight into the reliability of sea ice fields.
