(abstract) Alaska SAR Facility Ocean and Ice Data Opportunities Over the Next Decade

The Alaska SAR Facility (ASF) is currently processing data from four satellites. All of these generate SAR data useful for ice observations and three of them generate data useful for ocean observations. The data sets from these satellites are available to approved US and other investigators although the approval mechanisms are different. More satellites are planned. These will carry SAR instruments of increased capability for ocean and ice observations. We will discuss the anticipated situation for access to these data sets by the scientific community and we will speculate on what the major oceanographic applications may be.

ASF archive issues: Current status, past history, and questions for the future

The Alaska SAR Facility (ASF) collects, processes, archives, and distributes data from synthetic aperture radar (SAR) satellites in support of scientific research. ASF has been in operation since 1991 and presently has an archive of over 100 terabytes of data. ASF is performing an analysis of its magnetic tape storage system to ensure long-term preservation of this archive. Future satellite missions have the possibility of doubling to tripling the amounts of data that ASF acquires. ASF is examining the current data systems and the high volume storage, and exploring future concerns and solutions.
