Seasonal Ice Zone Observing Network (SIZONET)


  The remote sensing component of SIZONet comprises near-realtime delivery of data through the Geographic Information Network of Alaska (GINA) and the Alaska Ocean Observing System (AOOS). Data sets include thermal-IR and visible range imagery from MODIS and AVHRR received on-site, Radarsat Synthetic Aperture Radar (SAR, through 2008), QuikScat scatterometer and passive microwave satellite data. Among other products, we distribute imagery through an interface designed for low-bandwidth access in coastal villages and products such as the onset of melt or freezing and snow-depth distribution by processing downlinked data in collaboration with our Phase I partners at NASA-Goddard and JPL (Nghiem et al. 2006; Markus et al. 2006). Such data are of great value for planning of field campaigns and allow us and other projects to target areas where ground-based observations are particularly useful in the context of validation and improvement of retrieval algorithms. We are also compiling data sets that complement our airborne and ground-based surveys and are currently evaluating how to best post such information (see, e.g., http://gi.alaska.edu/~cpetrich/RADAR-relevant/) to provide framing information for users of our data and products.
