AB: Since its inception in 1998, the NOAA Interactive Multisensor Snow and Ice Mapping System (IMS) has sought to provide the most timely, accurate and reliable snow and ice cover gridded data to a broad user community. The output of this product has improved incrementally in resolution, timeliness, and accuracy, with the most notable upgrade of IMS Version 2 (V2) in February 2004. New output requirements, the need for metadata, satellite advancements, and the desire for a broader suite of snow and ice variables mandates another significant overhaul in the IMS system requirements. The intent of the IMS Version 3 (V3) is to improve the output accuracy, timeliness, resolution, metadata, cost, and add flexibility for future enhancements. The IMS production is scheduled for an operational transition to the National Ice Center (NIC) in March 2008. The NIC currently uses a vector-based GIS production system for sea ice charting, which is in contrast to the current raster-based production of the IMS. Integration of the IMS into a vector-based system should allow many of the previously mentioned improvements in the output, while integrating NIC systems. While production will be vector-based, output products will include a more diverse yet integrated collection of raster products. Raster products remain the preferred input source for weather and climate models which are the primary users of the IMS. While this alteration from raster-to-vector based analysis will likely provide significant improvements, care must be taken in the transition from one production methodology to another to preserve its benefit to numerical weather prediction and climate monitoring.
