Home > SEA ICE documentation

The sea ice group is part of the Marine Modeling and Analysis Branch of the Environmental Modeling Center. Our responsibility, loosely speaking, is ice anywhere in the world, particularly ice which is floating on water. We start with remote sensing, analysis, and data assimilation of sea ice information to obtain the best possible (automated) estimates of current sea ice conditions. Once we have sea ice conditions, which are of interest in their own right, we then use the information to improve the weather forecast model(s), and to run sea ice forecast models.

We emphasize automated regarding our analysis because our work supports sea ice analysis by the NWS Alaska Region, and a wide variety of users in the US and world. These users bring other data sets and methods to the analysis which may not be automatable, and can result in significant improvements in the final products relative to the strictly automatic. You may see the current day's automated analysis at http://polar.ncep.noaa.gov/seaice/Analyses.html. The 3 times per week Alaska Region analysis is at http://pafc.arh.noaa.gov/ice.php.
