Group: Summary

   The Arctic and Antarctic Research Institute (AARI) in St. Petersburg, Russia, 
   produces sea ice charts for safety of navigation in the polar regions and for 
   other operational and scientific purposes. Arctic charts from 1933 through 
   2006 are collected in this data set. Chart frequency and spatial coverage 
   varies, but charts were compiled every 10 days during the navigation season, 
   and monthly for the rest of the year, over most of the series. There is a gap 
   with no charts from 1993 through 1996. Chart coverage focuses on the Northern 
   Sea Route, although later charts extend into the central Arctic.  The charts 
   were compiled from a variety of data sources, with heavy reliance on regular 
   reconnaissance flights for most of the series until 1992.

   Early paper charts were digitized, and the entire series, including later 
   charts that were produced entirely digitally, were converted to Sea Ice Grid 
   (SIGRID) format at AARI. AARI provided code to read the SIGRID data and 
   convert it to a format close to Equal Area Scalable (EASE)-Grid. NSIDC 
   completed the conversion to EASE-Grid. The EASE-Grid is in a Lambert 
   equal-area projection with 12.5 km cell size. Total ice concentration, as well 
   as partial concentrations for multiyear, first-year, new/young ice (ice 
   younger than first-year ice), and fast ice, are given in EASE-Grid (binary), 
   SIGRID (ASCII), and browse (PNG) files. Data are available via FTP. This data 
   set replaces and updates the previous data set, AARI 10-Day Arctic Ocean 
   EASE-Grid Sea Ice Observations (nsidc-0050, discontinued December 2007), and 
   the Russian Arctic charts on the Environmental Working Group Joint 
   U.S.-Russian Arctic Sea Ice Atlas (http://nsidc.org/data/g01962.html).

   Access to the data is unrestricted, but users are encouraged to register for 
   the data. Registered users will receive e-mail notification about any product 
   changes.
