Abstract : This publication is the 19th edition of the Arctic sea-ice atlases prepared by the JIC. The atlas contains weekly charts depicting Northern Hemisphere and Great Lakes ice conditions and extent. The significant use of high resolution satellite imagery, combined with valuable ice reconnaissance data from various sources, has greatly improved the accuracy of these analyses. The purpose of this atlas is to provide the user with reliable weekly hemispheric ice analyses. Both Navy and NOAA personnel with considerable experience in sea-ice analysis prepare the analyses. The following procedures have been developed to ensure the quality of the products: a. Conventional shore station, ship, and aerial reconnaissance observations are plotted and evaluated. b. Satellite data from different sensors is compared and analyzed for ice information content. Table 1, located on the inside back cover, summarizes the data availability for 1992. c. A final product results from a and b. However, where insufficient data is available, an estimated boundary will be depicted. Meteorological data and computer generated ice drift vectors are used to determine the estimated ice position. (MM)
