Version Summary
Version Summary
Initial release of the 4 km MASIE NH product.
Overview
The Multisensor Analyzed Sea Ice Extent - Northern Hemisphere (MASIE-NH) products provide measurements of daily sea ice extent and sea ice edge boundary for the Northern Hemisphere and 16 Arctic regions in a polar stereographic projection at both 1 km and 4 km grid cell sizes. MASIE products include an ASCII text file of sea ice extent values in square km for each Arctic region, time series plots, and image files that visually show where the sea ice is.
Note: MASIE may look like several other sea ice products distributed at NSIDC and elsewhere, but its source data from the U.S. National Ice Center (USNIC) and intended uses are different. If intended and appropriate uses of the data are not clear after reading the documentation, please contact NSIDC User Services.

General Questions & FAQs
The regions differ slightly between the Sea Ice Index and the Multisensor Analyzed Sea Ice Extent - Northern Hemisphere (MASIE-NH). The two data sets are a source for sea ice extent, but they use different methods and data to estimate this parameter and their intended uses are also different.
For example, the MASIE-NH coastline has slight differences with the Arctic coastline available from the Toolik-Arctic Geobotanical Atlas.
