Dataset: IMS Daily Northern Hemisphere Sea Ice Coverage

About this Dataset

IMS Daily Northern Hemisphere Sea Ice Coverage

Context

MASIE-NH stands for the Multisensor Analyzed Sea Ice Extent – Northern Hemisphere. It is similar to the Sea Ice Index (SII) product in that it is easy to use and gives a graphical view of ice extent in various formats. However, it relies more on visible imagery than on passive microwave data, so the ice edge position will generally be more accurate than that of the Sea Ice Index. The input is the daily 4-km sea ice component of the National Ice Center (NIC) Interactive Multisensor Snow and Ice Mapping System (IMS) product.

Content

Northern Hemisphere-wide sea ice coverage.

The initial MASIE product had a nominal gridded resolution of:

masie_4km_allyears_extent_sqkm.csv: 4 km x 4 km that spans 01 October 2006 to present at a daily resolution.
masie_1km_allyears_extent_sqkm.csv: as of 02 December 2014, a 1 km x 1 km gridded product is also available to present at a daily resolution.
