The data set currently contains ice velocity data for the winter of 2000-2001 and 2005-2006, 2006-2007, and 2007-2008 acquired from RADARSAT-1 InSAR data from the Alaska Satellite Facility (ASF), and a 2008-2009 mosaic derived from the Advanced Land Observation Satellite (ALOS) and TerraSAR-X data. Note: Although this data set has been screened for anomalously large errors, at this stage they are Version 1 and some significant errors may persist (>20 m/yr). In addition, these data are considered provisional pending a review by the MEaSUREs program.

Products include an ASCII text file of sea ice extent values in square km over the entire Northern Hemisphere with 16 separate Arctic regions identified, time series plots of the 16 regions, and image files that visually show where the sea ice is. The MASIE-NH imagery are provided at a nominal 4 km resolution. The input data comes from the 4 km Interactive Multisensor Snow and Ice Mapping System (IMS) snow and ice product produced by the National Ice Center (NIC). NIC utilizes visible imagery, passive microwave data, and NIC weekly analysis products to create their data product. The MASIE-NH products are distributed in a number of formats including ASCII text, GeoTIFF, PNG, shapefiles, and Google Earth files and are available from 01 October 2006 to the present. The most recent days worth of imagery plus the ASCII text data file are provided via the MASIE Web site. A complete archive of the imagery and data can be obtained via FTP. Note: MASIE may look like several other sea ice products distributed at NSIDC and elsewhere, but its source data 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.' description_attribution: http://nsidc.org/data/g02156.html display_name: 'Multisensor Analyzed Sea Ice Extent - Northern Hemisphere (MASIE-NH)' doi: 10.7265/N5GT5K3K end_time: ~ identifier: nsidc-g02186 lat_max: 90 lat_min: 0 lon_max: 180 lon_min: -180 name: 'Multisensor Analyzed Sea Ice Extent - Northern Hemisphere (MASIE-NH)' native_id: G02186 processing_level: ~ publication_year: ~ release_dt: 2010-12-14T00:00:00 scale: ~ scope: ~ spatial_extent: ~ spatial_ref_sys: ~ spatial_res: ~ start_time: 2006-10-01T00:00:00 temporal_extent: ~ temporal_resolution: ~ type: dataset uri: /dataset/nsidc-g02186 url: http://nsidc.org/data/G02186 variables: ~ version: ~ vertical_extent: ~ display_name: advanced-land-observing-satellite/phased-array-type-l-band-synthetic-aperture-radar href: http://52.38.26.42:8080/platform/advanced-land-observing-satellite/instrument/phased-array-type-l-band-synthetic-aperture-radar.yaml instrument_identifier: phased-array-type-l-band-synthetic-aperture-radar location: ~ parents: [] platform_identifier: advanced-land-observing-satellite type: instrument_instance uri: /platform/advanced-land-observing-satellite/instrument/phased-array-type-l-band-synthetic-aperture-radar
