Entry ID: CN_NADC_2014-2015_Arctic_Greenland_OLI_Description
Publish Date: 2016-11-29
Author: , Cheng Xiao
Keywords: Greenland, RS image
Location: Greenland
Dataset: Files(1) Filesize(11.7 MB)
Summary: The research team of the project has utilized the abilities of the Landsat-8 OLI image bands to create a 30-m image mosaic of Greenland from 108 individual scenes acquired during June to August in 2014 and 2015. Firstly, we calculated solar elevation angle for each pixel individually. Secondly, this solar elevation angle is the main factor for calculation of planetary reflectance. Then, we calculated a piecewise function to project the spectral reflectance of every single band to RGB values. Finally, the team used all multispectral (Bands 2-4) OLI scenes at 30m resolution for a full mosaic. This is a latest image mosaic for Greenland.

Entry ID: CN_NADC_1999-2003_Polar_regions_Antarctica_ETM_MODIS_blue_ice
Publish Date: 2015-04-27
Keywords: Antarctic, blue ice, ETM, MODIS
Location: Circumpolar
Dataset: Files(1) Filesize(88.0 MB)
Summary: Blue ice areas (BIAs) and their geographical distribution in Antarctica were mapped using Landsat-7 ETM+ images obtained during austral summers of 1999-2003 covering the north area of 82.5°S, and snow grain size image of MODIS-based Mosaic of Antarctica (MOA) dataset acquired during the 2003-2004 austral summers from 82.5°S to the South Pole. The results estimated BIAs to occupy 234,549 km2, or 1.65% of the continent. The BIAs were scattered widely over coastal or mountainous regions of the continent but were generally located in Victoria Land, the Transantarctic Mountains, Dronning Maud Land, and the Lambert Glacier basin. The surface slope of most of the BIAs was less than 5 degrees, and only 5.5% of the BIAs had slopes of more than 5 degree primarily located in the Transantarctic Mountains and Victoria Land. The ice velocities of approximately 92.92% of the BIAs were less than 500 meters per year, while ~84% of BIAs exhibited ice velocity of less than 200 meters per year mainly located in the Ross, Shackleton, Amery, Riiserlarsen and Ronne Ice Shelves closely associated with glacier dynamics. The BIAs product has been distributed by National Snow and Ice Data Center of USA. This paper has been published by Annals of Glaciology, and was financially supported by Chinese Polar Environment Comprehensive Investigation and Assessment Program and National Natural Science Foundation of China.

Publish Date: 2015-03-16
Keywords: iceberg calving, Antarctic
Location: Antarctica
Dataset: Files(1) Filesize(2.2 MB)
Summary: This data sets provides a direct measurements of all icebergs larger than 1 km² calving from the entire Antarctic coastline between 2005 and 2011. Mass loss due to iceberg calving is estimated by manually delineated annual cumulative area calved based on ENVISAT Advanced Synthetic Aperture Radar (ASAR) images from the Augusts of 2005, 2006, 2007, 2008, 2009, 2010 and 2011 with visual interpretation and spatial adjustment, in combination with estimates of the average ice thickness of the calved regions from ICESat and IceBridge data. 579 iceberg calving events, ranging in size from 1 to 3115 km², are measured over the 7-year study period.
