Land cover classes have been derived from bands of Sentinel-2 (bands 3 (green, 10m), 4 (red, 10m), 8 (near infrared, 10m), 11 (SWIR, 20m) and 12 (SWIR, 20m)) as well as...

Frozen state backscatter intensity was derived from Sentinel-1 acquisitions from December 2015 and 2016. By excluding the effects of liquid water content (acquisitions under...

Land surface features (water, wetland, tundra, and bare surfaces) were classified from TerraSAR-X with a resolution of 5 m for August 2012 and July 2014. The product is based on...

A circumpolar representative and consistent wetland map is required for a range of applications ranging from upscaling of carbon fluxes and pools to climate modelling and...

The vegetation map distinguishes between five tundra vegetation types, trees, and open water at the forest-tundra transition north of Inuvik, Northwest Territories, Canada. The...

This spatial dataset is quantifying soil organic carbon (SOC) and total nitrogen (TN) storage with their carbon to nitrogen ratio (C/N) in soils of the northern circumpolar...

The study was based on land cover classification of three almost cloud free Landsat-7 ETM+ satellite images. The acquisition dates are 27 July 2000 (path 131, rows 8 and 9) and...

Land cover maps are the basic data layer required for understanding and modeling ecological patterns and processes. The Circumpolar Arctic Vegetation Map (CAVM), produced in...

This digital database is the product of collaboration between the U.S. Geological Survey, the Alfred Wegener Institute for Polar and Marine Research Potsdam, Foothill College...

We mosaicked twelve LandSat-8 OLI satellite images taken during the summer of 2014, which were used in an object based image analysis (OBIA) to classify the landscape. We mapped...

Normalized difference vegetation index (NDVI) trend map was computed for the Alaskan Arctic Coastal Plain between 1999 and 2014. The decadal trend of each pixel was computed...

We mapped the occurrence of more than one million ice wedge polygons over a landscape of approximately 1,200 square kilometers, just south of Prudhoe Bay in northern Alaska,...

Ground ice melt caused by climate-induced permafrost degradation may trigger significant ecological change, damage infrastructure, and alter biogeochemical cycles. The...

One of the consequences of warming climate is rising ground temperatures and degradation of perennially frozen ground, permafrost. Thawing of near-surface permafrost can cause...

This raster dataset is a high-resolution mosaic of 4 Corona-KH4 satellite photos over the northern Seward Peninsula in Northwest Alaska dated to 28 July 1962. The mosaic covers...

The robust Theil-Sen regression algorithm was used to calculate trend parameters (slope, intercept, confidence intervals) on Landsat time-series stack in the north-east Siberian...

The product provides modeled mean annual ground temperatures (MAGT) at the top of the permafrost for the Northern Hemisphere at 1 km spatial resolution. Permafrost probability...

Weekly lake ice classifications distinguish grounded ice and floating ice in lakes based on Sentinel-1A and Sentinel-1B synthetic aperture radar time-series with a resolution of...

Vegetation height has been derived from Sentinel-1 satellite data acquired in VV mode with a resolution of 20 m. Vegetation height was estimated using an empirical model on...

Lake ice classifications distinguish grounded ice and floating ice in lakes based on Sentinel-1A and Sentinel-1B synthetic aperture radar time-series with a resolution between...
