This dataset provides methane fluxes from hot-spot and non-hot spot differing surfaces at Big Trail Lake (BTL) in the Goldstream Valley near Fairbanks, AK, USA. Measurements...

The Boreal and Arctic Wetland and Lake Dataset (BAWLD) provides estimates of fractional land cover of 19 land cover classes within 0.5° ×0.5° grid cells. The total area of the...

This dataset provides Level 1 radiance and Level 2 surface reflectance measured by the Airborne Visible/Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) instrument...

This data set provides the distribution of thermokarst landscapes in the boreal and tundra ecoregions within the northern circumpolar permafrost zones. This dataset provides an...

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...

Soils in the northern high latitudes are a key component in the global carbon cycle; the northern permafrost region covers 22% of the Northern Hemisphere and holds almost twice...

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...

This dataset provides observations of atmospheric methane (CH4) amounts obtained from observations collected by several current and historical satellite instruments. Methane is...

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...

Seasonal and interannual variations in global wetland area is a strong driver of fluctuations in global methane (CH4) emissions. Current maps of global wetland extent vary with...

The GIS database contains the data of aufeis (naleds) in the Indigirka River basin (Russia) from historical and nowadays sources, and complete ArcGIS 10.1/10.2 and Qgis 3*...

The GIS database contains the data of aufeis (naled) in the Chukotka region from historical and nowadays sources, and complete ArcGIS 10.1/10.2 and Qgis 3* projects to view and...

The pan-Arctic Permafrost-Region Lake-DOC version1 database contains surface water samples of lakes in the permafrost regions of Alaska (49.3 %), Canada (24.2 %), Greenland (3.2...

We identified all lakes larger than 10 hectares (ha) that drained completely or partially (greater than 25 %) between 1955 and 2017 using historical (original) USGS topographic...

A detailed attributed point feature shapefile of 1247 pingo locations was manually assembled from a 5m resolution digital surface model (DSM) derived from an airborne...

A detailed attributed point feature shapefile of 6059 pingo locations in a 3.5 × 10⁶ km² region of northern Asia was manually assembled from 1:200 000 scale Russian...

We compiled a near-surface permafrost temperature dataset from 72 monitoring stations in Alaska using data collected by the U. S. Geological Survey, the National Park Service,...
