Remote sensing quantifies widespread abundance of permafrost region disturbances across the Arctic and Subarctic, Datasets ...

Here we quantify the abundance and distribution of three primary permafrost region disturbances (PRD; lakes and their dynamics, wildfires, retrogressive thaw slumps) using trend analysis of 30-m resolution Landsat imagery from 1999-2014 and auxiliary datasets. The dataset spans four continental-scal...

Description
Summary:Here we quantify the abundance and distribution of three primary permafrost region disturbances (PRD; lakes and their dynamics, wildfires, retrogressive thaw slumps) using trend analysis of 30-m resolution Landsat imagery from 1999-2014 and auxiliary datasets. The dataset spans four continental-scale transects in North America (Alaska, Eastern Canada) and Eurasia (Western Siberia, Eastern Siberia), covering 2.3M km² or ~10% of the permafrost region. This data publication contains geospatial vector files (polygons) of the perimeters of PRD.The data are subdivided by PRD type (lakes, wildfire, retrogressive thaw slumps) and further subdivided by study region (T1_WS, T2_ES, T3_AK, T4_EC).T1_WS: Western SIberiaT2_ES: Eastern SiberiaT3_AK: AlaskaT4_EC: Eastern CanadaThe datasets are documented in detail in the linked document (Nitze_etal_2018: Data Documentation v1.0). ... : Vector format: ESRI ShapefileProjection: Geographic WGS84 (EPSG:4326)Vector type: Polygon ...
