ABoVE: Landsat-derived Annual Disturbance Agents Across ABoVE Core Domain, 1987-2012

Description

This dataset provides spatial data on disturbance agents of fire, insects, and logging in the Arctic Boreal Vulnerability Experiment (ABoVE) core domain at an annual time step from 1987-2012 and 30 m resolution. Using a time-series of Landsat data, the three disturbance types were identified by abrupt changes in Tasseled Cap (dTC) indices of brightness, greenness, and wetness. Disturbances were detected by a Continuous Change Detection and Classification (CCDC) harmonic regression model applied to the time series. The dTC indices and disturbance results are provided.

34 Casual agents of disturbance for the year 2006 in the ABoVE domain for tile BH19V15 (A) with the Tasseled Cap change (dTC) image in the same year for the same region (B). In the dTC image, Band_1 is change in brightness; Band_2 is change in greenness; Band_3 is change in wetness. The pixel resolution is 30 meters.
