Annual Arctic Vegetation Resilience from MODIS, 2000-2019

MODIS-derived Annual Vegetation Resilience, 2000-2019 provides estimates of vegetation recovery rates across the Arctic Boreal Vulnerability Experiment (ABoVE) core domain. The dataset spans 20 years and covers 175 grid tiles at a 300-meter spatial resolution. It was produced by ORNL_CLOUD using a Bayesian dynamic linear model on Terra MODIS EVI time series.

Use Cases

• Analyzing spatial patterns of vegetation recovery rates from climate perturbations using the mean resilience raster.
• Assessing uncertainty in resilience estimates by comparing the provided upper and lower boundary GeoTIFFs.
• Modeling long-term trends in Arctic and boreal ecosystem stability across the 2000-2019 time period.
• Integrating 300-meter resolution resilience maps with other ABoVE domain datasets for regional vulnerability studies.

Strengths

• Provides a 20-year time series (2000-2019) for analyzing long-term trends.
• Covers a large, ecologically critical region across 175 specific ABoVE grid tiles.
• Derived from a consistent, well-documented satellite product (Terra MOD13Q1v061 EVI).
• Includes uncertainty quantification through upper and lower boundary estimates alongside the mean.

Limitations

• Spatial resolution is fixed at 300 meters, which may be coarse for local-scale analysis.
• Conflicting last updated dates exist between sources (2019-12-31 and 2026-03-12).
• Specific column names and dataset size information are not provided by any source.
