Continuous Global Mangrove Dynamics (CGMD) is a suite of global mangrove datasets designed to support long-term monitoring of mangrove extent, canopy structure, degradation, recovery, and blue carbon dynamics.
The current release includes annual mangrove extent and fractional canopy cover datasets from 1984 to 2023, generated from long-term Landsat time series.

Global Annual Mangrove Extent (1984-2023)
The CGMD-Extent30 (Continuous Global Mangrove Dynamics-Annual Mangrove Extent at 30-m resolution) dataset provides global annual mangrove extent from 1984 to 2023. The dataset is distributed as a single Earth Engine FeatureCollection, with each feature representing a mapped mangrove polygon for a specific year. The dataset … annual coastal forest-biomass global landsat-derived landuse-landcover -
Global Annual Mangrove Fractional Canopy Cover (1984-2023)
This dataset provides global annual mangrove fractional canopy cover (FCC) at 30-m spatial resolution from 1984 to 2023 to support large-scale analyses of long-term mangrove dynamics, including canopy degradation and recovery, blue carbon assessment, and coastal ecosystem monitoring. FCC quantifies the proportion of each Landsat … annual coastal forest-biomass global landsat-derived mangrove
