DEM of the Global Change Research Wetland (GCReW) site generated using the LEAN (LiDAR Elevation Correction with NDVI) method. LEAN uses ground measurements of elevation and NDVI in a multivariate linear regression model to estimate vertical bias.

Global monthly gross primary productivity (GPP) of biomass for December 2016.

Location of wetland sites in the Mississippi River Delta where biomass measurements were collected in the Pre-Delta-X Spring and Fall 2015 Campaigns.

Searching for the term remote sensing and words related to invasive species (invasive, nonnative, exotic, or nonindigenous) in Google Scholar reveals an increasing number of publications each year using these terms.

Vegetation point-intercept (VPI) any-hit cover metric data were combined with Landsat imagery to develop fractional maps of any-hit cover for four aggregated plant functional types (PFTs);  shrubs bryophytes, lichen, and herbs for the upland tundra area of the Y-K Delta, Alaska. VPI data were collected from plots in areas burned in 1971, 1985, 2005, and 2015.

Concurrent woody and herbaceous vegetation changes between the 1982-1991 and 2004-2013 decades of the Sudano-Sahel region of Africa. (A) Map of vegetation change categories. (B) Chart showing the conceptual position and the relative abundance of each category in a 2-D space.

GEDI data will help further refine our understanding of the carbon cycle and atmospheric concentrations of carbon dioxide (CO2).
