A perspective of one study plot at the forest-tundra ecotone with mature spruce trees transitioning into short-stature trees and low-stature deciduous shrubs.
Terrestrial lidar scanning point cloud data are available for research plots in the Brooks Range of Alaska.
Gridded Land, Vegetation, and Ice Sensor (LVIS) instrument data products at 25 m spatial resolution over the Mondah Forest (left) and Mabounie (right) sites in Gabon.
NASA's airborne Land, Vegetation, and Ice Sensor (LVIS) instrument was used to collect inventory data for Gabon's forests.
Land cover classification at 30 m resolution for the Colombian Amazon for the year 2016.
New maps of land cover classes for the Colombian Amazon were derived from changes in surface reflectance.
Relationship between the quantum yields of fluorescence (Ft) and photosystem II (Fv/Fm) sampled Picea glauca needles in Alaska (A) and Abies grandis needles in Idaho (B). Modeled (A) and observed (B) irradiance is indicated by the coloration of points; grey points in individual sampling period panels show observations from all periods for reference. Plots of sampling periods aligned with the timing of satellite overpasses are outlined in green (A) and blue (B) boxes, respectively.
In situ measurements of needle-level chlorophyll fluorescence and other irradiance products are now available.

In blue, the extent of the Fall 2016 channel bathymetry survey in the main channels of the Atchafalaya and Wax Lake Deltas.
Bathymetry data are available for a major channel of the Mississippi River Delta.
Collecting in situ spectral reflectance data with the Analytical Spectral Devices (ASD) FieldSpec 3 on the Atchafalaya River.
A new dataset provides hand-held spectrometer measurements collected across the Atchafalaya and Terrebonne basins.
Collection of surface water samples in the Atchafalaya River for total suspended solids (TSS) analysis.
TSS was sampled across a variety of hydrodynamic and physical settings to represent basin heterogeneity.
