Example subset of aboveground biomass density (AGBD; Mg ha-1) predictions from the GEDI Level-4A footprint product over Northern California, U.S., spanning April to July 2019. GEDI footprints are spaced 60m along-track and 600m across-track.
Predictions of the aboveground biomass density (AGBD; in Mg/ha) and estimates of the uncertainty within each sampled geolocated laser footprint.
A BRDF and sunglint-corrected image of the Atchafalaya basin.
AVIRIS-NG Bidirectional Reflectance Distribution Function (BRDF) and sunglint-corrected surface spectral reflectance images over the Mississippi River Delta. V2 contains corrected files with missing data.
Ratios of (a) maximum rate of carboxylation to respiration at 25 degrees C from Griffin et al. (2022) (Vcmax /R25 ) and (b) maximum electron transport rate to respiration at 25 degrees C from Griffin et al. (2022) (Jmax /R25 ) of white spruce from high and low canopy positions at the Forest Tundra Ecotone (FTE, blue), Alaska, and Black Rock Forest (BRF, green), New York. Boxplots show the median and first and third quartiles. Whiskers display the range of groups with individual points representing outliers falling outside 1.5 times the interquartile range. Different letters represent significant differences between locations and canopy positions.
Measurements of gas exchange, leaf traits, leaf pigments, the photochemical reflectance index, and average photosynthetic photon flux density from hemispherical photographs.
Field sites for ground measurements of solar-induced fluorescence with examples of FluoSpec2 systems.
Half-hourly ground SIF and vegetation indices including NDVI, EVI, red edge chlorophyll index, green chlorophyll index, and photochemical reflectance index at seven crop sites in Nebraska and Illinois.
Forest disturbance intensity 1986 - 2015. This time-integrated map represents the percentage of basal area removal (PBAR) value, regardless of the disturbance year, for pixel locations where only one disturbance event was detected. The maximum PBAR is shown for locations that were disturbed multiple times.
Estimates of forest disturbance intensity for the conterminous United States from 1986 to 2015.
