30 m resolution maps of aboveground biomass density (AGBD) over the New England region in 2015. a) The mean of the posterior distribution sampled from a Markov chain Monte Carlo (MCMC) model. b) The AGBD estimate over an entire pixel adjusted by canopy cover (i.e., AGBD multiplied by canopy cover percentage). Source: Tang et al., 2021

Body
This dataset provides 30 m gridded estimates of aboveground biomass density (AGBD), forest canopy height, and tree canopy coverage for the New England Region of the USA for 2015.

Globally the tallest mangrove forests in coastal Gabon are estimated up to 63 m. The photo insets show locations where individual trees were measured in situ up to 65 m tall (Simard et al., 2019).

Body
An update to a dataset that characterizes the global distribution, biomass, and canopy height of mangrove-forested wetlands based on remotely sensed and field measurements.

Image Media
Caption

Estimated total ecosystem carbon for the northeast region of the U.S. for the years 1990 (left) and 2010 (right). The estimates were produced from an inventory-constrained version of the Carnegie-Ames-Stanford Approach (CASA) carbon cycle process model.

Body
This dataset provides estimates of forest carbon stocks and fluxes as a function of the number of years since the most recent disturbance for decadal benchmark years.

Caption

Examples of spatial patterns of reconstructed SIF at 4 km resolution. Only pixels with a fraction of the specific vegetation type larger than 0.1 are shown. For Total SIF, only pixels with a fraction of corn, soybean, grass/pasture, and forest larger than 0.8 are displayed.

Body
Estimated solar-induced chlorophyll fluorescence (SIF) of specific vegetation types and total SIF available at 4-km resolution.
