Overview of the assimilation system (CLM5-DART) that combines observations with model ensemble simulations from CLM5.0. Satellite-derived observations of aboveground biomass and leaf area index were used to adjust the simulated model state of CLM5.0. Source: Razcka et al. (2021)
Monthly estimates of biomass stocks and land-atmosphere carbon exchange across the western United States available.
ABGB outputs over CONUS derived from CARDAMOM vs. the CMS project-funded ABGB estimated from inventory and satellite data (Yu et al., 2021). The left panel shows the colormaps of differences between ABGB from CARDAMOM and ABGB from CMS for the years 2005, 2010, and 2015. The right panel is the scatter plot showing the pixel-level ABGB deviations from the 1:1 line for CARDAMOM- and CMS-derived outputs.
16 years of carbon pools and fluxes estimated from CARDAMOM for the contiguous USA at 0.5-degree resolution recently published.
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).

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.
The AVIRIS-NG instrument detected large methane plumes coming from Sunshine Canyon Landfill during its October 2016 overpass. The plumes are shown in a yellow to red gradient, with red representing higher concentrations of methane. Image credit: Cusworth et al. 2020.
NASA's AVIRIS-NG instrument detected multiple massive methane plumes in California and much more.
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.
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.
Overview of the Simple Biosphere Model (SiB4) that estimates carbon fluxes among the atmosphere, vegetation, and soils. Input information is shown in yellow boxes. These datasets include a selection of the output variables (blue boxes). Source: Haynes et al. (2020)
