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.

Body
16 years of carbon pools and fluxes estimated from CARDAMOM for the contiguous USA at 0.5-degree resolution recently published.

Daily-corrected SIF at 740 nm for August 2015. The highest SIF values during this time period were observed in agricultural sectors in the Northern Hemisphere.

Body
This dataset provides monthly global solar-induced chlorophyll fluorescence (SIF) estimates from fused SCIAMACHY and GOME-2 at a 0.05-degree resolution from August 2002 through December 2018.

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.

Descriptive statistics for snow melt duration (SMD) for the period 1988-2016, including mean, standard deviation, and coefficient of variation. Units are the number of days per year. 

Body
This dataset provides the annual period of snowpack melting across northwest Canada; Alaska, U.S.; and parts of far eastern Russia at 6.25 km resolution for the period 1988-2016.
