Predicted soil organic carbon (SOC) content of wetlands at 0-5 cm depth in the vicinity of Cape Cod, Massachusetts, U.S. Estimates represent the period 1998-2018 and were derived from publicly available data sources using a quantile regression forest model. 

Spatial distribution of (a) GPP (gC m2/d) and (b) GPP uncertainty (gC m2/d) across CONUS at 250-m resolution for 10 July 2020

CAM-chem simulated concentrations of ozone (O3) and carbon monoxide (CO) along ATom flight tracks.

Snapshots from select NASA field and airborne campaigns.

The flux site distribution in syntheses focused on compiling fluxes from high latitudes (McGuire et al. 2012, Belshe et al. 2013, Natali et al. 2019, Virkkala et al. 2021 and this study (ABCflux)). The Arctic-Boreal Zone is highlighted in dark grey; countries are shown in the background. Based on the unique latitude-longitude coordinate combinations in the tundra, there were 136 tundra sites in ABCflux, 104 tundra sites in Virkkala et al. 2021, 68 tundra sites in Natali et al., 2019, 34 tundra sites in Belshe et al. 2013, and 66 tundra sites in McGuire et al., 2012. Observations that were included in previous studies but not in ABCflux represent fluxes aggregated over seasonal, not monthly periods.

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.
