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.

Chambers used to measure diffusive CH4 fluxes. a) Large chamber resting on the pre-installed aluminum collar, sealed on edges with pipe insulation. b) Five-gallon (18.9-liter) bucket with an open bottom and air-tight screw lid to measure hotspot flux locations.

Figure 1. (a) Aerosol extinction calculated using Mie theory from composition-resolved size distributions plotted as a function of measured extinction from the SOAP cavity ring-down spectrometer during the ATom-4 campaign, showing representative error bars. (b) Calculated aerosol absorption and measured absorption from the SOAP photoacoustic spectrometer for cases when absorption >2 *10-6 m-1 (2x the detection limit).
Mean global soil respiration derived from Version 5 of the Soil Respiration Database (SRDB-V5).
The sums of seasonal mean SMUrF-based NEE and ODIAC-based FFCO2 for CONUS (a), western Europe (b), and East Asia (c) for 2018 in centered panels. City-wide GEE, Reco, NEE, and FFCO2 over JJA 2018 are provided around the centered panels.
Carbon dioxide concentrations at the MUR site in Salt Lake City, Utah, show a pronounced seasonal pattern of higher CO2 in the winter months.
