Forest disturbance intensity 1986 - 2015. This time-integrated map represents the percentage of basal area removal (PBAR) value, regardless of the disturbance year, for pixel locations where only one disturbance event was detected. The maximum PBAR is shown for locations that were disturbed multiple times.
Estimates of forest disturbance intensity for the conterminous United States from 1986 to 2015.
Hillslope transects at three sites showing redistribution of soil organic carbon (SOC) simulated over 160 years in Iowa. Sites (columns): Hoffman, Stinson, and Willis. Upper row shows hillshade maps illustrating topography at each site. Red lines show location of transects proceeding from upslope to downslope (e.g., A to A'). Lower three rows illustrate pattern of SOC along the transect distance (L) at soil depths at beginning of simulation (0 y), after 40 y, and at end of simulation (160 y). Red lines indicate the initial surface elevation at beginning of simulation. Insets highlight cases where soil with low SOC blankets soil with higher SOC.
Model predictions of soil erosion and soil organic carbon redistribution caused by agricultural practices such as tillage erosion.
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.
Estimates of biogenic CO2 flux components from the Solar-Induced Fluorescence for Modeling Urban biogenic Fluxes (SMUrF) model.
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.
Estimates of soil organic carbon (SOC) in tidal wetlands for the northeastern United States.
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.
Total annual methane emissions in 2019 from dairy farms in California. These values represent the sum of emissions from enteric fermentation and manure management practices. Units are Gg per square kilometer per year. Source: total_CH4_CA_2019.tif
