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)
Global terrestrial model outputs predicted by the Simple Biosphere Model, Version 4.2 (SiB4), at a 0.5-degree spatial resolution, 2000-2018.
An area of the Mississippi River Delta (Terrebonne and St. Mary Parishes, LA, USA) showing the largest present-day amount of tidal vegetation biomass in the conterminous US. (Source Louisiana_biomass_2015.tif).
Aboveground tidal marsh biomass estimates for six estuarine regions of the conterminous United States.
Examples of spatial patterns of reconstructed SIF at 4 km resolution. Only pixels with a fraction of the specific vegetation type larger than 0.1 are shown. For Total SIF, only pixels with a fraction of corn, soybean, grass/pasture, and forest larger than 0.8 are displayed.
Estimated solar-induced chlorophyll fluorescence (SIF) of specific vegetation types and total SIF available at 4-km resolution.
Riverine N2O emission estimates from headwater streams (a, c, and e) and high-order rivers (b, d, and f) for the 1900s, 1960s, and 2000s. The right panel shows the latitudinal distribution of riverine N2O emissions with the uncertainty range as the standard deviation (shaded areas).
Modeled estimates of annual NO2 emissions for two sets of global rivers and streams covering years 1900-2016 available.
