Topsoil & Agricultural Economic Losses

Map of study area for dataset.

Study area in the Midwestern US with study site locations and extent of analysis. The study area was limited to the spatial extent of LiDAR topographic data (gray hillshade). Squares represent the 28 sites, a total of 210 km2, that were selected for having plowed, bare soil.

A soil organic carbon index and remote sensing data were used to estimate erosion in Midwestern USA.

Boreal Forest Burned and Unburned Site Comparisons

A typical burned plot in the Saskatchewan, Canada, boreal forest study area.

Fire history and field measurements were used to estimate above- and belowground carbon values.

Atmospheric Concentrations of Halocarbons and Hydrocarbons

Map showing CFC-11 mixing ratio

Mixing ratio of CFC-11 measured by Whole Air Sampler (WAS) during ATom-4 flights in April-May 2018.

The UC-Irvine Whole Air Sampler (WAS) instrument was used during the Atmospheric Tomography (ATom) mission.

Carbon Fluxes From US Coastal Wetlands

Estimated CO2e fluxes and confidence interval ranges for the Mississippi River outlet in Louisiana, United States. This area contains palustrine and estuarine wetlands, and includes stable wetlands, wetland gains and loss events from 2006 to 2011. A: Total flux from 2006 to 2011. B. Uncertainty, as represented by confidence interval range (0.975 - 0.025 quantile distributions of the results of the Monte Carlo Analysis). C-E. The relative contributions of soil, biomass, and methane to the total flux (A).

A new dataset provides maps of surface elevation, land cover, biomass, and estimated coastal wetland carbon fluxes.

Mapping Methane Emissions Across California

Map of California's methane emissions.

Vista-CA provides locations of methane (CH4) emitting facilities and infrastructure in the State of California. In this figure, the distribution of digesters, feed lots, and dairies across the San Francisco Bay Area and Central Valley are shown.

The Vista-CA dataset provides locations of potential methane (CH4) emitting facilities and infrastructure across the state of California.
