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.

Amazonia Forest Canopy Structure from LiDAR

Map of Para, Brazil.

Bounding boxes for LiDAR tiles from surveys over western Para, Brazil, are depicted in Google Earth from the KMZ companion file. Each feature in the KMZ provides key metadata about the corresponding tile.

LiDAR surveys over forest research sites across the Amazon rainforest in Brazil are available.

Volatile Organic Compound Concentrations

Global map showing measurements by TOGA.

Measurements of atmospheric acetone concentration from samples collected by the Trace Organic Gas Analyzer (TOGA) during ATom-3 flights in 2017.

Concentrations of volatile organic compounds (VOCs), measured by the Trace Organic Gas Analyzer (TOGA), are available.

Snowoff Date from 1988-2016

Maps showing snowoff date statistics.

Summary statistics for the snowoff date from 1988-2016 across the study domain: mean (left), standard deviation (middle), and coefficient of variation (right).

Snowoff dates, detected by passive microwave, are available across Alaska, northwestern Canada, and the Russian Far East.

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.
