Arctic Whole Air Samples

Graph showing vertical profile maneuvers.

Arctic-CAP flights consisted of vertical profile maneuvers from near the surface to 6 km altitude around the ABoVE domain each month. Profiles were flown at each of the 25 locations listed across the top of this figure.

Atmospheric gas concentrations collected during the Arctic Carbon Aircraft Profile (Arctic-CAP) campaigns are now available.

Reactive Gas and Whole Air Samples from ATom

Map of methyl bromide data collection.

Dry-air mole fraction of methyl bromide measured in Programmable Flask Package samples taken during Atom-2 flights in January-February 2017.

Two new instrument datasets available from the Atmospheric Tomography Mission (ATom).

Historical and Future Leaching from the Mississippi River Basin

Distribution map of mean dissolved inorganic carbon leaching.

Spatial distribution of mean dissolved inorganic carbon (DIC) leaching (g c/m2/yr) in the 2090s estimated by S(ALL) simulation experiment (including future climate, elevated CO2, and land use changes). Climate change scenarios were derived from three climate models named CCSM3 (panels a and b), ECHAM (c and d), and CCCMA (e and f) under high (A2) and low (B1) emission scenarios, respectively.

New data from the Carbon Monitoring System (CMS) offers insights into how environmental factors affect the dynamics of leaching.

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.
