The Atmospheric Carbon and Transport America (ACT-America) project is conducting airborne campaigns across three regions in the eastern United States to study the transport of atmospheric carbon.

Body

NASA's ACT-America mission measured atmospheric CO2, CO, CH4, and O3 concentrations across the Eastern USA in 2016.

Date of Burning (DoB) was estimated for areas within each fire scar across Alaska and Canada. In this figure, red areas are fire scar locations across central Canada in 2015.

Body

New data from NASA's ABoVE project provide maps of the date of burning within fire scars across Alaska and Canada from 2001-2015.

Typical plot photo for ground cover estimates and location of LAI measurements. A rangepole with GPS and a camera boom was positioned at 2-meter intervals along plot transects. This photo is from the Hollister, Sagebrush01 plot, and the Sagebrush01_5_4 sampling point.

Body

New field data describes vegetation in southern Idaho in order to validate remotely-sensed data in the region.

Domain of the South Atlantic Bight and Gulf of Mexico (SABGOM) model showing water depth (m). For analysis, the Gulf was divided into five subregions used in this study, which are Mexico Shelf (MX), Western Gulf of Mexico Shelf (WGoM), Northern Gulf of Mexico Shelf (NGoM), West Florida Shelf (WF), and open ocean. Arrows indicate the Loop Current (figure from Xue et al., 2016).

Body

Output from the South Atlantic Bight and Gulf of Mexico (SABGOM) model provides insight into biogeochemical cycling and three-dimensional ocean circulation in a gulf-wide context.

Digital elevation model and LiDAR tile boundaries for the area encompassing the Reynolds Creek Experimental Watershed in southwestern Idaho.

Body

LiDAR data collected over southern Idaho was used to derive a high resolution digital elevation model and map of vegetation height across a strong regional climate gradient.
