Tower-based carbon measurements from ACT-America

A map showing locations of ACT-America towers

Map of the locations of ACT-America towers active in 2016.

Data from ACT-America provides atmospheric carbon measurements from nine towers in the Eastern US.

Vegetation Structure in the Great Smoky Mountains

Map shows thirty unique vegetation canopy structure classes identified within the Great Smoky Mountain National Park

This overview map shows thirty unique vegetation canopy structure classes identified within the Great Smoky Mountain National Park in Tennessee and North Carolina, USA.

An updated dataset characterizes vegetation canopy structure in the Great Smoky Mountains National Park.

Fire Weather Indices for Interior Alaska

Fire Weather Index (FWI) for Interior Alaska on July 22, 2006.

Fire Weather Index (FWI) for Interior Alaska on July 22, 2006. FWI is a numerical rating between 0 and 30 where higher values indicate a higher risk of wildfire.

New data from Alaska quantify the daily weather conditions and risk of wildfire from 2001 to 2010.

Methane Emissions in Los Angeles

Locations for infrastructures associated with the energy industry with known or expected potential to emit CH4 in the South Coast Air Basin (SoCAB)

Locations for infrastructures associated with the energy industry with known or expected potential to emit CH4 in the South Coast Air Basin (SoCAB). Vista-LA includes a total of 33,614 features across 13 layers. From Carranza et al., 2017.

A new dataset from Vista-LA provides an inventory of potential methane emitting facilities in the greater Los Angeles urban area.

Mapping wildfires across Alaska and Canada

Date of Burning (DoB) was estimated for areas within each fire scar across Alaska and Canada.

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.

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

ACT-America Tracks Atmospheric Carbon

The ACT-America mission

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.

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

Vegetation in Idaho shrublands

Typical plot photo for ground cover estimates and location of LAI measurements.

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.

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