Greenhouse Gas Concentrations for Six US Cities

Carbon dioxide concentrations.

Carbon dioxide concentrations at the MUR site in Salt Lake City, Utah, show a pronounced seasonal pattern of higher CO2 in the winter months.

Hourly urban greenhouse gas measurements are available for cities in the CO2 Urban Synthesis and Analysis (CO2-USA) Data Synthesis Network.

Soil Organic Carbon in Tidal Wetlands

Estuary Classes

Estuaries classes used in the study: former river valley primary estuary, former glacier valley primary estuary, river delta primary estuary, tectonic structural primary estuary, coastal lagoon secondary estuary, and unclassified estuary.

Soil organic carbon (SOC) estimates and environmental data for US estuaries are available for the period 1972-2015.

Forest Carbon Across the Western USA

Above ground live tree carbon.

Annual estimates of aboveground live tree carbon (g/m2) as simulated with the Community Land Model (4.5) at 1/24-degree (4 km x 4 km) resolution.

The North American Carbon Program provides new, annual, estimated forest carbon budgets for the Western USA from 1979 to 2099.

CO2 Concentrations in the Boston Area

Map of measurement stations in the Boston network and 2014 average afternoon CO2 emissions.

Measurement stations in the Boston area including two urban sites: Boston University (BU) and Copley Square (COP), and three boundary sites: Harvard Forest (HF), Canaan (CA), and Martha's Vineyard (MVY). Blue shading represents 2014 average afternoon CO2 emissions. See the dataset user guide for more details.

A new dataset from the North American Carbon Program provides atmospheric measurements of CO2 and model estimates of urban emissions at sites near Boston, Massachusetts, USA.

Soil Carbon Content Across the Great Plains

Visualization of Surface Soil Organic Carbon Fractions across the Great Plains Region, USA.

Visualization of surface soil organic carbon fractions across the Great Plains region, USA, using nearest neighbor interpolation (from the ORNL DAAC Spatial Data Access Tool).

A new dataset provides gridded estimates of organic carbon in soil at 1 km resolution across four US states.
