Carbon Emissions from Transportation

DARTE provides annual estimates of on-road CO2 emissions

Map of DARTE on-road CO2 emissions for the conterminous United States for the year 2017.

The updated DARTE dataset provides high-resolution, annual, on-road CO2 emissions for the conterminous United States.

Winter Carbon Flux From Arctic & Boreal Soils

Soil CO2 flux estimates.

Mean daily soil CO2 flux in each month of the non-growing season (NGS) during the baseline period (2003-2018). Gridded estimates are provided at 25-km resolution for the pan-Arctic and Boreal permafrost region.

New data from the Arctic-Boreal Vulnerability Experiment (ABoVE) provide winter soil CO2 flux estimates for the pan-Arctic and Boreal regions.

Planetary Boundary Layer Heights for Eastern USA

Estimates of the height of the planetary boundary layer (PBL) are available from the Atmospheric Carbon and Transport - America (ACT-America) airborne campaign.

Forest Carbon Stocks and Fluxes for Southeastern US

Data examples.

Maps of the number of years since the most recent disturbance, aboveground biomass, and net ecosystem productivity in the year 2010, for forests of the Southeastern USA.

A new Carbon Monitoring System dataset used a carbon cycle process model and historic data to estimate aboveground woody biomass and net ecosystem productivity over time.

Vegetation and Carbon Impacts of Boreal Wildfires

A new dataset completes four years of post-fire vegetation sampling at burned sites in Canada's Northwest Territories.

Webinar: Publication-Quality NetCDF Data

Webinar: NetCDF Why and How

The webinar describes step-by-step methods, software, and tools that can be used to create, visualize, and standardize netCDF files.

The tutorial code and recording from our NASA Earthdata webinar "NetCDF Why and How: Creating Publication Quality NetCDF Datasets" is now available.

Global Solar-Induced Chlorophyll Fluorescence (SIF)

Solar-induced chlorophyll fluorescence.

Predicted spatially contiguous solar-induced chlorophyll fluorescence (SIF) across the United States for August 1 - 16, 2015. Areas of high SIF are in red, and areas of low SIF are in blue. Agricultural areas, like the U.S. Midwestern corn belt, often have a high rate of photosynthetic production which results in high SIF.

High-resolution, global, estimates of SIF based on data from the OCO-2 satellite serve as a proxy for rates of terrestrial photosynthesis.

PhenoCam Data Updated

PhenoCam Sites.

Spatial distribution of PhenoCam data across ecological regions of North America. Background map illustrates USA Environmental Protection Agency Level I Ecoregions. Data counts have been aggregated to a spatial resolution of 4°, and the size of each circle corresponds to the number of years of data.

A new version of the PhenoCam vegetation phenology data products is now available.

Snow and Thaw Depth Near Fairbanks, AK

Farmer's Loop Transect 2.

Active layer thaw depth was recorded each year during the late summer from 2014 - 2018 at sites including the Farmer's Loop Transect 2 near Fairbanks. (Image Credit: Tom Douglas)

Two new datasets provide soil active layer thaw depth and end-of-season snow depth at sites near Fairbanks, Alaska.

High Resolution Tree Canopy Cover for MD and DE

Pittsburgh Tree Canopy Cover.

Estimated tree canopy cover (in green) near Pittsburgh, Pennsylvania, for the year 2008.

Statewide tree canopy cover at 1m resolution is now available for Maryland and Delaware.
