Daymet 2019 Data Now Available

Map of Daymet Single Pixel Download Locations

The Single Pixel Extraction Tool allows a user to obtain daily Daymet data in a tabular format for a single geographic point (pixel) specified by latitude and longitude.

Daymet gridded estimates of daily weather parameters are now available for the years 1980 to 2019.

Soil Organic Carbon Estimates for Mexico

Map of Mexico's soil organic carbon.

(A) Digital map of soil organic carbon (kg/m2) at 1 m depth and 90 m spatial resolution. The black and blue colored areas are urban areas and water bodies. (B) An area in northern Mexico illustrating the level of detail achieved by mapping across 90 m grids.

Estimates of soil organic carbon are now available from Mexico at a 90 meter resolution.

Explaining Vegetation Greening Trends in Yellowstone

Map of NDVI in Greater Yellowstone Ecosystem

Trends in maximum annual NDVI for natural vegetation within the Greater Yellowstone Ecosystem (GYE) from 1989 to 2014 (Emmett et al. 2019).

Daymet and North American Carbon Program (NACP) data were used to study Normalized Difference Vegetation Index (NDVI) trends across the Greater Yellowstone Ecosystem.

ORNL DAAC Social Media Moving to @NASAEarthData

Logo for NASA Earthdata.

The Earth Science Data and Information System (ESDIS) Project manages the operations of EOSDIS including Distributed Active Archive Centers (DAACs) like the ORNL DAAC.

The ORNL DAAC's social media presence is moving to @NASAEarthData.

Harmonized Global Maps of Biomass

Map of biomass carbon density.

Global maps of above and belowground biomass carbon density: (a) aboveground biomass carbon density, (b) belowground biomass carbon density.

Temporally consistent and harmonized global maps of aboveground and belowground biomass carbon density are now available.

Welcome, New User Working Group Members!

Word art of "Welcome"

The UWG meets once per year to review the status of ORNL DAAC operations and to provide recommendations.

Christine Laney, Isaac Larsen, Alexey Shiklomanov, and Ying Sun have joined the ORNL DAAC User Working Group.

Model-Derived CO2 Biogenic Fluxes

Gross Primary Productivity

Mean gross primary productivity (GPP) for the conterminous US and North America in grams of carbon per unit area per month.

Carbon fluxes and uncertainties are available from the Atmospheric Carbon and Transport - America (ACT-America) project.

Open Water Pixel Masks from ABoVE Flight Paths

AirSWOT Imagery

Example of color-infrared imagery shown alongside the corresponding semi-automated open water classification at Old Crow Flats, Alaska.

AirSWOT imagery from the 2017 Arctic-Boreal Vulnerability Experiment (ABoVE) was used to create water masks across parts of Canada and Alaska.

Burn Severity Index of Canadian Ecoregions

Map of study area.

Study area included sites burned in 2014 and 2015 in the southeastern portion of the Northwest Territories and northern Alberta of Canada. The study area includes all 2014 and 2015 fires within a radius of approximately 300 km from Great Slave Lake.

Pre- and post-fire Landsat images were used to classify burn severity of soil organic matter across portions of arctic Canada.
