Thirty+ Year Timeseries of Arctic Land Cover

Land Cover Classes.

Land cover (10-class product) for the year 2014 for ABoVE tile BH03V04. The pixel resolution is 30 m and a tile is 180 x 180 km.

Research from NASA's ABoVE project provides annual land cover classifications from 1984 to 2014 for Alaska and the Canadian Arctic.

Changing Availability of Subsistence Resources in Alaska

This photo from June 2016 shows the "extreme" growth of lake grass in a lake near the Tok Community, Alaska.

ABoVE researchers worked with rural communities to document environmental changes that affect access to subsistence resources.

Ecosystem Functional Types Across Mexico

Ecosystem functional type.

Spatial distribution of 64 ecosystem functional type (EFT) categories across Mexico. For each pixel, the dominant EFT is reported.

New data from the Carbon Monitoring System classifies Mexico's ecosystems based on their ecosystem functioning.

Spectral Reflectance of Tundra Plants

Common Garden Ecotype site.

A plot at a common garden ecotype site near Eagle Creek, Alaska. Common garden sites were established with different populations of the tussock-forming sedge taken from different latitudes in Alaska.

Researchers with the Arctic-Boreal Vulnerability Experiment (ABoVE) measured plot-level and species-specific full-spectrum reflectance data for tundra plants.

Workshop on NASA Data for Ecology

Alison Boyer at the 2019 Ecological Society of America meeting.

ORNL DAAC Chief Scientist Alison Boyer describes one of her favorite publications that demonstrates how data archived at the ORNL DAAC can be used in ecological research.

Materials are available from a recent workshop presented at the 2019 Ecological Society of America meeting.

Sub-Meter Scale Vegetation Maps for Toolik Lake, Alaska

Vegetation communities.

Vegetation communities for the Toolik footprint shown at 1:25,000 scale.

Plant communities near Toolik Lake research station in Alaska were classified at 20 cm resolution based on airborne imagery and lidar surveys.

Black Carbon Aerosols from ATom

The SP2 instrument.

The NOAA Single Particle Soot Photometer (SP2) is a laser-induced incandescence instrument primarily used for measuring the black carbon mass content of individual particles.

Black carbon concentrations were measured over remote regions of the Earth during NASA's Atmospheric Tomography (ATom) Mission.

Correction to Daymet Monthly Climate Summaries

Daymet precipitation in January 2000

Daymet V3 total precipitation for January 2000 for a subset of the Daymet domain in eastern North America.

The ORNL DAAC has released a correction to “Daymet Monthly Climate Summaries on a 1-km Grid for North America, Version 3."

MODIS MAIAC at ABoVE Flux Towers

ABoVE domain.

New MAIAC data were calculated at 62 flux tower sites within the ABoVE domain in Alaska and Canada.

MODIS Multi-Angle Implementation of Atmospheric Correction algorithm (MAIAC) surface reflectances are available for 62 flux tower sites in the ABoVE domain.
