(A) A Soil Respiration Station (SRS), (B) a SRS data logger, and (C) a Forced Diffusion Chamber (FD chamber) deployed at a boreal forest site in central Alaska.
Data collected by soil respiration stations installed at boreal and tundra sites are available from the Arctic-Boreal Vulnerability Experiment (ABoVE).
Biomass (Mg ha-1) for the northern Minnesota site.
Six Landsat focus sites were used to produce disturbance history and forest biomass maps.
Map of study area communities. GMUs are Game Management Units and GMU21D is highlighted.
Environmental conditions during moose hunting season for 2000-2016 are available for rural Alaska.
Yaxing Wei has been named Lead Scientist of the ORNL DAAC.
Geospatial information scientist, Dr. Yaxing Wei, is the new ORNL DAAC Lead Scientist.
Examples of fractional cover distribution in a tundra region near Lake Narvakrak in the Noatak River National Preserve: (a) very high-resolution imagery from Google Earth; (b) fractional cover of woody component; (b) fractional cover of herbaceous component; (d) fractional cover of nonvascular component.
Maps of three major wildland fire fuel types are available from the Arctic-Boreal Vulnerability Experiment.
Mean snowmelt Day of Year (DOY) for the years 2001-2018 for North America. The DOY values for snowmelt timing were identified by observing the transition from snow-cover to no-snow for individual MODIS pixels throughout the annual melt period.
The second version of snowmelt timing maps for North America is available for the period 2001 through 2018.
Arctic-CAP flights consisted of vertical profile maneuvers from near the surface to 6 km altitude around the ABoVE domain each month. Profiles were flown at each of the 25 locations listed across the top of this figure.
Atmospheric gas concentrations collected during the Arctic Carbon Aircraft Profile (Arctic-CAP) campaigns are now available.
Daily mean shortwave blue sky albedo for February 28, 2000. Blue sky refers to albedo calculated under real-world conditions with a combination of both diffuse and direct lighting based on atmospheric and view-geometry conditions.
Daily “blue sky” shortwave albedo data were derived from the MODIS bi-directional reflectance distribution function.
Dry-air mole fraction of methyl bromide measured in Programmable Flask Package samples taken during Atom-2 flights in January-February 2017.
Two new instrument datasets available from the Atmospheric Tomography Mission (ATom).
The UWG meets once per year to review the status of ORNL DAAC operations and to provide recommendations.
Joe Sexton, Michael Dietze, Nancy Glenn, and Lucy Hutyra will be rotating off the User Working Group this year.
