Long-term Climate Normals for Alaska

Annual Average Maximum Temperature for Alaska

30-year annual average maximum temperature for Alaska at 60-m resolution for (a) the last glacial maximum period ~18,000 years ago and (b) the modern period 1975-2005.

A new dataset provides 30-year climate 'normals' for the last glacial maximum (~18,000 years ago) and the present day in Alaska.

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.

Soil Moisture and Tree Measurements at Harvard Forest

Harvard Forest Canopy

Upward-facing photo of the canopy at Harvard Forest (transect 2, plot 57) on 2012-10-18.

Ground-based data collected at the Harvard Forest site was used to validate Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) soil moisture estimates.

Subsistence Use Areas in Alaska

Subsistence Resource Use Areas

Combined map of subsistence resource use areas of Interior Alaskan communities with (1) points marking harvest effort locations, (2) polygons indicating harvest effort areas, and (3) lines indicating linear harvesting activity.

Maps of the search and harvest areas used by residents of Interior Alaska are available.

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.

Properties of Tropical Aerosols

NASA DC-8 Aircraft.

The NASA DC-8 aircraft was used for the ATom missions.

Aerosol data collected during Atmospheric Tomography Mission (ATom) will inform on new particle formation occurrence in the tropics.

ORNL DAAC Needs Your Feedback!

NASA's Earth Observing System Data and Information System.

NASA's Earth Observing System Data and Information System (EOSDIS) is a key core capability in the Earth Science Data Systems (ESDS) Program.

Solicitations for the 2019 NASA EOSDIS Annual Customer Satisfaction Survey have been distributed by email.

Vegetation Imagery from Toolik Lake, Alaska

Toolik plot photo.

A plot photo (#0656) taken at the largest study area "Toolik" at elevation 765.7 m. The small white object was included in many of the photos as a color reference. The photographer's boots are also often visible, in this photo they are to the lower left of the white object.

A new ABoVE dataset offers hundreds of ground-based vegetation photos which may serve as a reference for studies of climate and vegetation change in the area.

New Data from the Atmospheric Tomography (ATom) Mission

ATom mission logo

The Atmospheric Tomography (ATom) Mission is an Earth Venture Suborbital-2 mission to measure greenhouse gases and human-produced air pollution in remote areas.

Five new datasets from ATom provide measurements of greenhouse gases and human-produced air pollution from 2016 to 2018.
