A new tutorial, available on our Resources page, demonstrates how to get ABoVE airborne data sampled at a specific field site.

Soil Moisture Datasets Become Fertile Ground for Applications

An update on the ORNL DAAC's Soil Moisture Visualizer (SMV) is featured in AGU's Eos, Earth & Space Science News.

Timeline for 2018 Daymet Update

Average daily temperature maximum, 2017

Daymet average daily temperature maximum for 2017.

Given the partial government shutdown, the annual update of Daymet may be delayed.

Year-round Soil CO2 Measurements in Alaska

Sites of forced diffusion chamber deployment

Forced diffusion chambers were established at the seven sites along a south-to-north transect from near Fairbanks to Toolik Lake, Alaska.

Soil surface CO2 efflux in Alaska is available from the ABoVE field campaign.

Vegetation Changes Along Alaskan Rivers

Yukon River riverbank erosion and vegetation colonization

Riverbank erosion and vegetation colonization at the Yukon River 1 study area, located along the Middle Yukon River between Circle and Fort Yukon, Alaska, from 1985-2017.

Research from NASA's ABoVE campaign provides a record of riverbank erosion and vegetation colonization along major Alaskan rivers from 1984 to 2017.

Gabon Forest Height Profiles by TomoSAR

Bright areas in the figure on the right illustrates radar scattering through the forest canopy.

Tomographic image of Lope National Park for the cross-section marked by the blue line. Note the contrast between dark areas dominated by surface scattering and the bright areas with scattering through the forest canopy.

Three-dimensional maps of forest structure in Gabon are now available from the 2016 AfriSAR campaign.

Highlights from the Literature

Northern Borneo soil carbon density

Map of predicted soil carbon density (SCD) over the study area in northern Borneo. Reproduced from Labriere et al. (2016).

ORNL DAAC data products were cited in over 300 peer-reviewed articles in 2018. Read about how these data are used in research.

Tracking Rain-On-Snow Events Across Alaska

Alaska rain-on-snow frequency and distribution

Annual time series of days with rain-on-snow summed for each 6-km pixel in Alaska.

Researchers with NASA's ABoVE campaign mapped rain-on-snow events across Alaska from 2003 to 2016.

Climate and Productivity of Arctic Tundra

Arctic tudra MaxNDVI biweekly mean

Arctic biweekly NDVI (green bars) and trend (grey bars) for full tundra for 1999-2015. Biweekly trends statistically significant at the 95% level or greater are marked with an asterisk on the x-axis. From Figure 9 (c) Bhatt et al. (2017) (see dataset documentation).

NASA's ABoVE provides standardized data on potential climate drivers for productivity of Arctic tundra vegetation.

Forest Inventories from Acre, Brazil
