Ecosystem Functional Types Across the USA

Ecosystem functional type (EFT) categories

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

New data from the Carbon Monitoring System classifies ecosystems based on their similar ecosystem functioning.

ABoVE Data Measure Arctic Greening

MODIS and CCaN average growing season

MODIS (left) and CCaN (right) average growing season NDVI.

A new study of long-term NDVI trends across the North Slope of Alaska presents high-resolution growing-season NDVI from MODIS.

Field Measurements After Alaskan Wildfires

Forest plots in Tanana, AK

Photos from July 2017 field surveys near Tanana, Alaska, from left to right: unburned forest site; burned forest near the Spicer Creek Fire; high burn severity forest site.

Researchers with NASA's ABoVE field campaign measured burn severity in spruce forests that burned in 2015 near Tanana, Alaska.

Soil Carbon Stocks for Tidal Wetlands

Three carbon stock estimation approaches for the Louisiana Delta region

Results of three carbon stock estimation approaches for the Louisiana Delta region: Left, using independently generated soil carbon maps from SSURGO; Middle, using the SSURGO bias-corrected for bulk density; Right, using single average carbon stock value from the compiled soil core data.

Soil carbon stocks for tidal wetland areas of the United States were estimated using four modeling approaches.

Atmospheric Profiles of Hydroxyl and Formaldehyde

Full flight tracks for ATom missions 1

Circles mark the locations of the 139 selected profiles sampling the remote troposphere. Circle color indicates HCHO column densities integrated over each ATom profile. Data are overlain on global gridded OMI HCHO column densities averaged over the mission. From Wolfe et al. (2019) (see dataset references).

New data from NASA's Atmospheric Tomography Mission (ATom) provide hydroxyl and formaldehyde column density in the remote troposphere.
