Aboveground biomass (Mg/ha) at 30-m resolution for the tri-state region of Maryland, Pennsylvania, and Delaware in 2011.
LiDAR-derived aboveground biomass, canopy height, and canopy coverage estimates for Maryland, Delaware, and Pennsylvania are now available.
Surface thaw map for Alaska and Northwest Canada on April 25, 2003, derived from the Advanced Microwave Scanning Radiometer (AMSR-E).
A new dataset from NASA's CARVE mission provides the daily thaw state of the Alaskan land surface from 2003 - 2015.

A new dataset from NASA's ABoVE campaign estimates effects of climate on Dall sheep populations throughout Alaska and northwestern Canada.
Spatial patterns of total inorganic nitrogen deposition in the early 1990s. Darker areas have higher levels of nitrogen deposition (mg N/m2/y).
Gridded estimates of atmospheric nitrogen deposition are some of the most downloaded data of 2018.
This image shows the height of the forest canopy for a portion of the Pongara National Park along the Gabon Estuary in Gabon, West Africa. This area includes some of the tallest mangrove forests in the world, indicated by a dark green color, where trees tower up to 60 meters (200 feet). The data were estimated by fusion of PolInSAR and LiDAR data collected by the AfriSAR campaign in March 2016.
NASA’s AfriSAR campaign measured forest structure in Gabon, West Africa to inform estimates of forest carbon storage capacity.

Tree data, canopy cover, and vertical profile metrics from forests in Gabon have been published.
Column-average CO2 measured during the first 20 minutes of flight off the coast of New Jersey on July 11, 2016, for the ACT-America mission.
A new dataset provides remotely-sensed column-average carbon dioxide concentrations measured over the Eastern US.
Long-term maximum NDVI for the ABoVE study area covering the years 2002-2017.
Annual maximum NDVI estimates from 2002-2017 are available for most of Alaska and the Yukon Territory.
MODIS Multi-angle Implementation of Atmospheric Correction (MAIAC) product MCD19A3 is available for order from the Global Subset Tool and the REST API. MCD19A3 is 8-Day 1km Level 3 product and provides Bidirectional Reflectance Distribution Function (BRDF) model parameters and surface albedo.
Measurement stations in the Boston area including two urban sites: Boston University (BU) and Copley Square (COP), and three boundary sites: Harvard Forest (HF), Canaan (CA), and Martha's Vineyard (MVY). Blue shading represents 2014 average afternoon CO2 emissions. See the dataset user guide for more details.
A new dataset from the North American Carbon Program provides atmospheric measurements of CO2 and model estimates of urban emissions at sites near Boston, Massachusetts, USA.
