This overview map shows thirty unique vegetation canopy structure classes identified within the Great Smoky Mountain National Park in Tennessee and North Carolina, USA.
This revised dataset characterizes canopy structure based on LiDAR surveys of the Great Smoky Mountains National Park.

NASA's AfriSAR campaign provides critical data on canopy height and structure of tropical forests in Gabon, West Africa.
Station-level cross validation of Daymet at weather station locations showing annual mean absolute error (MAE; degrees C) for the variable maximum temperature (tmax) in 2016.
Daymet provides information to access the accuracy and uncertainty of modeled climate data at each ground station location or two-degree tile.
VIIRS/S-NPP true color reflectance image (Red = Band I1, Green = Band M4, Blue = Band M3) from May 7, 2018, visualized in NASA's WorldView.
VIIRS land products are now available for visualization and download from ORNL DAAC's MODIS subsetting tools suite.
ACT-America combines ground-based, airborne, and satellite observations of greenhouse gases.
Measurements of CO2, CO, and CH4 concentrations at tower sites have been updated to include years 2015 - 2017.
ACT-America is a NASA Earth Venture Suborbital-2 mission to study the transport and fluxes of atmospheric carbon dioxide and methane across three regions in the eastern United States.
Merged airborne atmospheric gas and navigational data from the Summer 2016 and Winter 2017 campaigns are now available.
MODIS Land Cover MCD12Q1 inventory was updated from Collection 5 to Collection 6. New MODIS Global Subsets Tool orders will now receive the updated land cover classification product from year 2016 instead of year 2013. The MODIS Fixed Sites Tool was also updated with the new land cover data.
Two VIIRS products - VNP09H1 (surface reflectance) and VNP15A2H (leaf area index/fraction of photosynthetically active radiation) - are now available via the Global Subsets Tool.
MODIS/Terra Net Evapotranspiration data product MOD16A2 is now available via the Fixed Sites Subsets Tool. The tool provides customized subsets and visualizations of several MODIS Collection 6 land products for selected field and flux tower sites around the world.
