Aboveground Biomass of California Forests

Per-tree AGB (kg) derived from LiDAR

Per-tree aboveground biomass (kg) derived from LiDAR-measured tree heights for the Blacksmith site in 2012.

A new dataset provides LiDAR-derived estimates of aboveground biomass from locations throughout California between 2005 and 2014.

Wildfire Burn Severity Across Alaska and Canada

30-m dNBR for a burn scar in ABoVE grid tile Bh05Bv03

The differenced Normalized Burned Ratio (dNBR) for a burn scar from fires in 2015 within ABoVE grid tile Bh05Bv03. A higher dNBR indicates a higher fire severity.

New data from NASA's ABoVE campaign provides a high-resolution record of differenced Normalized Burned Ratio (dNBR) for fires from 1985-2015.

Canopy Structure in the Great Smoky Mountains

Map showing thirty unique vegetation canopy structure classes in Great Smoky Mountain National Park

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.

Daymet Goodness-of-Fit Statistics for 2017

Daymet station-level cross-validation statistics for year 2016

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.
