Tropical Forest Biomass in Gabon

Aboveground biomass.

Aboveground biomass mapped at 0.25 ha resolution for the Mondah study site in Gabon, West Africa.

The AfriSAR campaign produced maps of aboveground biomass for four forested sites in Gabon based on field data and LiDAR scans.

Greenhouse Gases from Arctic-CAP

Monitoring carbon dynamics during the 2017 growing season.

Arctic-CAP flight lines (orange) sampled Arctic and boreal regions of Alaska and Canada. Pins mark the locations of vertical profiles that were repeatedly acquired during the 2017 growing season.

Atmospheric carbon and methane concentrations were measured during the 2017 Arctic Carbon Aircraft Profile (Arctic-CAP) flights throughout Alaska and western Canada.

Daymet Data Now Available in AppEEARS

The Land Processes DAAC distributes NASA Earth Observing System data. They developed the AppEEARS tool to provide access to a wide range of data from instruments including MODIS, VIIRS, SMAP, and now Daymet.

Daymet Version 3 daily weather data for North America is now available through the AppEEARS subsetting tool from NASA's Land Processes DAAC.

Monitoring Permafrost with P-Band SAR

Active layer thickness and uncertainty.

Active layer thickness with uncertainty for a flight swath over the northern section of Alaska's Dalton Highway in summer 2015.

NASA's ABoVE airborne campaign provides estimates of active layer thickness and soil properties derived from the AirMOSS instrument.

Mechanistic Soil Nitrogen Module for CMAQ

Soil nitrous oxide emissions.

Soil nitrous oxide emissions on a monthly average basis for July 2011 estimated with the mechanistic scheme.

A new model dataset improves the timing and spatial distribution of estimates of soil nitrogen emissions.
