Atmospheric Photolytic Rates from ATom

Photolysis frequency (J-value).

An image of photolysis frequency (J-value) for J-O1D under cloudy conditions from the GSFC GMI model.

Atmospheric photolytic rates for ozone and nitrogen dioxide were estimated using nine global chemistry-climate or chemistry-transport models.

Mangrove Forests in River Deltas

Mangrove extent, gain, and loss.

Map of a portion of Peruvian coast showing areas of mangrove extent, gain, and loss from the year 2000 to 2016.

Maps of mangrove forest extent and change is available for river deltas in six countries: Gabon, Jamaica, Mozambique, Peru, Senegal, and Tanzania.

Forest Aboveground Biomass in Para, Brazil

Forest aboveground biomass.

Assimilated predictions of forest aboveground biomass across the Paragominas Municipality, Brazil.

Estimates of forest aboveground biomass for the Paragominas municipality, in Para, Brazil, were derived from LiDAR and PALSAR data.

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.

Temporal Dynamics of Lake Area in the Arctic

Four ABoVE study sites.

Near-daily CubeSat imagery was collected within four large regions across the ABoVE study area. Timeseries of lake area were derived from the CubeSat imagery for more than 80,000 lakes in these regions.

Near-daily CubeSat imagery provides information on the seasonal dynamics of more than 80,000 lakes.

Mapping Global Mangrove Forests

Mangrove cover and height.

Heights of mangrove forests along the northern coast of Borneo (countries Brunei and Malaysia) reach 39 meters tall. Mangrove cover is illustrated in orange, where darker orange represents taller canopies.

Maps of the global distribution and biomass of mangrove forests are available for 116 countries.

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 LP DAAC logo

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.
