CO2 Flux for the Northern Gulf of Mexico

pCO2 for the northern Gulf of Mexico.

Monthly composite images of satellite-derived pCO2 for the northern Gulf of Mexico, corresponding to each of the cruises for which observational data were acquired. Black pixels in the images correspond to areas that were masked (e.g., land, clouds), and the dotted lines represent the 45 and 200 m isobaths.

Monthly estimates of ocean surface pCO2 and air-sea flux of CO2 are available from NASA's Carbon Monitoring System.

Active Layer Thickness Across Northern Alaska

Active layer thickness.

Active layer thickness product (ALT) at 30 m resolution near Barrow (Utqiagvik), Alaska.

New data from NASA's Arctic-Boreal Vulnerability Experiment (ABoVE) provide estimates of active layer thickness from airborne radar.

Soil Temperature Profiles for Interior Alaska

USArray measurement sites

USArray measurement sites in Alaska. Sites are labeled with site ID and maximum measurement depth and color-coded by mean annual ground temperature (MAGT in degrees C) of the deepest sensor measurements. Data are omitted for sites disrupted by bears.

Soil temperature data were collected at Alaskan USArray seismic monitoring sites from 2016-2018.

Aerosol Data from the ATom Mission

The ATom aircraft

The ATom aircraft prepares to depart from Punta Arenas in southern Chile on October 14, 2017. During ATom-3, the science team flew over Antarctica and below the ozone hole before continuing on their journey north over the Atlantic Ocean to Greenland and returning to California.

Data collected by the Aerosol Microphysical Properties (AMP) instrument during the Atmospheric Tomography (ATom) Mission is now available.

Monthly Hydrological Fluxes for ABoVE Domain

Average annual precipitation.

Average annual precipitation for 1979-2010 at 0.25 degree resolution across the Arctic Boreal Vulnerability Experiment study domain.

Estimated historical water balance climatologies are available for the Arctic-Boreal Vulnerability Experiment (ABoVE) study domain.

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.
