30-year annual average maximum temperature for Alaska at 60-m resolution for (a) the last glacial maximum period ~18,000 years ago and (b) the modern period 1975-2005.
A new dataset provides 30-year climate 'normals' for the last glacial maximum (~18,000 years ago) and the present day in Alaska.

The NOAA Single Particle Soot Photometer (SP2) is a laser-induced incandescence instrument primarily used for measuring the black carbon mass content of individual particles.
Black carbon concentrations were measured over remote regions of the Earth during NASA's Atmospheric Tomography (ATom) Mission.

Daymet daily surface weather and climatological summaries have been cited in nearly 300 peer-reviewed articles. Read about how this popular data product is used in research.
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.
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.
