Black Carbon Aerosols from ATom

The SP2 instrument.

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.

Correction to Daymet Monthly Climate Summaries

Daymet precipitation in January 2000

Daymet V3 total precipitation for January 2000 for a subset of the Daymet domain in eastern North America.

The ORNL DAAC has released a correction to “Daymet Monthly Climate Summaries on a 1-km Grid for North America, Version 3."

MODIS MAIAC at ABoVE Flux Towers

ABoVE domain.

New MAIAC data were calculated at 62 flux tower sites within the ABoVE domain in Alaska and Canada.

MODIS Multi-Angle Implementation of Atmospheric Correction algorithm (MAIAC) surface reflectances are available for 62 flux tower sites in the ABoVE domain.

Data collected by the Diode Laser Hygrometer (DLH) instrument during the Atmospheric Tomography (ATom) Mission is now available.

River Ice Breakup and Freeze-up Stages from ABoVE

Freeze-up stages.

Examples of freeze-up stages in the Grayling study area. Landsat images are displayed as color composites (R: SWIR, G: NIR, B: green), where water appears dark blue and snow/ice appears light blue.

Estimates of river ice breakup and freeze-up stages along selected reaches of the Yukon and Tanana Rivers in the Yukon River Basin in interior Alaska from 1972-2016 are now available from ABoVE.
