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.

Annual time series of days with rain-on-snow summed for each 6-km pixel in Alaska.
Researchers with NASA's ABoVE campaign mapped rain-on-snow events across Alaska from 2003 to 2016.
Spatial patterns of total inorganic nitrogen deposition in the early 1990s. Darker areas have higher levels of nitrogen deposition (mg N/m2/y).
Gridded estimates of atmospheric nitrogen deposition are some of the most downloaded data of 2018.
