One-second resolution measurements of refractory black carbon mass concentration collected during NASA's Atmospheric Tomography (ATom) airborne mission. Data is gathered using the NOAA Single Particle Soot Photometer, a laser-induced incandescence instrument for measuring black carbon in individual particles. The dataset is managed by ORNL_CLOUD and appears on multiple government data platforms.
Hydrographic profile data containing chemical, physical, and optical measurements from cruise SJ0609 in the tropical North Atlantic and Caribbean Sea.

It is hosted on multiple government data platforms, indicating its established use.
High-resolution plasma data from the Voyager 1 spacecraft's Plasma Spectrometer instrument. The National Aeronautics and Space Administration produced this dataset by fitting convected isotropic Maxwellian distributions to the raw measurements. Sampling times range from 12 to 192 seconds, with more frequent sampling early in the mission.
Four oceanographic expeditions from 2009 to 2011 collected coincident profiles of primary productivity and downwelling irradiance spectra at stations within 15-23° N and 105-121° E. The dataset includes vertical profiles of downwelling irradiance (Ed(λ,z)) at 1 nm intervals from 350-700 nm, averaged from three replicates taken near local noon. Derived parameters include Usable Solar Radiation (USR(z), 400-560 nm) and Photosynthetically Active Radiation (PAR(z), 400-700 nm) integrated from the spectral data.
The Ultraviolet Imager (UVI) is a small camera that detected and produced images of the ultraviolet light of the aurora, day and night. Key Parameter images are calculated at nominal 5-10 minute intervals at spacecraft altitudes above 6 Earth radii, forming a rectangular two-dimensional array of 228 rows by 200 columns. This dataset is produced by the National Aeronautics and Space Administration and was last updated in March 2026.
Voyager 2 high-resolution plasma data contains density, thermal speed, and velocity components in RTN coordinates. The data was produced by NASA by fitting a convected isotropic Maxwellian distribution to spectrometer readings. Sampling times range from 12 to 192 seconds, with more frequent sampling early in the mission.
