Tropospheric Aerosol Radiative Forcing Observational eXperiment (TARFOX) - Scanning Mobility Particle Sizer from Wallops ground station
TARFOX_WALLOPS_SMPS is the Tropospheric Aerosol Radiative Forcing Observational eXperiment (TARFOX) Scanning Mobility Particle Sizer (SMPS) data set from Wallops ground station. The TARFOX Intensive Field Campaign was conducted July 10-31, 1996. It included coordinated measurements from four satellites (GOES-8, NOAA-14, ERS-2, LANDSAT), four aircraft (ER-2, C-130, C-131A, and a modified Cessna), land sites, and ships. A variety of aerosol conditions was sampled, ranging from relatively clean behind frontal passages to moderately polluted with aerosol optical depths exceeding 0.5 at mid-visible wavelengths. Gradients of aerosol optical thickness were sampled to aid in isolating aerosol effects from other radiative effects and to more tightly constrain closure tests, including those of satellite retrievals. Early results from TARFOX include demonstration of the unexpected importance of carbonaceous compounds and water condensed on aerosol in the US mid-Atlantic haze plume, chemical apportionment of the aerosol optical depth, measurements of the downward component of aerosol radiative forcing, and agreement between forcing measurements and calculations.
ATom: Light-Absorbing Metallic Aerosols, Single Particle Soot Photometer, 2016-2018
This dataset provides mass mixing ratios and number density of light-absorbing metallic aerosols (LAM) in the size range 180-1290 nm obtained with the NOAA Single Particle Soot Photometer (SP2) during the four deployments of the NASA Atmospheric Tomography (ATom) airborne mission from 2016-2018. The NOAA SP2 detects light absorbing aerosols, such as black carbon (BC), via laser-induced incandescence to provide real-time in situ quantification of refractory aerosol mass and number density. The percent of LAM aerosols attributed to anthropogenic iron oxides (FeOx) by mass is also provided.

CAMEX-3 CLOUD AND AEROSOL PARTICLE CHARACTERIZATION VIDEO V1
CAPAC is a series of three instruments: the Forward Scattering Spectrometer Probe model 300 (FSSP-300), the Two Dimensional Optical Array Probes [Cloud and Precipitation Probes (2D-P)] and the CAPAC video. These instruments flew during CAMEX-3 upon the NASA DC-8 mounted on the left wing. Cloud and aerosol particles were exposed to laser light to measure particle size from 0.3 micrometer to 6.4 millimeter, and both size and shape between 40 micrometer and 6.4 millimeter particle diameter as function of particle size. The size distributions thus determined were integrated to yield particle surface area, and ice and liquid water contents in clouds and precipitation. CAPAC videos are a visual record of the particles and hydrometeors passing through the instrument housing. The purpose of the CAMEX-3 mission was to study hurricanes over land and ocean in the U.S. Gulf of America, Caribbean, and Western Atlantic Ocean in coordination with multiple aircraft and research-quality radar, lightning, radiosonde and rain gauge sites.
