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.

本数据集提供了由美国国家海洋和大气管理局（NOAA）单颗粒碳烟光度计（SP2）在2016-2018年期间进行的NASA大气层析（ATom）航空任务的四次部署中获取的，针对180-1290纳米尺寸范围内的光吸收金属气溶胶（LAM）的混合比和质量密度。NOAA SP2通过激光诱导发光技术检测光吸收气溶胶，如炭黑（BC），以实现对难熔气溶胶质量和数量密度的实时原位量化。同时，还提供了质量百分比上归因于人为铁氧化物（FeOx）的光吸收气溶胶的比例。
