Technical Abstract

In this Phase I study, a unique aerosol phase function monitor will be developed. It will utilize an aerodynamic lens to collimate and separate poly-dispersed aerosols based on their differences in vacuum aerodynamic diameters. It will be capable of measuring aerosol scattering intensity at multiple angles simultaneously with respect to the incident laser beam after a period of particle time of flight, which is dependent on aerosol vacuum aerodynamic diameter. Thus the proposed technique is capable of determining size-resolved scattering phase function as well as asymmetry factor of atmospheric aerosols from 100nm to 1000nm in real-time.

Potential NASA Applications

The proposed instrument will allow real-time measurements of size-resolved scattering phase function and asymmetry factor of atmospheric aerosols from 100nm to 1000nm for NASA's Airborne Measurement Program. A field-deployable prototype will be a deliverable at the end of the Phase II study.

Potential Non-NASA Applications
  1. Characterization of synthetic metallic and semiconductor nanoparticles from various generation sources
  2. Monitoring local air quality for environmental investigations
