Objectives and Approach
The objective of this project is to obtain a statistically-significant data set of the vertical distribution of aerosol properties (e.g., light scattering and absorption, particle chemistry).
The measurements will be used to answer the following scientific questions:- How do aerosol properties vary through the vertical column?
- Under what conditions can surface-based measurements of these properties be used to calculate the direct aerosol radiative forcing from a measured aerosol optical depth?
The measurements will be made by flying a light aircraft (Cessna C-172N) over the SGP site and utilizing a similar aerosol instrument package to the one at SGP. The aircraft will fly level legs at altitudes between 500 m and 3500 m several times per week over the course of one year. How much aerosol do we miss staying at or below 3.5 km?
This is a joint effort between the ARM program and ESRL/GMD of the U.S. National Oceanic and Atmospheric Administration (NOAA).

Atmospheric Properties
These plots are designed to provide a quick look at the measured aerosol properties. They display raw unedited data, but known corrections for instrument errors have been applied.
