Instrument : In-situ Aerosol Profiles (Cessna Aerosol Flights) (IAP)

Instrument Categories
Aerosols, Atmospheric Profiling, Airborne Observations

General Overview

The In-situ Aerosol Profiles (IAP) campaign is a joint effort between the ARM Program and the Climate Monitoring and Diagnostics Laboratory (CMDL) of the U.S. National Oceanic and Atmospheric Administration (NOAA). The objective is to obtain a statistically-significant data set of the vertical distribution of aerosol properties (e.g., light scattering and absorption, particle chemistry) by flying a light aircraft over the SGP site. By utilizing a similar aerosol instrument package as the Aerosol Observing System (AOS) at SGP, the aircraft will fly level legs at altitudes between 500 m and 3500 m several times per week. See the IAP website for more information.
