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 to the one at SGP, the aircraft will fly level legs at altitudes between 500 m and 3500 m several times per week. See the IAP website at http://www.cmdl.noaa.gov/aero/net/iap/index.html for more information.
