Aircraft at AAO - Fixed Wing Single-Engine T206H Cessna	Map of Airborne Aerosol Observing, Bondville, Illinois

Inlet at AAO fixed to left side of plane, under the wing, and between the door and the window

The NOAA Airborne Aerosol Observatory was a mobile observatory based near Bondville, Illinois. Samples were collected over the flat, agricultural lands of east central Illinois. The AAO aircraft is specifically outfitted for atmospheric monitoring. Instruments on the aircraft make measurements of aerosol optical properties, hygroscopic growth, aerosol composition, particle number, and size distribution. In addition to aerosol measurements, the aircraft also carried the automated sampling equipment for carbon cycle gas collection. AAO was one of the most frequently sampled locations, often conducting two sampling flights per week. Sample collection began in June 2006, but the site was discontinued in September 2009 because of funding cuts.

AAO Site Data

Figure 1: Annual Climatology is a compilation of all Carbon Dioxide (CO2) time series data that has been collected with the Mauna Loa (MLO) trend removed. The Historical profile includes every CO2 measurement (excluding flagged data) for each month, at each altitude and has been binned to get the monthly average.

Figure 2: Annual Climatology is a compilation of all Carbon Monoxide (CO) time series data that has been collected with the Mauna Loa (MLO) trend removed. The Historical profile includes every CO measurement (excluding flagged data) for each month, at each altitude and has been binned to get the monthly average.

Figure 3: Annual Climatology is a compilation of all Sulfur Hexafluoride (SF6) time series data that has been collected with the Mauna Loa (MLO) trend removed. The Historical profile includes every SF6 measurement (excluding flagged data) for each month, at each altitude and has been binned to get the monthly average.

Figure 4: Annual Climatology is a compilation of all Methane (CH4) time series data that has been collected with the Mauna Loa (MLO) trend removed. The Historical profile includes every CH4 measurement (excluding flagged data) for each month, at each altitude and has been binned to get the monthly average.

Figure 5: Annual Climatology is a compilation of all Nitrous Oxide (N2O) time series data that has been collected with the Mauna Loa (MLO) trend removed. The Historical profile includes every N2O measurement (excluding flagged data) for each month, at each altitude and has been binned to get the monthly average.
