Platform: NASA DC-8 Payload
The NASA DC-8 instrument payload is chosen to characterize the atmospheric composition in urban and marine environments with more detailed in-situ measurements than any previous aircraft campaign. The payload will be capable of addressing all of the major science questions for AEROMMA. We propose to equip the NASA DC-8 aircraft with a complete set of gas phase, aerosol composition and optical properties, and radiation measurements. Most instruments will have a high enough sampling frequency to be able to do wavelet eddy covariance flux measurements to determine emissions and deposition of VOCs, NOx, CO, CO2, and CH4.
