Mission Summary and Fact Sheet
by Jens Redemann
BAERI/NASA Ames Research Center
The primary purpose of this experiment is to validate the over-ocean MODIS aerosol optical depth (AOD) measurements at 1.6 and 2.1micrometer (mm) aboard the Terra and Aqua platform. The primary tool for validating the MODIS AOD is the 14-channel NASA Ames Airborne Tracking Sunphotometer, AATS-14, which will fly aboard the CIRPAS Twin-Otter aircraft out of Monterey, CA. A total of approximately 30 flight hours will be available. The timing of the experiment is chosen to coincide with the maximum transport of Asian dust to the US West coast, one of the few aerosol species with considerable AOD in the near-IR. The basic flight plan will call for a low-level flight leg of 100km horizontal extent, bracketing satellite overpass time, followed by a vertical profile and a level-leg within the dust if present. The level-legs within the dust are intended to provide microphysical characterization while the profiles are expected to yield the vertical structure of aerosol extinction and aerosol-induced flux divergence.
