AB: The Short-Wave Aerostat Mounted Imager (SWAMI) is a newly designed remote sensing platform attached to the tether line of a 3500 m3 research balloon. We are using the SWAMI to study terrestrial ecosystems by bridging the spatial gap between radiometric measurements collected near the surface and those collected by other aircraft or satellite. Primary instruments of the SWAMI include an Analytical Spectral Devices Dual VNIR spectrometer, video camera, and thermal infrared sensor, which are mounted upon a pointable view hatch with active stabilization. Secondary instruments include a GPS receiver and numerous meteorological sensors. Downloads of sensor data and remote control of the spectrometer occurs via wireless transmission to a ground control station. The balloon can be flown at altitudes up to 2km AGL. Data collected during Summer 2003 over a ponderosa pine forest, a conifer forest/grassland ecotone, and grassland areas are being used to investigate spectral mixture algorithms commonly used in sub-pixel analysis. Portions of the SWAMI platform are planned for use at an Ameriflux tower site in the Black Hills of South Dakota to collect data relevant to SpecNet. Applications of SWAMI technology to the proposed SpecNet network, including wireless spectrometer control and active pointing control mechanisms, will be discussed.
