We will build and validate a portable imaging spectrometer that can be flown on a variety of platforms at nearly unlimited temporal resolution and can operate at altitudes lower than clouds to resolve spatial features as small as 30 cm. The proposed sensor has a unique spectrometer and telescope design that will have unprecedented sensitivity for assessing the large dynamic range in observed coastal reflectance at ~3 nm spectral resolution. The sensor performance exceeds the state of the art in light throughput, spectral and spatial uniformity, and polarization insensitivity by factors of 2-10, while at the same time extending the spectral range into the ultraviolet. Our detailed field validation plan will assess sensor performance over a variety of coastal targets, and address how acute and chronic hazards impact the diversity and geographical distribution of coastal habitats. Episodic hazards can restructure the coastal zone, greatly impacting marine and estuarine ecosystems as well as residential communities residing along the coasts. Over one-third of the total human population, nearly 2.4 billion people, live within 100 km of an oceanic coast This region is increasingly affected by a variety of natural and human-induced events from tsunamis to tidal blooms. Current satellite data provide a broad overview of these events but do not have the necessary spectral, spatial and temporal, resolution to fully characterize and understand them. Our airborne sensor will provide the data to fully characterize, understand and possibly predict these events. This proposal contributes to strategic sub-goal 3A of the NASA Strategic Plan to "study Earth from space to advance scientific understanding and meet societal needs". We will serve this goal by advancing airborne sensor technology to address the impact of episodic hazards and pollutants affecting coastal ecosystems and communities in the coastal zone.
