In this paper, a hyperspectral Coastal Image Imager (CI) is proposed to measure key data products from sun synchronous orbit, including water-leaving radiances in the near-ultraviolet, visible and near-infrared for separating and scattering coastal water constituents and for calculation of chlorophyll fluorescence.Abstract:
Resolving the complexity of coastal and estuarine waters requires high spatial resolution, hyperspectral
imaging spectroradiometry. Hyperspectral measurements also provide capability for measuring bathymetry
and bottom types in optically shallow water and for detailed cross calibration with other instruments in
polar and geosynchronous orbit. This paper reports on recent design studies for a hyperspectral Coastal
Imager (CI - pronounced "sea") that measures key data products from sun synchronous orbit. These
products include water-leaving radiances in the near-ultraviolet, visible and near-infrared for separation of
absorbing and scattering coastal water constituents and for calculation of chlorophyll fluorescence. In
addition, CI measures spectral radiances in the near-infrared and shortwave infrared for atmospheric
corrections while also measuring cloud radiances without saturation to enable more accurate removal of
instrument stray light effects. CI provides contiguous spectral coverage from 380 to 2500 nm at 20 m
GIFOV at nadir across 5000+ km2 scenes with spectral sampling, radiometric sensitivity and calibration
performance needed to meet the demanding requirements of coastal imaging. This paper describes the CI
design, including concepts of operation for data collection, calibration (radiometric, spectral and spatial),
onboard processing and data transmission to Earth. Performance characteristics for the instrument and all
major subsystems including the optics, focal plane assemblies, onboard calibration, onboard processing and
thermal subsystem are presented along with performance predictions for instrument sensitivity and
calibration. Initial estimates of size, mass, power and data rate are presented.read more

Coastal water camera system
TL;DR: In this paper, the authors describe a Coastal Water Camera System (CWCS) that provides the wide field of view, high spatial resolution and high SNR imaging spectroradiometry at ultraviolet (UV) through near infrared (NIR) wavelengths needed to meet challenging requirements for coastal water measurements from polar sun synchronous orbit (SSO).

TL;DR: The Marine Optical Buoy (MOBY) has been the primary in-water oceanic observatory for the vicarious calibration of U. S. satellite ocean color sensors, including the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) and the Moderate Resolution Imaging Spectrometers (MODIS) instruments on the National Aeronautics and Space Administration's (NASA's) Terra and Aqua satellites as discussed by the authors.
