In October 2008, Biospherical Instruments embarked on a joint project with NASA to develop and deploy a state-of-the-art above-water radiometer system in support of current and next-generation ocean color satellite missions. The system is called Optical Sensors for Planetary Radiant Energy (
OSPREy), and will provide high-quality measurements of the sea, Sun, sky, and Moon. The measurements will satisfy the accuracy requirements for the vicarious calibration and algorithm validation of ocean color satellites.
