2016 Silver Medal Award

Brown, Lykee

AWARD CITATION

The group is recognized for developing and applying an innovative laser-based method to the calibration of VIIRS, the premier instrument on both the Suomi-NPP satellite and the soon-to-be-launched Joint Polar Satellite System.  The group demonstrated that their method provides a full system-level calibration of the sensor, lowers calibration uncertainties by an order of magnitude, reduces calibration time from 20 to 3 days, and accurately quantifies subtle stray-light and light-polarization effects that impact the most demanding VIIRS on-orbit measurement, that of ocean color.
