UV-Enhanced Coating — ZC-1069
The Geostationary Littoral Imaging and Monitoring Radiometer (GLIMR) is a future NASA mission, planned for launch but not yet flown: a space-based instrument that will help scientists observe and monitor ocean biology, chemistry and ecology throughout the Gulf of America, the southeastern U.S. coastline and the Amazon River plume that stretches to the Atlantic Ocean. It measures spectral radiances across an approximately 340–1040 nm range.
