Abstract

The Improved Radiometric calibration of land Imaging Systems or IRIS is a compact full-spectrum calibration system that reduces the size, weight and power of conventional on-board radiometric sources into a single flat panel format by combining both carbon nanotube and LED technology within a Jones source design. Introduced in this presentation is a methodology that maintains in-flight traceability through a fusion of the on-board IRIS LED reference with Labsphere’s FLARE vicarious calibration system. The process known as IRIS-V provides SI traceability of the on-board VSWIR calibration system through the mission's lifetime without impacting operational land or coastal image collection.
