After AirMISR's retirement in 2004, parts from that airborne instrument were used to construct a new instrument called the Airborne Multi-angle SpectroPolarimetric Imager or AirMSPI. AirMSPI added polarimetric capabilities while continuing the approach of using a single camera mounted on a gimbal to obtain multi-angular imagery. It has served as a prototype for the development of the Multi-Angle Imager for Aerosols (MAIA) satellite instrument. AirMSPI's first flight on the NASA ER-2 spacecraft took place in 2010.

The technical details of AirMSPI are maintained on the JPL Airborne Sciences website. AirMSPI data are catalogued at the Atmospheric Sciences Data Center.
