The Polarized Submillimeter Ice-cloud Radiometer (PolSIR) is a NASA space mission consisting of two 16U CubeSats flying in low Earth orbit, expected to launch in 2028.[1][2] This mission intends to measure characteristics of ice clouds in tropical and subtropical regions (between 35 degrees North and South latitude) to improve understanding of Earth's dynamic atmosphere.[3][4] This mission follows the previous successful NASA CubeSat mission also studying ice clouds with radiometry, IceCube.
