NASA has announced a new mission to examine ice clouds in Earth’s dynamic atmosphere, especially those forming at high altitudes in tropical and subtropical regions. The mission, using the Polarized Submillimeter Ice-cloud Radiometer , involves two identical CubeSats that will monitor these clouds’ daily ice content cycle. The primary aim is to improve the simulation of these clouds in global climate models and boost climate forecast accuracy.
The investigation consists of two identical CubeSats – each small satellite is just a little over a foot tall – flying in orbits separated by three to nine hours. Over time, these two instruments will observe the clouds’ daily cycle of ice content. A new NASA mission, PolSIR, short for Polarized Submillimeter Ice-cloud Radiometer, will study high-altitude ice clouds, such as this cloud as seen from the International Space Station in 2008. Understanding how such clouds change throughout the day is crucial for improving global climate models. Credit: NASA
