Validation of upper mesospheric and lower thermospheric temperatures measured by the Solar Occultation for Ice Experiment
[1] Temperature observations in the polar mesosphere and lower thermosphere are critical for studies of polar mesospheric cloud (PMC) formation and variability. The Solar Occultation for Ice Experiment (SOFIE) on NASA’s Aeronomy of Ice in the Mesosphere (AIM) satellite has been measuring temperature...
