Scientific paper

Observations from the Solar Occultation For Ice Experiment (SOFIE) reveal that ice particles near the polar summer mesopause generally exist in a continuous layer extending from roughly 80 km to above the mesopause. Ice particles at the lower altitude range have been observed visually as noctilucent clouds (NLC) and remotely as polar mesospheric clouds (PMC). Radars detect polar mesospheric summer echoes (PMSE), which typically extend from just below PMC altitudes to the mesopause and above. PMSE are attributed to changes in the radio refractive index due to the presence of ice particles which acquire a charge in the ambient D-region. Based on simultaneous lidar NLC and radar PMSE observations, it has long been suspected that both phenomena are different manifestations of the same mesospheric ice clouds. Due to the high sensitivity of SOFIE and its ability to detect even tiny ice particles, this hypothesis can now be rigorously tested. We explore relationships between PMC and PMSE using radar observations in the northern and southern polar regions, in conjunction with SOFIE ice measurements.
