The Davis Lidar Laser

Flashlamp (Ice clouds)

So many hours of LIDAR (Light Detection And Ranging) operation at Davis it gives result in the first ground-space synchronized inspection of 'Polar Mesospheric Clouds - when viewed from space' or 'Noctilucent clouds - when viewed from the ground' on whole Antarctica.

These very thin ice clouds point out to the temperatures lower that -130 degrees Celsius where they appeared approximately 83 km elevation. Rising amount of noctilucent clouds is estimated from the cooling result of rising carbon dioxide at high elevation.

An exclusive polar mesospheric cloud detain on the LIDAR on New Years Day/Eve persevere for 22 hours and approximately jumped off the brightness scale.

Australian Antarctic Division's distinctive radar also documentation related intense 'blobs' or to the Ice, Ocean, Atmosphere and Climate scientists 'Polar Mesosphere Summer Echoes'.

Wonderfully, orbiting Davis at this time it was the ' AIM (Aeronomy of Ice in the Mesosphere)' spacecraft - that is recorded its brightest and thickest PMC layer to date.

The revise of these ice sheet that form at the circumference of room in the altitude variety of 80 to 94 km by using the Australian Antarctic Division's Davis LIDAR and RADARS, and the NASA AIM spacecraft instruments - is paying attention on formatting whether their rising brilliance and opportunity coverage are an indicator of climate change in the atmosphere.

This investigate is division of the Ice, Ocean, Atmosphere and Climate program involvement to the International Polar Year science objectives.
