The Institute of Meteorology and Climate Research (IMK) Lidar Data are images displaying the polar wind velocity and the polar aerosol concentration.

For elevation scans there are figures at azimuth 0, 60 and 120 degrees, for the azimuth scan there are figures at elevations 7, 12 and 17 degrees available. Angles are indicated in the line above the colourscale.

Vertical scans have been made at elevation 90 degree.

The upper figures are showing polar (radial) velocity, the lower ones aerosol backscatter at the three different angles which are indecated in each figure above the colour scale.

The diagrams are showing unaveraged data. They vizualize a snapshot of approx. 10 minutes measurements starting at the time stated in the filename.

Data were recorded from the 19th of June 2005 to the 29th of August 2005.
