Comparison of CS135 and CL51 during WOEST - CS135 looks noisier #43

Report from Chris Walden - "Have to say the CCS135 lidar is not ideal. Comparing with the CL51 at chilbolton here:https://cloudnet.fmi.fi/search/visualizations?site=chilbolton,mod-lyneham&product=lidar&dateFrom=2023-06-29&dateTo=2023-06-29"

Attached my quicklook, stretched to a similar aspect ratio to the cloudnet ones.

Seems odd that the cloudnet plot shows the cs135 data in the boundary layer right on the bottom of the colourscale at 1e-7 sr-1 m-1 as through it is off scale and therefore all detail is lost. Whereas my quicklook shows the boundary layer data in the range 7e-6 to 2e-5, with some detail (albeit less than the CL51)
