Five different plots show the temporal evolution of the range-corrected signal (arbitrary units) at 355, 532 and 1064 nm. The backscattering intensity increases from cold to warm colors. White represents strong backscattering, which is often caused by clouds.
The 355-depol plot shows the ratio of the depolarization signal and the total signal at 355 nm. The depolarization intensity increases from cold to warm colors. Larger depolarization indicates more non-spherical particles and ice crystals in case of clouds, respectively.
In the four above mentioned plots the temporal and spatial resolution is 30 sec and 30 m, respectively.
The 532-analog plot shows the range-corrected signal at 532 nm, but with a temporal and spatial resolution of 10 sec and 7.5 m, respectively.
On the website the last done measurements are plotted and a link to the archive of old measurements is shown.
Measurements taken before January 2008 were performed in Leipzig, while the current location of the lidar is at the Silvicultura Site near Manaus, Brazil.
Because we are still optimizing our system all data are preliminary. So, the information from the web-page can be used for first information but is not thought for scientific publications.
