INO LIDAR in Antarctica

A tropospheric depolarization LIDAR has been installed in 2008 at Concordia Base (Antarctica, DOME C, 75° S 123° E).
The instrument is "alive" within the framework of the projects TAVERN (ISAC CNR) , ICE-CAMERA & PRANA (IFAC CNR), PRE-REC & COMPASS (INO CNR)
national (Programma Nazionale Ricerche in Antartide) projects.
The LIDAR is mounted on an aluminium frame inside a shelter that is located 500 m from the mainbase, in the “Clean Air Area”.

Double optical windows flushed with pre-heated external air make the operation of the LIDAR possible in all weather conditions,
even on -80°C cold polar nights.
The LIDAR is intended to provide tropospheric profiles of aerosol and clouds every 5 minutes, 24 hours/24. The system is fully automatic. Housekeeping data and local meteo data are collected and stored together with the LIDAR data.
Data are sent to Italy for inspection on a daily basis.
Time-lapse videos of local sky conditions are also automatically collected
.


Le main specs of the Concordia LIDAR are the followings:

-Laser Quantel Brio (532, lin. pol.)

-Telescope : refractive, 10 cm diameter, f/3

-Data acquisition: Licel GmbH, analog, 2 channels (532 nm p, s)

-Vertical resolution: 7.5 m

-Altitude range: 30 m -12000 m a.g.

-Webcam: analog B/W SK-1004XC/SO with 3.6 mm lens

Here are all the Concordia LIDAR data collected from 2008 to 2013.

The quality is variable, because of many troubles occurred to the lasers.

From 2013 on we have complete yearly statistics...

.... and now the instrument is the only fully automatic depolarization LIDAR in Antarctica !
