Vertical Profiles of Tropospheric Cloud Optical Parameters measured in Antarctica using a LIDAR System

The format of this measure data set follows the File Format Specifications
NASA-AMES used in many international campaigns on atmospheric soundings.
Data set names are coded as follows:
CXdddHMN.TXT where:
C means clouds measure
X = year code (A=1989, B=1990 ...)
ddd = julian day of the measure date
H = hour of the measure time
M = minutes tens of the measure time
N = measure progressive index
Primary variables are the vertical profiles of the following parameters:
- Squared Range corrected Lidar Signal (Pr2)
- Aerosol Backscattering and Scattering Ratio by Lidar
- Depolarisation ratio by Lidar (if available)
- Pressure,Temperature and Humidity by Rawinsonde (if available)
- O3 by Ozonesonde (if available)
The Depolarization Backscattering Lidar is part of a more complex
DIAL System by a scientific cooperation between Service d'Aeronomie of
CNRS (France) and IROE of CNR (Italy).
Rawin- and Ozone-sonde are by Dumont d'Urville French Antarctic Station.
All the profiles are normalized to the same altitudes.
The profiles range are related to the cloud altitude and depth.
The altitude resolutions are 30 or 75 m.
A set of "auxiliary variables" preceed each group of profiles. They are:
- Number of altitudes of the profiles
- Date and Time,Averaging Time of the Lidar measure
- Laser emission wavelength
- Number of the integrated Lidar shots
- Date and Time of the Rawinsonde launch (if available)
- Latitude and Longitude
- Coefficients for Extinction computing
- Integrated Backscattering,Optical Depth with bottom and top edge
- Telescope Field of View
- Bandwidth of the interference filter
A description header in the data set contains further details.
A suitable processing routine by IROE computes the lidar profiles by
row lidar signals that are not directly useful for scientific purposes.
