Lidar Data from Brazil

The FISAT home page on the WWW is http://www.laser.inpe.br/fisat/ .

This set contains data obtained at the location of Sao Jose dos Campos
(23 degrees S, 45 degrees W), only.

>From 1972 to 1981 only night-time data of the Lidar backscatter return
at 589.0 nm are available. The periodicity of the data is
irregular. Generally short-duration measurements (less than 2 hours)
are available at about one measurerent per week. Long-duration data
covering most of the night are available in a few campaigns. Data are
also given, in processed form, providing aerosol backscatter ratio
from 15 to 30 km altitude and sodium density from 75 to 105 km
altitude.

>From 1981 to 1993, campaigns of sodium measurements taken during the
day, including several diurnal cycles are also available.

>From 1983 to the present day a new powerful laser at 593.0 nm provides
the Rayleigh scatter profiles giving the atmospheric density and
temperatures from 35 to nearly 70 km altitude. Data are currently
obtained, approximately, on a weekly basis.
