Lidar Data from Brazil

The FISAT home page on the WWW is 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.
