  abstract = {{Twilight data obtained photographically from a stratospheric balloon
platform in the autumns of 1980 and 1981 and in the spring of 1982 are
presented for blue and red light. They indicate the presence of a light
absorbing layer and of a scattering layer in the mesosphere at altitudes
near 60 plus or minus 10 km with a low scattering albedo (0.1) at 0.44
micron if it is accepted that both the extinction and scattering
originate from dust. The optical efficiency of the layer increases more
than 10 times when the wavelength of the interacting light changes from
0.65 to 0.44 micron. At the zenith and near sunset, the natural
0.44-micron extinction optical thickness and the sq cm column scattering
rate due to this layer are found to be 0.066 and 0.18 MRA respectively
on 3 May 1982 above the south-west of France.

  abstract = {{A statistical classification method based on clustering on
three-dimensional histograms is applied to the three channels of the
METEOSAT imagery [Visible (VIS)-Infrared Window (IR)-Infrared Water
Vapor (WV)]. The results of this classification are studied for
different cloud cover cases over tropical regions. For high-level cloud
classes, it is shown that the bidimensional histogram IR-WV allows one
to deduce the cloud top temperature even for semi-transparent clouds.
