  abstract = {{ We analyse one year of cloud data from the ISCCP C and D datasets. The
two datasets differ by their retrieval algorithms and their definitions
of the cloud types defined from the cloud top pressure and cloud optical
depth. The differences between the two datasets are first described in
terms of the total cloud cover, as well as its repartition in low,
middle, and high level cloudiness. We also project the ISCCP C cloud
classes into the ISCCP D cloud types to circumvent the problem of
different cloud type definitions in the two datasets. The differences
between the two datasets are then also investigated in terms of the most
frequent cloud type.

  abstract = {{The inclusion of a backscatter lidar on a space platform for a radiation
mission, as proposed by various space agencies, aims to bring new
information on three-dimensional cloud distribution, with a special
emphasis on optically thin cirrus clouds, which are presently poorly
detected by passive sensors. Key issues for such cloud observational
studies are the detection of multilayered cloud systems, thin cirrus,
and fractional cloud cover, knowledge that would improve our
understanding of the global radiation budget. To assess the impact of
such lidar measurements on cloud climatology, a 1 month cloud data set
has been simulated with a general circulation model (GCM). The cloud
detection capability of a spaceborne scanning backscatter lidar is
assessed with the use of two detection schemes, one based on limitations
in the detected cloud optical depth and the other based on lidar
signal-to-noise ratio. The cloud information retrieved from passive
radiometric measurements using a procedure like that used in the
International Satellite Cloud Climatology Project is also simulated from
the same GCM cloud data set. It is shown that a spaceborne backscatter
lidar can improve significantly the retrieval of thin cirrus clouds as
well as underlying cloud layers. High-level cloud retrieval from a
spaceborne lidar therefore appears as a powerful complement to
radiometric measurements for improving our knowledge of actual cloud
climatology.

  title = {{Interannual Variations of Summer Monsoons: Sensitivity to Cloud Radiative Forcing.}},
  journal = {Journal of Climate},
  year = 1998,
  month = aug,
  volume = 11,
  pages = {1883-1905},
  abstract = {{The sensitivity of the interannual variations of the summer monsoons to
imposed cloudiness has been studied with a general circulation model
using the initial conditions prepared from the European Centre for
Medium-Range Forecasts analyses of 1 May 1987 and 1988. The cloud
optical properties in this global model are calculated from
prognostically computed cloud liquid water. The model successfully
simulates the contrasting behavior of these two successive monsoons.
However, when the optical properties of the observed clouds are
specified in the model runs, the simulations show some degradation over
India and its vicinity. The main cause of this degradation is the
reduced land-sea temperature contrast resulting from the radiative
effects of the observed clouds imposed in such simulations. It is argued
that the high concentration of condensed water content of clouds over
the Indian land areas will serve to limit heating of the land, thereby
reducing the thermal contrast that gives rise to a weak Somali jet. A
countermonsoon circulation is, therefore, simulated in the vector
difference field of 850-hPa winds from the model runs with externally
specified clouds. This countermonsoon circulation is associated with an
equatorial heat source that is the response of the model to the
radiative effects of the imposed clouds. Indeed, there are at least two
clear points that can be made: 1) the cloud-SST patterns, together,
affect the interannual variability; and 2) with both clouds and SST
imposed, the model simulation is less sensitive to initial conditions.
Additionally, the study emphasizes the importance of dynamically
consistent clouds developing in response to the dynamical, thermal, and
moist state of the atmosphere during model integrations.

  abstract = {{The POLDER radiometer was on board the ADEOS satellite from August 1996
to June 1997. This instrument measures radiances in eight narrow
spectral bands of the visible and near infrared spectrum. Two of them
are centered on the O$_{2}$ A-band in order to infer cloud
pressure. By assuming the atmosphere behaves as a pure absorbing medium
overlying a perfect reflector, an {\rdquo}apparent{\rdquo} pressure
P$_{app}$ is derived from POLDER data. For validation purposes,
P$_{app}$ is first compared to the sea-surface pressure
P$_{s}$ for clear-sky conditions; P$_{app}$ is found to be
close to P$_{s}$ (within {\sim}30 hPa) for measurements in the
sunglint region. For overcast conditions, P$_{app}$ differs from
the cloud-top pressure mainly because of multiple scattering inside the
cloud. When P$_{app}$ is compared to the cloud pressure determined
from brightness temperature measurements, large differences are observed
(typically 180 hPa).
