| Zusammenfassung |
| By combining AVHRR data from the NOAA
satellites with information from a database of in situ measurements, large-scale
maps can be generated of the microphysical parameters most immediately
significant for the modelling of global circulation and climate. From the
satellite data, the clouds can be classified into cumuliform, stratiform and
cirrus classes and then into further sub-classes by cloud top temperature. At
the same time a database of in situ measurements made by research aircraft is
classified into the same sub-classes and a statistical analysis is used to
derive relationships between the sub-classes and the cloud microphysical
properties. These two analyses are then linked to give estimates of the
microphysical properties of the satellite observed clouds. Examples are given of
the application of this technique to derive maps of the probability of
occurrence of precipitating clouds and of precipitating water content derived
from a case study within the International Cirrus Experiment (ICE) held in 1989
over the North Sea. |
