Abstract

A cloud observational system, which combines ground and satellite measurements, is used to characterize cloud fields over a central area in the Netherlands. The results will be used for the improvement of parameterizations in climate models. In the Netherlands a ground-based cloud detection network of 11 stations is installed. Each station consists of a lidar-ceilometer and an upward looking narrow beam infrared radiometer. The observations of the network are combined with cloud parameters derived from NOAA/AVHRR and Meteosat. Information on the actual atmospheric conditions like standard rawinsonde data, and numerical weather forecast analysis data are also used. The system aims at a detailed quantitative description of cloud cover, cloud structure and radiative properties in an area of 120 by 120 km², the typical size of a general circulation model (GCM) grid box. The cloud detection system (CDS) will be operated for a period of two years. A first analysis of the measurements from the CDS for September 11, 1994 is presented. The ground based measurements are combined with the satellite measurements. It is concluded that this combination of measurements gives a good description of the temporal and spatial variability of the clouds over the TEBEX area. The concept, to use the lidar-ceilometer measurements to derive cloud characteristics for meteorological purposes, has much potential. Thousands of lidar ceilometers are already installed all over the world. The investiments needed to use these measurements for meterological applications would be limited.
