The Cabauw Observatory is located in the western part of the Netherlands (51.971° N, 4.927° E) in a polder 0.7 m below average sealevel. At the site a large set of instruments is operated to study the atmosphere and its interaction with the land surface. The Cesar site is used for:
- Monitoring of long term tendencies in atmospheric changes
- Studies of atmospheric and land surface processes for climate modelling
- Validation of space-borne observations
- The development and implementation of new measurement techniques, and
- Training of young scientists at post-doc, PhD and master level
Three universities and five major research institutes collaborate in Cesar. It is the focal point of experimental atmospheric research in The Netherlands.

A 213 m high mast was specifically built at the Cabauw site for meteorological research to establish relations between the state of the atmospheric boundary layer, land surface conditions and the general weather situation for all seasons.
